NaʻO Jake Morrison, Mea kākau Lako|Sarah Chen|Mike Patterson
Paʻi ʻia:Fepeluali 8, 2025
ʻOi aku ka nui o nā mea a pau e hoʻihoʻi hou ʻia i kēia mau lā e holo ana ma nā pākaukau lithium ion. ʻO kāu kelepona, maopopo. Laptop. ʻO kēlā mau pepeiao pepeiao ʻole paha āu e ʻaʻahu nei i kēia manawa. Ua hoʻomaka ka ʻenehana i ka makahiki 1991 i ka wā i kūʻai aku ai ʻo Sony i nā kelepona lithium ion mua no nā camcorders, a ua ʻai ʻo ia i kēlā me kēia ʻāpana huahana mai ia manawa.
Nīnau ka poʻe "he aha nā ʻeke lithium ion" e manaʻo nei i kahi papa inoa maʻalahi, akā ʻo ka pane maoli: hele e nānā a puni kou hale. E helu i nā mea hoʻopiha hou. ʻO ia kāu pane.
Hoʻopaʻa kēia mau ʻaʻa i ka ikehu ma ka hoʻopaʻa ʻana i nā ion lithium ma waena o ʻelua electrodes-anode i ka cathode i ka wā e hoʻokuʻu ai, hoʻohuli i ke ala ke hoʻopili ʻoe iā lākou.
No ke aha i lanakila ai ka Lithium Ion
ʻEkolu kumu. ʻOi aku ka ikaika o ka ikehu i nā mea ʻē aʻe. He 150-250 watt-mau hola no ka kilo pākahi. E hoʻohālikelike i kēlā me ka nickel-cadmium ma kahi o 40-60 Wh/kg. ʻAʻole kokoke.
ʻO ka lua, ʻaʻohe hopena hoʻomanaʻo. E hoʻomanaʻo i nā kelepona ʻole kahiko kahi āu e hoʻokahe piha ai i ka pākaukau a i ʻole e "poina" i kona piha piha? ʻAʻole hana ka Lithium ion i kēlā. E hoʻopaʻa i kēlā me kēia manawa. ʻO ke kolu, ʻo ka haʻahaʻa haʻahaʻa-hoʻokuʻu iho-ua hoʻopaʻa lākou i kā lākou hoʻokele e noho ana ma kahi papa, e nalowale ana paha he 2-3% o kēlā me kēia mahina ma mua o 20% no nā ʻaniani NiMH.
Ua emi iho ke kumukūʻai. Ma hope o nā makahiki 90, ua nui ke kumukūʻai o kēia mau pila a ua hoʻohana wale nā mea uila uila iā lākou. I kēia manawa ua lawa lākou no nā mea hoʻoili USB hale kūʻai kālā. ʻAe, kūʻailawa-ʻoi aʻe ka pipiʻi ma mua o ka alkaline, akā e uku wikiwiki ʻia ka rechargeability.
Mea Hoʻohana Electronics (The Obvious Stuff)
Ke alakaʻi nei nā kelepona i ka pūʻulu. Loaʻa iā iPhone 15 Pro kahi pākaukau 3,274 mAh. ʻOi aku ka nui o Samsung Galaxy S24 Ultra ma 5,000 mAh. Ke hoʻohana nei kēlā me kēia kelepona mai $50 mau kumu hoʻohālike i uku mua ʻia a hiki i $1,500 mau hae hae lithium ion -maʻamau lithium cobalt oxide (LCO) kemika no ka mea e hoʻonui ana i ka hiki ma nā wahi ākea.
E holo ana nā kamepiula kamepiula i nā ʻōhua nui, maʻamau 50-80 Wh no nā ultrabooks, a hiki i 100 Wh no nā hale hana. ʻOiaʻiʻo, ʻo 100 Wh ka palena kānāwai no ka lawe ʻana i nā pihi ma nā mokulele me ka ʻole o ka ʻae ʻia, ʻo ia ke kumu e hoʻoholo ai nā mea hana kamepiula i kēlā helu. Ua hoʻonohonoho ka FAA i kēlā kānāwai ma hope o ke ahi ʻana o nā pahu lithium i nā mokulele i ka makahiki 2000.
Aia nā papa ma waena o -iPad Pro ma kahi o 40 Wh. Kindle Paperwhite? ʻO ka pilahi liʻiliʻi 6 Wh mau pule no ka mea e-ʻīnika e hōʻike ana i ka mana sip.
