ʻO ka haku mele ʻana opākahi lithium

ʻO ka hoʻokumu ʻana o nā ʻenehana lithium ka nui o nā mea electrode maikaʻi, nā mea electrode maikaʻi ʻole, nā mea hoʻokaʻawale, nā electrolytes, a me nā pahu.

1. Ma waena o nā mea electrode maikaʻi, nā mea i hoʻohana pinepine ʻia he lithium cobaltate, lithium manganate, lithium iron phosphate a me nā mea ternary (polymers of nickel, cobalt and manganese).ʻO nā mea electrode maikaʻi e pili ana i kahi hapa nui (ʻo ka nui o ka nui o nā mea electrode maikaʻi a maikaʻi ʻole ʻo 3: 1 ~ 4: 1), no ka mea, ʻo ka hana o ka mea electrode maikaʻi e pili pono i ka hana o ka pā lithium-ion, a ʻo kona kumukūʻai hoʻi e hoʻoholo pololei i ke kumukūʻai o ka pākaukau.
2. Ma waena o nā mea electrode maikaʻi ʻole, graphite kūlohelohe a me ka graphite artificial i kēia manawa nā mea electrode maikaʻi ʻole.ʻO nā mea anode e ʻimi ʻia nei he nitrides, polyaspartic acid, tin-based oxides, tin alloys, nano-anode materials, a me nā pūhui intermetallic ʻē aʻe.E like me kekahi o nā mea nui ʻehā o nā pā lithium, ʻo nā mea electrode maikaʻi ʻole he kuleana koʻikoʻi i ka hoʻomaikaʻi ʻana i ka nui o ka pākaukau a me ka hana pōʻai, a aia ma ke kumu o ka waena waena o ka ʻoihana pākaukau lithium.
3. ʻO nā mea hana diaphragm e pili ana i ka mākeke he polyolefin diaphragms, i hana nui ʻia me ka polyethylene a me ka polypropylene.I loko o ke ʻano o ka mea hoʻokaʻawale pākahi lithium, ʻo ka mea hoʻokaʻawale kekahi o nā mea nui o loko.Hoʻoholo ka hana o ka mea hoʻokaʻawale i ke ʻano o ka interface a me ke kūpaʻa kūloko o ka pākaukau, e pili pono ana i ka hiki, ka pōʻai a me ka hana palekana o ka pā.He mea koʻikoʻi ka mea hoʻokaʻawale me ka hana maikaʻi loa i ka hoʻomaikaʻi ʻana i ka hana holoʻokoʻa o ka pākaukau.
4. Hana ʻia ka electrolyte me nā mea hoʻoheheʻe organik maʻemaʻe kiʻekiʻe, nā paʻakai lithium electrolyte, nā mea hoʻohui pono a me nā mea waiwai ʻē aʻe i kekahi māhele ma lalo o kekahi mau kūlana.Hoʻokani ka electrolyte i ka hana o ke alakaʻi ʻana i nā ion ma waena o nā electrodes maikaʻi a maikaʻi ʻole o ka pā lithium, ʻo ia ka mea e hōʻoiaʻiʻo ai i ka volta kiʻekiʻe a me ka ikehu kiʻekiʻe o ka pā lithium ion.
5. ʻO ka pahu pahu: hoʻokaʻawale ʻia i ka pahu kila, ka pahu alumini, ka pahu hao nickel-plated (no nā pahu cylindrical), kiʻi ʻoniʻoni alumini-plastic (paʻi palupalu), a me nā mea ʻē aʻe, a me ka pāpale pākahi, ʻo ia hoʻi nā hopena maikaʻi a maikaʻi ʻole o ka pākaukau
6. ʻO ke kumu o ka hana ʻana i ka Batri
7. Ke hoʻopiʻi ʻia ka pākaukau, hana ʻia nā ion lithium ma ka electrode maikaʻi o ka pākaukau, a neʻe nā ion lithium i hana ʻia i ka electrode maikaʻi ʻole ma o ka electrolyte.ʻO ka hana kalapona o ka electrode maikaʻi ʻole he nui nā pores, a ua hoʻokomo ʻia nā ion lithium i hiki i ka electrode maikaʻi ʻole i loko o nā micropores o ka papa kalapona.ʻOi aku ka nui o nā ion lithium i hoʻokomo ʻia, ʻoi aku ka kiʻekiʻe o ka hiki ke hoʻopiʻi.ʻOi aku ka nui o nā ion lithium e hoʻi i ka electrode maikaʻi, ʻoi aku ka kiʻekiʻe o ka hiki ke hoʻokuʻu.ʻO ka'ōlelo maʻamau,ʻo ka mana hoʻokuʻu e pili ana i ka hoʻokuʻuʻana.Inā hoʻohālikelike ʻia ke kiʻi o ka pākaukau lithium me kahi noho ʻōluli, ʻo nā ʻaoʻao ʻelua o ka noho pōhaku nā electrodes maikaʻi a maikaʻi ʻole o ka pākaukau, a ʻo nā ion lithium e like me nā mea pāʻani, e holo ana i hope a i waena o nā ʻaoʻao ʻelua o ka noho pōhaku. .No laila, ua kapa ʻia nā pākahi lithium he mau ʻona noho pōhaku.
