Te rere wera o te pākahiko lithium-ion me te tātari rauemi

I ēnei rā, he maha ngā kamupene waka e whakamahi ana i ngā pākahiko lithium i roto i ngā pākahiko hiko i runga i te tauine nui, ā, kei te piki haere te kiato o te pūngao, engari kei te mau tonu te āwangawanga o te tangata mō te haumaru o ngā pākahiko hiko, ā, ehara i te otinga pai mō te haumaru o ngā pākahiko. Ko te rere wera te kaupapa rangahau matua mō te haumaru o ngā pākahiko hiko, ā, he mea tika kia arotahi atu ki tēnei.

Tuatahi, kia mārama tātou he aha te rerenga wera. Ko te rerenga wera he āhuatanga tauhohenga mekameka e whakaohohia ana e ngā momo whakaoho, ka hua ake he nui te wera me ngā hau kino e tukuna ana e te pākahiko i roto i te wā poto, ka taea hoki e te pākahiko te mura me te pahū i roto i ngā take kino. He maha ngā take mō te putanga mai o te rerenga wera, pērā i te wera nui, te utu nui rawa, te ara iahiko poto o roto, te tukinga, me ētahi atu. Ko te rerenga wera o te pākahiko ka tīmata mai i te pirau o te kiriata SEI kino i roto i te pūtau pākahiko, ā, muri iho ko te pirau me te rewa o te diaphragm, ka hua ake te irahiko kino me te electrolyte, ā, muri iho ko te pirau o te irahiko pai me te electrolyte, ka puta he ara iahiko poto o roto nui, ka wera te electrolyte, ka horapa ki ētahi atu pūtau, ka puta he rerenga wera nui, ā, ka taea e te pākahiko katoa te whakaputa i te mura ohorere.

Ka taea te wehewehe i ngā take o te rerenga wera ki ngā take o roto me ngā take o waho. Ko ngā take o roto he maha ngā wā nā ngā ara iahiko poto o roto; ko ngā take o waho he maha ngā wā nā te whakamahi kino o ngā mīhini, te whakamahi kino o te hiko, te whakamahi kino o te wera, me ētahi atu.

Ko te ara iahiko poto o roto, arā, he hononga tika i waenga i ngā pito pai me ngā pito kino o te pākahiko, he rerekē rawa te nui o te hononga me te tauhohenga i puta i muri mai. Ko te tikanga, ko te ara iahiko poto nui o roto i puta mai i te whakamahinga kino o te miihini me te wera ka puta tika te rerenga wera. He rerekē, ko ngā ara iahiko poto o roto e puta ake ana i a rātou anō he iti noa iho, ā, he iti rawa te wera e puta mai ana, kāore e puta tonu te rerenga wera. Ko te whanaketanga whaiaro o roto ko ngā hapa hanga, te hekenga o ngā āhuatanga rerekē i puta mai i te koroheketanga o te pākahiko, pērā i te pikinga o te ātete o roto, ngā putunga konganuku lithium i puta mai i te whakamahinga kino mō te wā roa, me ētahi atu. I te roanga o te wā, ka piki haere te mōrearea o te ara iahiko poto o roto i puta mai i aua take o roto.

Ko te tukino ā-mīhini, e pā ana ki te whakarerekētanga o te monomer pākahiko lithium me te kete pākahiko i raro i te mahi a te kaha o waho, me te nekehanga whanaunga o ngā wāhanga rerekē o ia anō. Ko ngā āhua matua ki te pūtau hiko ko te tukinga, te whakaputa me te wero. Hei tauira, ko te pā o tētahi mea ke ki te waka i te tere tiketike i arahi tika ki te hinganga o te diaphragm o roto o te pākahiko, ā, i puta ai he ara iahiko poto i roto i te pākahiko, ā, i puta ai te mura ohorere i roto i te wā poto.

Ko te whakamahinga kino o ngā pākahiko lithium ko te ara iahiko poto o waho, te utu nui, te tukunga nui, me ētahi momo, ka tino whanake pea hei rerenga wera ki te utu nui. Ka puta te ara iahiko poto o waho ina honoa ngā ara iahiko e rua me te pēhanga rerekē ki waho o te pūtau. Ko ngā ara iahiko poto o waho i roto i ngā kete pākahiko ka puta mai i te whakarerekētanga i puta mai i ngā tukinga waka, te rumaki wai, te poke o te ara iahiko, te ru hiko rānei i te wā tiaki. I te nuinga o te wā, ko te wera e tukuna ana mai i te ara iahiko poto o waho kāore e whakamahana i te pākahiko, engari he poka. Ko te hononga nui i waenga i te ara iahiko poto o waho me te rerenga wera ko te pāmahana e tae ana ki te wāhi wera nui. I te wā e kore e taea te whakamarara pai i te wera e puta mai ana i te ara iahiko poto o waho, ka piki te pāmahana o te pākahiko, ā, ka puta te rerenga wera i te pāmahana teitei. Nō reira, ko te tapahi i te iahiko ara iahiko poto, te whakamarara rānei i te wera nui, he huarahi hei aukati i te ara iahiko poto o waho kia kore ai e puta he kino atu. Ko te utu nui, nā te mea he nui te kaha, ko tētahi o ngā tūponotanga nui o te whakamahinga kino hiko. Ko te whakaputanga wera me te hau he āhuatanga noa e rua o te tukanga utu nui. Ka puta te whakaputanga wera mai i te wera ohmic me ngā tauhohenga taha. Tuatahi, ka tipu ngā dendrite lithium ki te mata o te anode nā te nui rawa o te whakauru o te lithium.