A laila aia nā mea ʻē aʻe a pau. Nā ʻiole uwea ʻole a me nā kīpī (maʻamau maʻamau ka nui o AAA-sele lithium ion cell). Nā leo Bluetooth -JBL, Ultimate Ears, Bose, lithium ion a pau. Nā mea hoʻoponopono pāʻani. Nā wati akamai. Nā mea hoʻoikaika kino. Nā pahupaʻikiʻi palekana uila. Nā bele puka wikiō. Pahū niho uila. Hoʻohana ka moʻo Oral{11}}B iO i ka pākaukau lithium maikaʻi no ʻelua pule ma waena o nā kau.
Loaʻa iā AirPods Pro he 1.98 Wh o ka mana pākaukau i hui pū ʻia ma waena o nā earbuds a me ka pahu. ʻAʻole kani like a hiki i kou ʻike ʻana e hoʻoikaika ana lākou i ka hoʻopau ʻana i ka walaʻau, ka hoʻoili leo spatial, a me ka hoʻohui ʻana i ke kelepona no nā hola.
Kaʻahele-Ma kahi e nui ai nā mea
Ua hoʻololi loa nā kaʻa uila i ka unahi. Hoʻokomo ʻia ʻo Tesla Model 3 Long Range i kahi pākaukau 75 kWh-he 75,000 watt-hola, a i ʻole ma kahi o 1,500 mau ʻokoʻa kelepona paʻa o ka ikehu. ʻO ka pākaukau wale nō ma kahi o 1,000 paona.
Hoʻohana ka hapa nui o nā EV i ka nickel manganese cobalt (NMC) a i ʻole lithium iron phosphate (LFP) kemika ma mua o ka cobalt-ke kaumaha ma nā kelepona. Hāʻawi ʻo NMC i ka nui o ka ikehu maikaʻi me ke kūpaʻa wela maikaʻi. ʻOi aku ka palekana a ʻoi aku ka lōʻihi o ka lōʻihi-BYD a me Tesla i ka LFP no nā hiʻohiʻona maʻamau i kēia manawa. ʻO ke kūʻai aku-he haʻahaʻa haʻahaʻa o ka ikehu, no laila pono ʻoe i nā kelepona hou aku no ka laulima like.
ʻO Ford F-150 Lightning a hiki i ka 131 kWh i loaʻa. Hele ʻo Rivian R1T i 135 kWh i ka hoʻonohonoho Max Pack. Ua koi ʻo Lucid Air Dream Range i ka 112 kWh a loaʻa iā ia ma mua o 500 mau mile o ka laulā EPA no ka mea ʻoi aku ka maikaʻi o kā lākou mau kaʻa a me nā uila.
Ke ulu nei nā kaʻa uila. Hoʻohana maʻamau ʻo Rad Power Bikes i nā ʻeke 48V 14Ah (672 Wh). Paʻa paikika -hopena kiʻekiʻe aʻe mai Specialized a Trek run 500-700 Wh batteries. ʻOi aku ka liʻiliʻi o nā scooters-Xiaomi M365 i ka 280 Wh, Bird a me Lime hoʻolimalima scooter e holo like.
Ke hoʻomau nei nā kaʻa kaʻa uila akā ke ulu nei. Loaʻa iā Zero Motorcycles SR/F kahi pākahiko 14.4 kWh. Hoʻokuʻu ʻo Energica Ego+ i 21.5 kWh. ʻAʻole lawa no nā huakaʻi alanui lōʻihi, akā hiki i laila.
E holo mai ana na waapa. Holo ka moku uila ʻo X Shore Eelex 8000 i kahi pūʻolo pākahiko 125 kWh. Hoʻohana ʻo Candela C-8 hydrofoil boat i 44 kWh a "lele" ma luna o ka wai e hōʻemi i ka huki. Aia ʻo Arc Sport uila wakeboard waʻa ma $300,000 i ka manawa hope aʻu i nānā ai.
Ua hele ʻole nā mea hana mana
Ua wikiwiki kēia hoʻololi. He iwakālua makahiki i hala aku nei, ua ʻakaʻaka ka poʻe ʻaelike koʻikoʻi i nā mea hana cordless. I kēia lā? Milwaukee, DeWalt, Makita, Bosch-ua pau lākou i ka lithium.
Holo ka ʻōnaehana FlexVolt o DeWalt i ka 20V a i ʻole 60V ma muli o ka hāmeʻa. Aia ma luna o 200 mau mea paahana ma Milwaukee M18 e kaʻana like ana i ka ʻōnaehana pākahi. Ua lawa ko lākou mau ʻokoʻa kiʻekiʻe Output 12 Ah -no ka holo ʻana i ka ʻili pōʻai ma o nā ʻoki ʻoki.
