Ko te Whakatakinga o te Anode me nga mea Cathode o te pākahiko Lithium Ion

Mo te pākahiko lithium me te pākahiko katote lithium (no te pākahiko lithium polymer ano hoki no te pākahiko lithium katote), he pākahiko lithium e whakamahi ana i te whakarewa lithium, te koranu lithium ranei hei rauemi cathode. Ko te ahuatanga matū o te whakarewa lithium he tino kaha, na te mea e hiahiatia ana e te whakarewa lithium nga whakaritenga tino nui mo te taiao mo tana tukanga, te rokiroki me te tono. Ko te rauemi cathode o te pākahiko katote lithium he mea hangahanga intercalated penei i te waro. He haumaru ake te pākahiko katote Lithium na te mea ko te Li katote noa e tuku ana i waenga anode me te cathode i roto i te pākahiko. Mo te pākahiko lithium katote me te pākahiko polymer lithium, Ko te electrolyte o te pākahiko lithium katote he ahua wai, ko tera o te pākahiko lithium polymer he gel, he ahua totoka ranei, e pai ake ai te pai o te pākahiko.

Tuatahi

Ko te ingoa putaiao o te pākahiko katote lithium he pākahiko tuarua lithium, he rite nga rauemi cathode. He rereke mai i te pākahiko lithium tuatahi mo te lithium hei hiko kotahi, ko te pākahiko tuarua lithium he electrolyte wai e hono ana i te LiPF6 me te LiClO4 ki te electrolyte o DMC:EC(v:v=1:1). Ko etahi electrolyte he whakarereketanga, engari ko te pākahiko tuarua lithium he pākahiko wai tonu.

Mo nga mea o roto o te pākahiko lithium polymer, he polymer tona electrolyte, ko te tikanga he electrolyte me te electrolyte totoka. Kua hangaia e Korea ki te Tonga te pākahiko gel me te PEO-ion hei electrolyte. Kaore i te mohiotia mena he penei te momo pākahiko kei GalaxyRound, LGGFlex ranei.

Tuarua

He rereke etahi o te kete i waenga i te pākahiko lithium polymer me te pākahiko lithium. Ko te pākahiko Lithium he kete anga rino (18650, 2320 ranei), ko te pākahiko lithium polymer kua taia e te kiriata konumohe takai kirihou, i whakaingoatia te pukoro pukoro.

Ko etahi o te pākahiko lithium he electrolyte totoka katoa, penei i te LiPON, NASICON, perovskite, LiSICON, te electrolyte ceramic me te kawe teitei, te electrolyte karaihe ranei i hangaia e te taonga amorphous. No te pākahiko tuarua lithium pea.

I roto i te katoa, ka taea te wehewehe i te pākahiko lithium ki nga waahanga e rua: te pākahiko whakarewa lithium me te pākahiko lithium katote. Ko te tikanga, karekau e taea te whakakii i te pākahiko konganuku lithium me te lithium whakarewa, engari karekau te pākahiko lithium katote i roto i te lithium whakarewa engari ka taea te utu. Ko te pākahiko Lithium, te pākahiko katote lithium me te pākahiko polymer lithium he rerekee nga whakaaro.
