Kupu Whakataki：
Ngā pākahiko lithium ternary mengā pākahiko phosphate rino lithiumKo ngā momo matua e rua o ngā pākahiko lithium e whakamahia whānuitia ana i roto i ngā waka hiko, ngā pūnaha rokiroki pūngao me ētahi atu taputapu hiko. Engari kua mārama koe ki ō rātou āhuatanga me ngā rerekētanga? He rerekē rawa te hanganga matū, ngā āhuatanga mahi me ngā mara tono. Me ako atu tātou mō rātou me Heltec.
Te hanganga rauemi:
Pūhiko lithium tuatoru: Ko te rauemi hiko pai ko te nikara, te konutai, te konupora waikura (NCM) te nikara, te konutai konumohe waikura (NCA) rānei, he mea tito mai i te nikara, te konutai, te konupora, te nikara rānei, te konutai, te konumohe me ētahi atu waikura konganuku, ā, ko te hiko kino ko te karāpeti. I roto i ēnei, ka taea te whakarite i te ōwehenga o te nikara, te konutai, te konupora (te konumohe rānei) kia rite ki ngā hiahia tūturu.
Pūhiko phosphate rino lithium: ka whakamahia te phosphate rino lithium (LiFePO₄) hei rauemi hiko pai, ā, ka whakamahia hoki te graphite mō te hiko kino. He pumau te hanganga matū o tēnei mea, ā, kāore he konganuku taumaha me ngā konganuku onge i roto, he pai ake mō te taiao.
Te mahi utu me te tukunga:
Pūhiko lithium tuatoru: he tere te utu me te tukunga, ka taea te urutau ki te utu me te tukunga o te iahiko teitei, he pai mō ngā taputapu me ngā horopaki he nui ngā whakaritenga mō te tere utu, pērā i ngā waka hiko e tautoko ana i te utu tere. I roto i te taiao pāmahana iti, he pai hoki te mahi utu me te tukunga, ā, he iti noa te ngaronga o te kaha.
Pūhiko phosphate rino lithiumHe puhoi te tere o te utu me te tukunga, engari he pumau te mahi utu me te tukunga huringa. Ka taea e ia te tautoko i te utu tere teitei, ā, ka taea te utu katoa i roto i te 1 hāora te tere rawa, engari ko te pai o te utu me te tukunga he tata ki te 80%, he iti ake i te pākahiko lithium tuatoru. I raro i ngā āhuatanga pāmahana iti, ka tino heke te mahi, ā, ko te tere pupuri kaha o te pākahiko he 50%-60% noa iho.
Te mātotoru o te pūngao:
Pūhiko lithium toru: He tino teitei te kaha o te pūngao, neke atu i te 200Wh/kg, ā, ko ētahi hua matatau ka neke atu i te 260Wh/kg. Mā tēnei ka taea e ngā pākahiko lithium toru te penapena i te kaha ake i te rahinga kotahi, i te taumaha kotahi rānei, ka roa ake te tawhiti taraiwa mō ngā taputapu, pērā i ngā waka hiko, ka taea te tautoko i ngā waka ki te haere i ngā tawhiti roa.
Pūhiko phosphate rino lithium: He iti noa te mātotoru o te pūngao, tata ki te 110-150Wh/kg. Nō reira, kia rite te whānuitanga taraiwa ki ngā pūhiko lithium tuatoru, me nui ake te rahinga, te taumaha rānei o ngā pūhiko phosphate rino lithium.
Te ora o te huringa:
Pūhiko lithium tuatoru: He poto noa te roa o te huringa, ā, ko te maha o ngā huringa ā-ture he tata ki te 2,000 ngā wā. I te whakamahinga tūturu, tera pea kua heke te kaha ki te 60% i muri i te 1,000 huringa. Mā te whakamahinga hē, pērā i te utu nui rawa, te whakakorenga rānei, me te whakamahinga i roto i ngā taiao pāmahana teitei, ka tere ake te pirau o te pūhiko.
Pūhiko phosphate rino lithium: He roa te ora o te huringa, neke atu i te 3,500 ngā huringa utu me te tuku, ā, ko ētahi pākahiko kounga teitei ka eke ki te neke atu i te 5,000 ngā wā, he rite ki te neke atu i te 10 tau o te whakamahinga. He pai te pumau o te whatunga, ā, he iti noa te pānga o te whakaurunga me te tango i ngā katote lithium ki te whatunga, ā, he pai te hurihanga.
Haumaru:
Pūhiko lithium tuatoru: he ngoikore te pumau o te wera, he ngāwari ki te puta he rerenga wera i raro i te pāmahana teitei, te uta nui, te ara iahiko poto me ētahi atu āhuatanga, ka hua ake he mōrearea nui o te mura, te pahū rānei. Heoi, me te whanaketanga o te hangarau me te whakapakari ake i ngā mahi haumaru, pēnei i te whakamahinga o ngā pūnaha whakahaere pūhiko matatau ake me te arotautanga o te hanganga pūhiko, kei te whakapai tonu hoki tōna haumaru.
Pūhiko phosphate rino lithium: he pai te pumau o te wera, he uaua te tuku hāora i te pāmahana teitei o te rauemi hiko pai, ā, e kore e tīmata te pirau tae noa ki te 700-800℃, ā, e kore e tuku i ngā ngota hāora ina pāngia e te pānga, te poka, te ara iahiko poto me ētahi atu āhuatanga, ā, kāore e ngāwari ki te mura kino, he pai te mahi haumaru.
Utu:
Pūhiko lithium toru: nā te mea he nui ngā konganuku utu nui pērā i te nikara me te konupora kei roto i te rauemi hiko pai, ā, he nui ngā whakaritenga mō te tukanga whakaputa, ā, he kaha ake hoki ngā whakaritenga mō te taiao, nō reira he tino teitei te utu.
Pūhiko phosphate rino lithiumHe iti te utu o ngā rauemi mata, he māmā noa te tukanga whakaputa, ā, he pai ngā painga o te utu whānui. Hei tauira, i roto i ngā waka hiko hou, he iti te utu o ngā tauira e mau ana i ngā pākahiko rino phosphate lithium.
Whakamutunga
Ko te whiriwhiri i te pākahiko e whakawhirinaki ana ki ngā whakaritenga motuhake o te tono. Mena he nui ake te kaha o te pūngao me te roa o te ora o te pākahiko, he pai ake pea ngā pākahiko lithium ternary; mena ko te haumaru, te pakari me te roa o te ora ngā mea matua, he pai ake ngā pākahiko lithium rino phosphate.