Ua ukali nā lako mana waho. Hana ʻo Ego Power Plus i ka mower mauu pākaukau me ka pūʻolo 56V 7.5 Ah (420 Wh). ʻO kā lākou mau mea ʻoki kaula, nā mea puhi lau, a me nā mea puhi hau hoʻi e holo ana i ka paepae pākahi like. He ʻōnaehana 40V ʻo Ryobi. Hāʻawi ʻo Greenworks i nā koho 60V a me 80V no nā lako ʻoi aku ka nui.
E holo ana ka robot vacuums a me ka lawn mowers i nā ʻenekini liʻiliʻi mai ka wā e hoʻihoʻi maʻalahi lākou. Loaʻa iā Roomba j7+ ma kahi o 60 Wh. Hoʻohana ʻo Husqvarna Automower i ka 18V lithium ion, ʻokoʻa ka mana ma ke ʻano hoʻohālike.
Ke ulu mau nei nā lako ʻoihana. Hana ʻo Milwaukee i kahi pākahiko backpack e hāʻawi ana i 300 Wh no ka holo ʻana i nā mea hana he nui ma nā kahua hana. Hāʻawi ʻo Stihl i nā kaulahao pākaukau ikaika no ka hana lāʻau kalepa.
Nā Mea Lapaʻau (Ma kahi o ka hilinaʻi nui loa)
He mea koʻikoʻi nā concentrators oxygen portable no ka poʻe me nā maʻi hanu. Hoʻohana ʻo Inogen One G5 i kahi pākahi lithium ion e hāʻawi ana i nā hola 3-6 o ka hana ma muli o nā hoʻonohonoho kahe. Pili ʻo Phillips Respironics Simply Go Mini ma kahi o 4.5 mau hola.
Hāʻawi nā mīkini CPAP no ka apnea hiamoe i nā koho pākaukau. Hiki i ka CPAP huakaʻi ResMed AirMini ke holo i waho o nā ʻeke lithium waho. Maikaʻi no ka hoʻomoana a i ʻole ka pau ʻana o ka mana.
Ua hoʻololi ʻia nā mea hoʻolohe i ka lithium i hoʻopaʻa hou ʻia. Hoʻolimalima ʻo Phonak Audeo Paradise i ka pō a holo 16+ hola. Starkey Evolv AI hana like. ʻOi aku ka maikaʻi ma mua o ka ʻimi ʻana i kēlā mau puʻupuʻu puʻupuʻu zinc -air i kēlā me kēia lā.
Lapaʻau nānā lapaʻau-nā paʻi koko, nā mea nānā glucose, nā lako ECG lawe lima-he nui i kēia manawa. Hoʻopaʻa ʻo AliveCor KardiaMobile i nā ECG ma ke kelepona, e holo ana ma ke kelepona lithium liʻiliʻi mau mahina.
ʻO nā pamu infusion, nā mea hana ʻokiʻoki, nā mea hana diagnostic i hoʻohana ʻia i loko o nā halemai-he nui nā ʻōhua lithium ion backup a i ʻole nā koho mana lawe lima. Ke hoʻohana nei ka Stryker System 8 i nā mea hana mana o ka mana o ka lithium ion, i hoʻopaʻa ʻia no ka hoʻohana ʻana i ka lumi hana.
He ʻano ʻokoʻa ʻokoʻa nā mea i hoʻopili ʻia. Ke hoʻohana nei kekahi mau mea pacemaker hou i nā ʻona lithium ion hiki ke hoʻopaʻa ʻia i ka transcutaneously (ma o ka ʻili) me ka hoʻohana ʻana i ka hoʻokomo. Loaʻa i ka Medtronic nā hiʻohiʻona kahi e hoʻihoʻi ʻia ai ka pākaukau i hoʻokahi manawa i hoʻokahi pule ma mua o ka pono o ka hoʻololi ʻana i kēlā me kēia 7-10 mau makahiki.
Ka mālama ʻana i ka ikehu (mai nā hale a hiki i ka pālākiō mānoanoa)
ʻO Tesla Powerwall 2 hale kūʻai 13.5 kWh, nā kumukūʻai ma kahi o $ 11,000 i kau ʻia. Ua puka mai nei ka Powerwall 3 me ka hoʻohui maikaʻi. Hāʻawi ʻo Generac PWRcell i nā ʻōnaehana modular 9-18 kWh. Hele ʻo LG Chem RESU mai 10-16 kWh ma muli o ka hoʻonohonoho.
