He aha ka lithium-ion electrode slitting?
Nā Kaʻina Electrode Slitting
Kapa ʻia ka ʻoki ʻoki ʻana ma ka hana ʻenekinia, a e like me ke ʻano o nā mea hana ʻoki, hiki ke hoʻokaʻawale ʻia i nā ʻano ʻako e like me ka ʻako -blade, ʻāhi paʻa-lau, ʻako ʻōniʻoniʻo (a ʻoki ʻōwili ʻia paha), a me ka ʻako ʻōpala.
I ka ʻako ʻaoʻao -lau, aia kahi kihi paʻa ma waena o ka ʻaoʻao o luna a me lalo, a ʻo ka huina hoʻi ma ke ʻano he 1 degere ~ 6 degere. ʻO ka mea maʻamau, ua hili ka ʻaoʻao luna, e like me ka hōʻike ʻana ma ke Kiʻi 7-2(a). No ka mea, ʻaʻole like nā ʻaoʻao o luna a me lalo, aia ka ikaika ma ka ʻaoʻao o ka ʻoki ʻana, e maʻalahi ke hoʻololi i ka ʻoki ʻoki. Eia naʻe, liʻiliʻi ka ʻāpana ʻako, a ʻoi aku ka liʻiliʻi o ka ikaika ʻako a me ka hoʻohana ʻana i ka ikehu ma mua o ka ʻako ʻako palahalaha, no laila ua hoʻohana ʻia ia no ka ʻako ʻana i nā papa mānoanoa i nā mīkini ʻako nui a me ka nui, ʻaʻole i hoʻohana ʻia no ka ʻoki uila.
Ua like ke ano o ka wili lau -palahalaha me ka oblique-lau, koe nae ka like ana o na aoao o luna a me lalo, e like me ia i hoikeia ma ke Kii 7-2(b). Loaʻa ia i ka ʻoki ʻana me ka ʻoki ʻole a maikaʻi ka maikaʻi o ka ʻoki ʻana, akā nui ka ikaika o ka shearing, a hoʻohana nui ʻia i nā mīkini ʻoki liʻiliʻi a no ka hoʻopaʻa ʻana i nā papa lahilahi a me nā kiʻiʻoniʻoni [1-2], a me ka ʻokiʻoki electrode.
Ua kapa ʻia ʻo ka ʻaʻa ʻāwili ʻana arc-edge roll cutting, e hoʻohana ana i nā mea paahana me ka -arc. Hoʻopau nā mea hana i ke kaʻina ʻako ʻako ma ka ʻōwili ʻana a me ka ʻōwili ʻana i ʻelua koʻi paʻa paʻa, e like me ka hōʻike ʻana ma ke Kiʻi 7-2(c). Hoʻohana nui ia no ka ʻoki ʻana i ka ʻoki kea - lōʻihi paʻa, ka ʻoki ʻana i ke poʻo a me ka huelo, a me ka ʻoki ʻana. ʻO ka maʻamau, i ka wā e ʻohi ai i nā papa waena a me ka mānoanoa, loaʻa iā ia ke ʻano kiʻekiʻe, ka hoʻohana haʻahaʻa haʻahaʻa, ke ola lōʻihi, a me nā huahana kiʻekiʻe[3].
Hoʻopau ʻia ka ʻohi puʻupuʻu ma ka ʻōwili mau ʻana o ʻelua huila ʻokiʻoki ʻano diski, hoʻokahi ma luna a hoʻokahi ma lalo, e like me ka hōʻike ʻana ma ke Kiʻi 7-3. I ka wā ʻako, komo ka pepa electrode uncoiled i ka wehe ʻoki diski a māhele ʻia i mau ʻāpana he nui ma hope o ka ʻoki ʻana[1]. Hoʻohana nui ʻia ka ʻāhi diski no ka ʻoki ʻana i ka lōʻihi o nā papa lahilahi, nā kiʻiʻoniʻoni lahilahi, a me nā pahu metala.
