He aha ka meahao litiumapākahiko? Hoʻolauna i ke kumumanaʻo hana a me nā pono o ka pākahiko hao lithium

ʻO ka pākahiko hao Lithium kahi ʻano pākahiko i loko o ka ʻohana pākahiko lithium. ʻO kona inoa piha ʻo lithium iron phosphate lithium ion battery. ʻO ka mea cathode ka lithium iron phosphate. No ka mea kūpono loa kāna hana no nā noi mana, ua kapa ʻia hoʻi ʻo "lithium iron power battery". (ma hope aku nei i kapa ʻia ʻo "lithium iron battery")

ʻO ke kumumanaʻo hana o ka pākahiko hao lithium (LiFePO4)
ʻO ke ʻano kūloko o ka pākahiko LiFePO4: ʻO LiFePO4 me ke ʻano olivine ma ka hema e hoʻohana ʻia ma ke ʻano he pou maikaʻi o ka pākahiko, kahi i hoʻopili ʻia e ka pepa alumini a me ka pou maikaʻi o ka pākahiko. Ma waenakonu he diaphragm polymer, kahi e hoʻokaʻawale ai i ka pou maikaʻi mai ka pou maikaʻi ʻole. Eia naʻe, hiki i ka lithium ion Li+ ke hele ma waena akā ʻaʻole hiki i ka uila e-. Ma ka ʻākau ʻo ka pou maikaʻi ʻole o ka pākahiko i haku ʻia me ke kalapona (graphite), kahi i hoʻopili ʻia e ka pepa keleawe a me ka pou maikaʻi ʻole o ka pākahiko. Aia ka electrolyte o ka pākahiko ma waena o nā wēlau o luna a me lalo o ka pākahiko, a ua sila ʻia ka pākahiko e kahi pūpū metala.

Ke hoʻopiha ʻia ka pākahiko LiFePO4, neʻe ka lithium ion Li+ i loko o ka electrode maikaʻi i ka electrode maikaʻi ʻole ma o ka membrane polymer; I ka wā o ke kaʻina hana hoʻokuʻu, neʻe ka lithium ion Li+ i loko o ka electrode maikaʻi ʻole i ka electrode maikaʻi ma o ka diaphragm. Ua kapa ʻia ka pākahiko Lithium-ion ma muli o ka neʻe ʻana o nā ion lithium i ka wā e hoʻouka ai a hoʻokuʻu ana.

Ka hana nui o ka pila LiFePO4
ʻO ke anakahi uila maʻamau o ka pākahiko LiFePO4 he 3.2 V, ʻo ke anakahi uila hoʻopiʻi hope he 3.6 V, a ʻo ke anakahi uila hoʻokuʻu hope he 2.0 V. Ma muli o ke ʻano like ʻole a me ke kaʻina hana o nā mea electrode maikaʻi a maikaʻi ʻole a me nā mea electrolyte i hoʻohana ʻia e nā mea hana like ʻole, e ʻokoʻa iki kā lākou hana. No ka laʻana, ʻokoʻa loa ka mana o ka pākahiko o ke kumu hoʻohālike like (pākaukau maʻamau i loko o ka pūʻolo like) (10% ~ 20%).

Nā Pōmaikaʻi opākahiko hao lithium
Ke hoʻohālikelike ʻia me nā pila alakaʻi-acid kuʻuna, loaʻa i nā pila lithium-ion nā pono koʻikoʻi i ka volta hana, ka nui o ka ikehu, ke ola pōʻaiapuni, a pēlā aku. Ke hoʻohālikelike ʻia me ka pila alakaʻi-acid kuʻuna, loaʻa iā ia nā pono penei: ka nui o ka ikehu, ka palekana ikaika, ka hana wela kiʻekiʻe maikaʻi, ka mana kiʻekiʻe, ke ola pōʻaiapuni lōʻihi, ke kaumaha māmā, ka mālama ʻana i ke kumukūʻai hoʻoikaika lumi mīkini, ka liʻiliʻi, ke ola pila lōʻihi, ka palekana maikaʻi, a pēlā aku.