Hoʻopili kēia mau ʻakika home me nā panela solar-e mālama i ka hana keu i ke ao, hoʻohana ia i ka pō. E hāʻawi pū i kahi hoʻihoʻi i ka wā o ka pau ʻana inā hoʻonohonoho pono ʻia. ʻAʻole hana nā ʻōnaehana a pau i ka wā ʻeleʻele; pili i ka hoʻonohonoho inverter.
Ua kauoha ʻo Kaleponi i ka lā ma nā hale hou, no laila ke wikiwiki nei ka lawe ʻana i ka pākaukau ma laila. He kiʻekiʻe nā kumukūʻai uila o Hawaiʻi me ka nui o ka lā, e hana maikaʻi ana ka ʻoihana mālama lā + mālama. Ua loaʻa ʻo Texas i kēlā hemahema i ka makahiki 2021 i hoʻoiho i ka hoihoi i nā pā hale.
ʻOi aku ka nui o nā hoʻonohonoho ʻoihana. Hiki i kahi hale kū'ai ke ho'okomo i 50-100 kWh o nā 'aniani no ka ho'okele koi. Hoʻohana nā kikowaena ʻikepili i nā lumi pākaukau megawatt-scale no ka mana hoʻihoʻi, hoʻololi a hoʻohui ʻana i nā mea hana diesel.
He ʻāhiu ka pālākiō hoʻohana. ʻO ka Moss Landing Energy Storage Facility ma Kaleponi he 3,000 MWh o ka mana-ʻo ia hoʻi 3 miliona kilowatt-hola, a i ʻole lawa no ka mana ma kahi o 225,000 mau hale no kekahi mau hola. Hoʻohana ʻo ia i nā ʻāpana Tesla Megapack, ʻo kēlā me kēia mea he pahu hoʻouna -ka nui 3 MWh pākahiko.
ʻO ka Hornsdale Power Reserve ʻo Australia kekahi o nā pahu pahu nui mua, i kūkulu ʻia e Tesla ma 2017 ma 150 MWh. Ua hoʻonui ʻia mai. Hoʻopaʻa kēia mau ʻōnaehana i ka alapine grid, mālama i ka ikehu hou, hoʻemi i ka pono no nā mea kanu peaker kūlohelohe.
Nā noi kūikawā a puni
ʻO nā ʻōnaehana UPS (uninterruptible power supply) i hoʻohana maʻamau i nā ʻeke -acid lead. Kaumaha, pono e pani hou i kēlā me kēia 3-5 makahiki, loaʻa nā mea ʻawaʻawa. ʻO nā ʻōnaehana Lithium ion UPS mai APC, Eaton, Vertiv ka lōʻihi loa, lawe liʻiliʻi i ka wahi, ʻoi aku ka kaumaha. ʻO nā kikowaena ʻikepili e like me kēia-hōʻemi kaumaha ʻo ia hoʻi ka liʻiliʻi o ka ukana i loko o nā hale.
ʻO nā drones a me quadcopters-DJI ka mea i hoʻomalu i kēia mākeke. ʻO kā lākou mau drones e holo i nā pākahi lithium polymer (LiPo), ʻo ia hoʻi he ʻano ʻano lithium ion me ka polymer electrolyte. Hoʻohana ʻo DJI Mini 3 Pro i kahi pākaukau 2453 mAh ma kahi o 34 mau minuke manawa lele. ʻO nā drones nui aʻe e like me ka Inspire 2 e lawe ana i ʻelua mau ʻāpana ʻelua he 98 Wh.
ʻO nā drones ʻoihana no ke ana ʻana, ka nānā ʻana, ka hāʻawi ʻana-holo lākou a pau i nā pākahi lithium. Hoʻohana ʻia nā drones hoʻopuka olakino Zipline ma ʻApelika i ka lithium ion. Hoʻohana nā prototypes drone hoʻopuka a Amazon iā lākou.
Hoʻonui ʻia nā noi Aerospace. Ke hele mai nei nā mokulele uila. Loaʻa iā Pipistrel Velis Electro nā pākahi lithium-ka mokulele uwila piha mua i hōʻoia ʻia no ka hoʻomaʻamaʻa lele ʻana ma ʻEulopa. ʻO Beta Technologies a me Joby Aviation e hoʻomohala ana i nā ʻauhau ea uila e hoʻohana ʻia e nā pā pākaukau lithium nui.