I ka hana 'ana i nā 'akika lithium-ion, 'o ka 'oki lō'ihi (slitting) o nā pepa electrode e ho'ohana ma'amau i ka ako diski, a'o ka 'oki -kea e ho'ohana i ka-blade shearing. Hana nā laina hana ʻakomi i ka ʻoki ʻana ma mua, a laila ke ʻoki -ʻoki. ʻO ka mea maʻamau, ua kau ʻia nā koi ma luna o ka ʻoki ʻana o nā pā uila uila lithium-ion:
① ʻO ke kiko kiʻekiʻe o ka pepa electrode;
② ʻO nā ʻaoʻao o ka ʻaoʻao electrode he palahalaha a ʻaʻohe burrs, me ka liʻiliʻi o nā hemahema, a ʻaʻole i pohō ka papa pani electrode;
③ ʻO ka hua kiʻekiʻe a me ka hana kiʻekiʻe.
Kaʻina ʻāhi Pepa Electrode
No nā mea palaki, hiki ke hoʻokaʻawale ʻia ke kaʻina ʻāhi i ʻekolu mau ʻanuʻu[5-6]:
① Hoʻomaka ka lau e kaomi i loko o ka pā, a ʻo ka mea pā ma waena o nā ʻoki e hoʻoheheʻe ʻia a kahe a hiki i ka nui o ka deformation plastic i ka palena o ka palaka. Kapa ʻia kēia ka pae mua. I loko o kēia kaʻina, ʻako ʻia ka mea pāpaʻi, e hana ana i kahi ʻili ʻili maʻemaʻe, e ʻike i ke Kiʻi 7-4(a).
② Ke hoʻomau nei ka pahi i ka paʻi ʻana i loko o ka pā, a nahā ka nucleate, hoʻolaha, a komo i loko o ka mea pā ma waena o nā ʻoki. ʻO ka mea pā ma waena o nā ʻokiʻoki e haehae ʻia ma lalo o ka hana o ke koʻikoʻi tensile a hiki i ka ʻaoʻao o luna a me lalo ma ka mokulele hoʻokahi. Kapa ʻia kēia ʻo ka pae ʻelua. I kēia pae, ua haehae ʻia ka mea pā, e hana ana i kahi ʻili haʻihaʻi, e ʻike i nā Kiʻi 7-4(b) a me (c);
③ Ke hoʻomau nei ka pahi i lalo. Ma muli o ke kahe ʻana o ka plastic, ua hoʻokuʻu ʻia ka mea pā ma waena o nā ʻoki i loko o kahi āpau liʻiliʻi kahi e uhi ai nā lau. I ka piʻi ʻana o ka ʻoki ʻana o ka maka, ua haehae ʻia a huki ʻia ka mea pā i loko o ke āpau, e hana ana i nā burrs ma ka ʻaoʻao, e ʻike i ke Kiʻi 7-4(d), a kaʻawale nā mea hana. Kapa ʻia kēia ʻo ke kahua hoʻokumu burr. I ka wā o ka hoʻokaʻawale ʻana i ka mea hana, e loaʻa i nā mea hana kahi hopena maʻalahi a extruding paha i ka mea pā, e hoʻololi ai i ka morphology o ka ʻili haʻihaʻi a me nā burrs, akā liʻiliʻi ka loli.
Hōʻike ʻia ka ʻāpana kea -shear ma hope o ka ʻoki ʻana ma ke Kiʻi 7-5, aia ʻekolu ʻāpana: ʻo ka ʻili ʻili maʻemaʻe, ka ʻili haʻi haʻihaʻi, a me ke kāʻei [5-6]. Kapa ʻia ka ʻili haʻihaʻi ʻeleʻele ka ʻili haʻihaʻi. Pili kona laula i ka plasticity o ka mea. No nā mea me ka plasticity ʻoi aku ka liʻiliʻi, ʻoi aku ka liʻiliʻi o ka ʻili haʻihaʻi, ʻoi aku ka nui o ka ʻili kuʻi maʻemaʻe, a ʻoi aku ka nui o ke kahe metala, ʻoi aku ka maʻalahi o nā burr. ʻO ka mea ʻē aʻe, no nā mea palupalu, ʻaʻohe ʻili ʻili maʻemaʻe.
