He aha te mearino lithiumpākahiko? He kupu whakataki ki te kaupapa mahi me ngā painga o te pākahiko rino lithium

Ko te pākahiko rino lithium he momo pākahiko nō te whānau pākahiko lithium. Ko tōna ingoa katoa ko te pākahiko rino lithium phosphate lithium ion. Ko te rauemi cathode he lithium rino phosphate. Nā te mea he tino pai tana mahi mō ngā tono hiko, ka kiia hoki ko te "pūhiko mana rino lithium". (e kiia nei i muri nei ko te "pūhiko rino lithium")

Te kaupapa mahi o te pākahiko rino lithium (LiFePO4)
Hanganga ā-roto o te pākahiko LiFePO4: Ko te LiFePO4 me te hanganga olivine i te taha maui e whakamahia ana hei pou pai o te pākahiko, e honoa ana e te pepa konumohe me te pou pai o te pākahiko. Kei waenganui he diaphragm polymer, e wehe ana i te pou pai mai i te pou kino. Heoi, ka taea e te lithium ion Li+ te haere engari kāore e taea e te hiko e-. Kei te taha matau ko te pou kino o te pākahiko he mea hanga ki te waro (graphite), e honoa ana e te pepa parahi me te pou kino o te pākahiko. Kei waenganui i ngā pito o runga me raro o te pākahiko te electrolyte o te pākahiko, ā, kua hiritia te pākahiko e te anga whakarewa.

Ina utua te pākahiko LiFePO4, ka heke te katote lithium Li+ i roto i te irahiko pai ki te irahiko kino mā te kiriuhi pūmua; i te wā o te tukunga, ka heke te katote lithium Li+ i roto i te irahiko kino ki te irahiko pai mā te diaphragm. Ko te ingoa o te pākahiko lithium-ion i muri i te hekenga o ngā katote lithium i te wā e utu ana, e whakakore ana hoki.

Te mahi matua o te pākahiko LiFePO4
Ko te ngaohiko ingoa o te pākahiko LiFePO4 he 3.2 V, ko te ngaohiko utu mutunga he 3.6 V, ā, ko te ngaohiko tukunga mutunga he 2.0 V. Nā te kounga me te tukanga rerekē o ngā rauemi irahiko pai me te kino me ngā rauemi irahiko e whakamahia ana e ngā kaihanga rerekē, ka rerekē te mahi a ēnei rauemi. Hei tauira, he tino rerekē te kaha o te pākahiko o te tauira kotahi (te pākahiko paerewa i roto i te kete kotahi) (10%~20%).

Ngā Painga opākahiko rino lithium
Ki te whakatauritea ki ngā pākahiko waikawa-mata tuku iho, he nui ngā painga o ngā pākahiko lithium-ion i roto i te ngaohiko mahi, te kiato pūngao, te roa o te huringa, me ētahi atu. Ki te whakatauritea ki te pākahiko waikawa-mata tuku iho, ko ēnei ngā painga: he kiato pūngao teitei, he haumaru kaha, he pai te mahi pāmahana teitei, he nui te putanga mana, he roa te huringa, he mama, he penapena utu whakakaha rūma mīhini, he iti te rahi, he roa te ora o te pākahiko, he pai te haumaru, me ētahi atu.