Hoʻohana nā Satellites a me nā mokulele mokulele i nā pākahi lithium ion kūikawā i kūkulu ʻia no ke ola ʻana i ka momi, radiation, nā wela wela. Loaʻa i ka International Space Station nā pākahi lithium ion e pani ana i nā kinikini-hydrogen kahiko. He 400+ paona ke kaumaha o kēlā me kēia module pākahiko.
ʻO nā lako kaua-nā maka maka maka pō, nā lekiō hoʻolālā, nā pūʻulu GPS, nā ʻōhua lithium e holo nei i kēia manawa. ʻOi aku ka maikaʻi o ka ikehu i ka wā e lawe ai nā koa i nā lako no nā lā. Ke hoʻohana nei ka lekiō AN/PRC-163 i nā pākahi lithium ion hiki ke hoʻouka hou ʻia.
Nā pahupaʻikiʻi a me nā mea paʻi kiʻi-nā pahupaʻikiʻi aniani ʻole mai Sony, Canon, Nikon a pau lithium ion. Hoʻohana ʻo Sony A7 IV i nā ʻoni NP-FZ100 ma 16.4 Wh pākahi. ʻO nā kukui ʻoihana -Aputure 300d LED nā kukui e holo ana ma V-mauna lithium batteries (98 Wh ka nui maʻamau). ʻO nā microphones ʻole, nā kiaʻi wikiō, nā mea lawe lima a pau i ka hana kiʻiʻoniʻoni/kiʻi.
ʻO nā Bateri Hoʻohui a me ka Hoʻokele
Loaʻa pinepine ʻia nā huahana uila hou aʻe-no Bluetooth a i ʻole Wi{1}}Fi. Hiki iā ʻoe ke nānā i ke kūlana pākaukau ma kāu kelepona. Hōʻike nā mea hana mana ʻo Ego i ke kiʻekiʻe o ka uku ma kahi app. ʻO nā mea hana Ryobi pū kekahi. Hāʻawi ʻo Tesla iā ʻoe e nānā i ka pākaukau o kāu kaʻa a me ka hoʻopaʻa ʻana mamao.
Hana nui nā ʻōnaehana hoʻokele pākaukau akamai (BMS). Hoʻohālikelike lākou i ka uila uila -i loko o kahi pūʻulu kelepona he nui, ʻauheʻe nā pūnaewele hoʻokahi i ka manawa, hoʻokaʻawale ka BMS iā lākou. Nānā lākou i ka mahana, pale i ka overcharging a me ka overdischarging, kamaʻilio i ke kūlana i ka hāmeʻa.
ʻO kekahi mau hiʻohiʻona pili i manaʻo ʻia he gimmicky, akā ʻo ka nānā mamao ʻana no nā lako makamae he kūpono. Hiki i nā poʻe hana hale ke ʻike i nā ʻeke e pono e hoʻouka. Hiki i nā mea mālama mālama home ke nānā i ka hana ʻana o ka lā a me ke kūlana pākaukau i ka wā e hele ana.
Aia naʻe nā pilikia palekana. Pono ka paʻa paʻa pila i nā mea hou i kekahi manawa. Inā ʻaʻole i hoʻopaʻa pono ʻia kēlā ala kamaʻilio, he pilikia paha ia. ʻAʻole nui ka poʻe e hack i nā pā, akā ma ke kumumanaʻo hiki.
Maoli -Mauna Hoohana
Kūleʻa nā kānaka i nā pākahi lithium me ka noʻonoʻo ʻole. Pahū niho uila i loko o ka lumi lua. Mea hoʻomaʻemaʻe cordless (Dyson V15 he 70 Wh). ʻO ke kukui uila hiki ke hoʻouka hou. Ka panakō mana ma kāu ʻeke-Hana ʻo Anker i nā hiʻohiʻona mai 10,000 mAh (37 Wh) a hiki i 25,000 mAh (90 Wh).
Hiki ke hoʻopaʻa hou ʻia nā pāʻani keiki. Nā kaʻa kaʻa mamao, -pāʻani māmā, nā mea hoʻonaʻauao uila. Paʻi mau i ke kūʻai ʻana i nā ʻakika alkaline.
Loaʻa i nā ʻenehana home akamai-Ke kani ʻana i ka bele puka wikiō he pākaukau lithium hiki ke hoʻoneʻe ʻia. Hoʻohana nā kāmela palekana ʻo Arlo i nā pākaukau rechargeable i mau mahina. Loaʻa i nā thermostats Google Nest nā ʻeke lithium backup. Holo nā laka akamai ʻo ʻAukake ma ka lithium AA.
