Pehea ka hana ʻana o nā Bateri Lithium-ion?

Hiki i nā ʻona Lithium-ion ke ola i nā miliona o nā kānaka i kēlā me kēia lā.Mai nā laptops a me nā kelepona hele i nā hybrids a me nā kaʻa uila, ke ulu nei kēia ʻenehana ma muli o kona kaumaha māmā, kiʻekiʻe o ka ikehu, a me ka hiki ke hoʻihoʻi.

No laila pehea e hana ai?

Ke hele nei kēia animation iā ʻoe ma ke kaʻina hana.

NA KUMU

Hana ʻia kahi pākaukau me kahi anode, cathode, separator, electrolyte, a me ʻelua mau mea hōʻiliʻili o kēia manawa (maikaʻi a maikaʻi ʻole).Mālama ka anode a me ka cathode i ka lithium.Lawe ka electrolyte i nā ion lithium i hoʻopiʻi maikaʻi ʻia mai ka anode a i ka cathode a me ka hope ma o ka mea hoʻokaʻawale.ʻO ka neʻe ʻana o nā ion lithium e hana i nā electrons manuahi i loko o ka anode e hana i ka uku ma ka ʻohi ʻohi maikaʻi.A laila, kahe ke au uila mai ka ʻohi o kēia manawa ma o kahi mea hana e hoʻohana ʻia (kelepona, kamepiula, a me nā mea ʻē aʻe) i ka ʻohi o kēia manawa ʻino.Hoʻopaʻa ka mea hoʻokaʻawale i ke kahe o nā electrons i loko o ka pākaukau.

KA HOʻOPIʻI

ʻOiai e hoʻokuʻu ana ka pākaukau a hāʻawi i kahi au uila, hoʻokuʻu ka anode i nā ion lithium i ka cathode, e hana ana i ke kahe o nā electrons mai kekahi ʻaoʻao a i kekahi.Ke hoʻopili nei i ka hāmeʻa, ʻokoʻa ka hopena: Hoʻokuʻu ʻia nā ion Lithium e ka cathode a loaʻa i ka anode.

IKEA NUI VS.POWER DENSITY ʻO nā manaʻo maʻamau ʻelua e pili ana i nā pila, ʻo ia ka nui o ka ikehu a me ka nui o ka mana.Ana ʻia ka nui o ka ikehu i nā hola-watt no ka kilo (Wh/kg) a ʻo ia ka nui o ka ikehu e hiki ai i ka pākaukau ke mālama e pili ana i kona nuipaʻa.Ana 'ia ka mana i loko o watts no kilo (W/kg) a 'o ia ka nui o ka mana i hiki ke hana 'ia e ka pila e pili ana i kona nuipa.No ke kahakiʻi ʻana i kahi kiʻi maʻalahi, e noʻonoʻo e hoʻokahe i kahi wai.Ua like ka nui o ka ikehu me ka nui o ka loko, oiai ua like ka ikaika o ka mana me ka hookahe i ka wai i ka hikiwawe loa.Ke hana nei ke Keʻena ʻenehana kaʻa i ka hoʻonui ʻana i ka nui o ka ikehu o nā pila, ʻoiai e hōʻemi ana i ke kumukūʻai, a me ka mālama ʻana i ka mana mana e ʻae ʻia.No ka ʻike hou aku i ka pākaukau, pls e kipa:
