Ma hea:

He aha ka hana inā kiʻekiʻe loa ka paʻakai o kēia manawa?
ʻO ka nui o ka nui o kēia manawa ke kumu i nā mīkini hāʻule nui ma muli o ka ʻōnaehana. I loko o nā ʻakika, hoʻoulu ʻia ka pāpaʻi lithium kiʻekiʻe ma luna o nā anodes, ka hana dendrite i hiki ke hoʻokaʻawale i nā mea hoʻokaʻawale, ka hoʻonui ʻana i ka paʻa -electrolyte interphase ulu, a me ka haʻihaʻi electrode mai ke kaumaha mechanical.

Hiki ke ʻinoʻino ka nui o kēia manawa?
ʻAe, hiki ke ʻinoʻino ka nui o kēia manawa ma ka manaʻo makemakika, e hōʻike ana i ke kahe o kēia manawa ma ka ʻaoʻao ʻē aʻe.

He aha ka manaʻo kiʻekiʻe o kēia manawa?
"High" current density is application-dependent and relates to material limits. For lithium-ion batteries, >Manaʻo ʻia ʻo 300 mA/cm² kiʻekiʻe a ʻoi aku ka wikiwiki o ka hoʻohaʻahaʻa ʻana.