Hiki ke hoʻopiha hou ʻia nā kukui hoʻomaha. Nā kukui kaula me nā ʻaʻa i kūkulu ʻia-i loko a me nā panela lā. Nā ihoiho LED hiki ke hoʻouka hou. Nā mea kāhiko.
ʻOkoʻa nā hihia hoʻohana ʻoihana. Hoʻololi ka poʻe hana hale i nā pila Milwaukee a i ʻole DeWalt i ka lā a pau. Hoʻopi ka hale kūʻai forklift i nā pākahi lithium ion i ka wā hoʻomaha-15 mau minuke manawa e hoʻopaʻa ai i nā beats e kali ana i nā hola e hoʻopaʻa ai nā ʻakika lead-acid.
ʻOi aku ka lohi o ka hoʻohana ʻana i nā mea hana mahiʻai akā ke hana nei. ʻO John Deere e hoʻāʻo ana i nā traktor uila. ʻO nā lopako mahiʻai kūʻokoʻa pinepine uila. Pūnaehana hoʻoheheʻe wai me ka hoʻihoʻi ʻana i ka pākaukau.
Hoʻopili ka ʻoihana hoʻomaʻemaʻe i ka lithium. Hāʻawi nā hui ʻōpala papahele, nā mea ʻoki ʻoki, nā mea holoi ʻauʻau pāʻoihana -e like me Tennant a me Karcher i nā koho lithium. ʻOi aku ka wikiwiki o ka hoʻouka ʻana, ʻoi aku ka māmā o ke kaumaha, ʻaʻohe mālama ʻana i ka wai pākaukau e like me nā ʻōnaehana ʻakika -kahiko.
He aha ka hewa maoli
Hoʻohaʻahaʻa nā pākaukau. ʻAʻole paʻa mau ke kemika. Hoʻopaʻa ka pākaukau lithium ion maʻamau i ka 80% mana ma hope o 500-1000 mau kaʻina hoʻopiʻi, ma muli o ke kemika a me nā ʻano hoʻohana. Hoʻopaʻa ʻo Tesla i kā lākou mau pihi EV no 70% paʻa i 8 mau makahiki / 100,000-150,000 mau mile ma muli o ke kumu hoʻohālike.
ʻOi aku ka wikiwiki o ka hoʻopau ʻana o ka mahana ma mua o kekahi mea. ʻO ka hoʻopaʻa ʻana a i ʻole ka hoʻohana ʻana i nā pila ma luna o 30 degere (86 degere F) e hoʻokē pinepine i ka hoʻohaʻahaʻa. Hoʻemi ke anu i ka hiki no ka manawa lōʻihi akā ʻaʻole e pōʻino mau e like me ka wela. ʻO kēia ke kumu e hoʻohaʻahaʻa wikiwiki ai nā pihi EV Phoenix ma mua o nā ʻāpana Seattle.
He ʻoiaʻiʻo nō hoʻi ka ʻelemakule kalena. E hoʻohaʻahaʻa nā pākaukau me ka noho ʻole ʻana. E mālama iā lākou ma 40-50% ka hoʻoili ʻana i nā mahana anuanu no ka lōʻihi o ke ola ʻana. ʻO ka mālama ʻana i kahi pākaukau ma 100% uku a me 40 degere no nā manawa lōʻihi ka hihia ʻoi loa.
Kakaʻikahi nā hanana palekana akā e hana i nā nūhou ke hana lākou. ʻO nā hemahema o ka hana ʻana i hana ʻia i ke ahi ʻo Samsung Galaxy Note 7 ma 2016-ua hoʻomanaʻo lākou i 2.5 miliona mau kelepona. Ua puhi pinepine ʻia nā Hoverboards i ke ahi i ka makahiki 2015-2016 i pāpā ʻia e nā mokulele. ʻO ka mea maʻamau, pili kēia i ka hana ʻana i nā pilikia hoʻomalu maikaʻi, pōʻino kino, a i ʻole ka hoʻouka ʻana me nā mea hoʻoili hewa.
Holo ka wela -i ka wā e wela ai ke kelepona a ho'āla ka wela i nā hopena hou aʻe e hoʻonui ai i ka wela-ʻo ia ke ʻano hemahema nui. He nui nā hiʻohiʻona palekana i nā ʻōhua i hoʻolālā ʻia: nā kaapuni palena o kēia manawa, nā fuses wela, nā puka hoʻoluhi kaomi, nā papa pani hoʻokaʻawale. Hoʻokuʻu ʻia kēia mau pale ʻana i kēia mau mea pale.
Hoʻopilikia ka pilina i nā mea hoʻohana. Ke hoʻohana nei kēlā me kēia brand mea hana i nā ʻano mea like ʻole. ʻAʻole kūpono nā ʻeke DeWalt i nā mea hana Milwaukee. Maikaʻi ʻo Ryobi i ka mālama ʻana i kā lākou One+ platform i kūpono no nā makahiki-mea hana mai 2005 me nā ʻaniani mai 2025.
Ke hoʻomau nei ke kūkulu hou ʻana i nā ʻōnaehana hana. Li-Cycle, Redwood Materials, a me nā mea ʻē aʻe e kūkulu ana i nā mea kanu hoʻolaʻa pākaukau lithium i hoʻolaʻa ʻia. Hiki iā lākou ke hoʻihoʻi hou i ka 95%+ o nā mea pākaukau. He mea paʻakikī naʻe ka hoʻolele ʻana i nā ʻōpala i ka ʻōpala, ka pilikia o ka waiho ʻana.
Hana nui nā ʻōnaehana hoʻokele pākaukau
He mea koʻikoʻi ka BMS akā ʻike ʻole ʻia. I loko o kahi pona, nānā ʻo ia i kēlā me kēia pūʻulu kelepona, koho i ke koena o ka manawa holo, hoʻomalu i ka nui o ka hoʻouka ʻana, hōʻike i ke olakino pākaukau i ka ʻōnaehana hana. ʻOi aku ka maʻalahi ma mua o ke kani ʻana.
He mea paʻakikī loa ka helu ʻana o ka mokuʻāina-o-. Hoʻopili ʻia ka ʻili uila me ka pae hoʻoili, akā ʻokoʻa ka pilina me ka mahana, ka ukana, ka makahiki pākaukau. Hoʻohana ka BMS maikaʻi i nā algorithms paʻakikī e helu ana i kēia mau mea a pau.
He mea nui ka hoʻokolo ʻana o ke kelepona i loko o nā pūke kelepona lehulehu. Loaʻa nā ʻokoʻa liʻiliʻi o kēlā me kēia pūnaewele. I ka wā o ka hoʻouka ʻana, hiki i kahi BMS ke hoʻohuli i kēia manawa a puni nā cell piha e hiki ai i nā mea nāwaliwali ke hopu. Hoʻopau ʻo Passive Balancing i ka ikehu e like me ka wela. Hoʻololi ka hoʻohālikelike ʻana i ka ikehu ma waena o nā cell, ʻoi aku ka maikaʻi akā ʻoi aku ka pipiʻi.
Hoʻoponopono mahanahana-ka BMS ke nānā nei i ka wela o ke kelepona a hiki ke hoʻemi i ka nui o ka hoʻouka/hoʻokuʻu ʻana inā wela loa nā mea. Loaʻa i nā EV ka hoʻokele wela me ka hoʻoluʻu wai. Pili wale nā mea hana mana i nā ʻoki wela.
Kūkākūkā kamaʻilio-Kūkaʻikaʻi nā pahu BMS i nā mea hoʻokipa me ka hoʻohana ʻana i I2C, SMBus, CAN bus a i ʻole nā kuʻina ponoʻī. Hāʻawi kēia i nā mea hana e hōʻike i ka ʻike pili pono a hoʻopaʻa i ka hana.
Hoʻohui nā noi ʻenehana i ka nānā ʻana i ka pākaukau i nā ʻōnaehana ākea. Hiki i kahi hale kūʻai ke hahai i nā ʻaʻa forklift āpau ma ke kikowaena, ka hoʻonohonoho ʻana i ka hoʻouka ʻana a me ka hae hae ʻana i nā ʻaʻa e pono ai ke pani. Ka mālama wānana ma muli o ka ʻikepili BMS.
He aha ka mea e hiki mai ana ma ka ʻenehana Bati
ʻO nā ʻaʻa paʻa -ʻano paʻa ka grail hemolele. E hoʻololi i ka wai electrolyte me ka keramika paʻa a i ʻole ka polymer. ʻOi aku ka palekana-ʻaʻohe wai wela. Hiki ke ʻoi aku ka nui o ka ikehu. Ua ʻōlelo ʻo Toyota e loaʻa iā lākou nā ʻakika -ʻāina paʻa i nā kaʻa i ka makahiki 2027-2028. QuantumScape, Solid Power, nā mea ʻē aʻe e hoʻomohala ana i ka ʻenehana. Akā ʻaʻole i hoʻoholo ʻia ka hana ʻana ma ka nui.
ʻO nā pākaona sodium-iona e hoʻohana ana i ka paʻakai ma kahi o ka lithium-mea maka haʻahaʻa, hiki ke emi ke kumu kūʻai. Ua hoʻolaha aku ʻo CATL i nā ʻona pāpaʻi sodium -ion i ka makahiki 2021. ʻOi aku ka haʻahaʻa o ka ikehu ma mua o ka lithium ion, akā ʻae ʻia ia no ka mālama paʻa. ʻO ka hana ʻana i ka sodium-ʻo Northvolt ma ʻEulopa.
Hāʻawi ka Lithium-sulfur i ka manaʻo ʻoi aku ka ʻoi aku ka nui o ka ikehu ikehu-a hiki i 500 Wh/kg me 250 Wh/kg no ka lithium ion o kēia manawa. Akā he mea weliweli ke ola pōʻaiapuni, maʻamau ka hoʻohaʻahaʻa ʻana ma hope o 50-100 cycles. Ke hoʻomau nei ka noiʻi.
ʻOi aku ka kiʻekiʻe o nā pākaʻi Lithium-air (lithium-oxygen) -malia he 1,000 Wh/kg. Akā naʻe lākou i ka ʻimi noiʻi laboratory me nā luʻina hana nui.
No nā makahiki he 5-10 e hiki mai ana, e lanakila ana ka ion lithium ma'amau. Ke hoʻomau nei ka hoʻomaikaʻi ʻana i nā mea cathode maikaʻi aʻe, nā anodes silicon e pani ana i ka graphite (hoʻonui i ka mana 20-40%), nā hoʻomaikaʻi ʻana i ke kaʻina hana e hōʻemi ana i nā kumukūʻai.
Ua hāʻule nā kumukūʻai pākaukau ma kahi o 90% mai 2010 a i 2023, mai ka $1,100/kWh a i $130/kWh no nā pā uila EV. Ke hoʻomau nei kēlā ʻano, hiki i ka $ 80-100 / kWh i ka makahiki 2030. Ma kēlā mau kumukūʻai, hiki i nā EV ke kūʻai aku i ka parity me nā kaʻa kinoea me ke kālā ʻole.
ʻO ka hoʻohaʻahaʻa Cobalt kahi mea nui. Loaʻa i ka ʻoihana Cobalt nā kuleana kanaka a me nā pilikia o ke kaulahao hoʻolako. Hoʻohana liʻiliʻi nā ʻeke NMC o kēia wā ma mua o nā hana kahiko (NMC 811 he 80% nickel, 10% manganese, 10% cobalt versus mua 1:1:1 ratios). ʻAʻole loaʻa i nā pākahiko LFP ka cobalt.
Ke kūʻai ʻia nei nā anodes silikon i kēia manawa. Hāʻawi ʻo Sila Nanotechnologies i nā mea anode silika i nā mea hana he nui. Ua hoʻolaha ʻo Panasonic i nā pākahi anode silicon no ka hana ʻana. Ke hoʻohana nei ʻo Tesla i kekahi mau silika i kā lākou mau cell. Hoʻonui kēia i ka mana 10-20% me ka hoʻololi ʻole i kekahi mea e pili ana i ka pākaukau.
ʻO ka nīnau "he aha nā ʻāpana lithium ion" e loaʻa i kahi pane ʻoi aku ka lōʻihi i loko o ʻelima mau makahiki. ʻO nā ʻano huahana hou aʻe e hele ana i ka uila. Nā noi hou aku kahi e hoʻoneʻe ai ka lithium ion i nā ʻenehana kahiko. Ua oo koke ka ʻenehana akā e hoʻomaikaʻi mau ana.
ʻOi aku ka nui o ka hoʻomaopopo ʻana i nā mea hana e hoʻohana ai i nā pā lithium i ka wā e hōʻiliʻili ai mākou i nā mea he nui. ʻO ka hapa nui o nā hale i kēia manawa he 20-50 mau mea hiki ke hoʻouka hou. ʻO ka ʻike i kāu mea i loaʻa, pehea e mālama ai, a me ka wā e hoʻololi ai e hoʻolōʻihi i kēlā mau hoʻopukapuka a ʻoi aku ka maikaʻi.
