Batirin lithium iron phosphate shima batirin lithium ne, a zahiri reshe ne na batirin lithium ion, yana ɗauke da lithium manganese oxide, lithium cobalt oxide da ternary lithium baturi. Ayyukansa sun fi dacewa da aikace-aikacen wutar lantarki. Hakanan ana kiranta lithium iron phosphate power baturi, wanda kuma ake kira batirin baƙin ƙarfe na lithium. Don haka, fa’idar batir phosphate na lithium baƙin ƙarfe galibi yana nufin amincin su da kwanciyar hankali idan aka kwatanta da sauran batura a aikace-aikacen wuta. A wasu fannoni, zai sami fa’ida akan baturan lithium na ternary da batir-acid.

Da farko, batirin lithium baƙin ƙarfe phosphate suna da mafi girman aikin zafin jiki kuma suna iya jure yanayin zafi daga 350 ° C zuwa 500 ° C, yayin da lithium manganate/cobalt oxide yawanci kusan 200 ° C ne. Abubuwan ingantaccen batirin lithium na ternary shima zai kasance a 200 ° C.

Abu na biyu, batirin lithium iron phosphate suna da tsawon rayuwa fiye da batir-acid da batirin lithium na ƙasa. “Rayuwar zagayowar” batirin gubar-acid shine kusan sau 300, kuma matsakaicin shine sau 500; yayin da rayuwar ka’idar batirin lithium ternary zai iya kaiwa sau 2000, amma idan aka yi amfani da shi kusan sau 1000, ƙarfin zai ragu zuwa 60%. Kuma ainihin rayuwar batirin lithium iron phosphate lithium ya kai sau 2000. A wannan lokacin, akwai har yanzu 95% na iya aiki, da ka’idar sake zagayowar rayuwa iya isa fiye da 3000 sau.

Na uku, akwai fa’idodi da yawa idan aka kwatanta da baturan gubar-acid:

1. Babban iyawa. Ana iya yin tantanin halitta 3.2V zuwa 5Ah ~ 1000 Ah (1 Ah = 1000m Ah), kuma tantanin 2V na batirin gubar-acid yawanci 100Ah ~ 150 Ah.

2. Hasken nauyi. Adadin baturin phosphate na lithium baƙin ƙarfe na ƙarfin iri ɗaya shine 2/3 na ƙarar baturin gubar-acid, kuma nauyin shine 1/3 na ƙarshen.

3. Saurin yin caji. Farawa na baturin phosphate na lithium baƙin ƙarfe zai iya kaiwa 2C, wanda zai iya gane caji mai girma; Bukatar baturin gubar-acid na yanzu yana yawanci tsakanin 0.1C da 0.2C, kuma ba za a iya samun saurin caji ba.

4. Kariyar muhalli. Batir gubar-acid yana ɗauke da ƙarfe mai yawa, wanda zai samar da ruwa mai datti. Lithium iron phosphate baturi ba ya ƙunshi wani nauyi karafa, kuma babu wani gurɓata a samar da amfani.

5. High kudin yi. Duk da cewa batirin gubar-acid ya fi arha fiye da kayan, farashin sayan ya yi ƙasa da batirin lithium baƙin ƙarfe phosphate, amma dangane da rayuwar sabis da kiyayewa na yau da kullun, ba su da tattalin arziki kamar batirin ƙarfe phosphate na lithium. Sakamakon aikace-aikacen aikace-aikacen ya nuna cewa ƙimar aikin batir phosphate na lithium baƙin ƙarfe ya ninka fiye da sau 4 na batirin gubar-acid.

Kodayake kewayon aikace -aikacen batirin lithium baƙin ƙarfe phosphate galibi ana nuna shi a cikin ikon wutar lantarki, a ka’idar ana iya ƙara shi zuwa ƙarin filayen, yana yiwuwa a haɓaka ƙimar fitarwa da sauran fannoni, kuma shigar da filayen aikace -aikacen gargajiya na sauran nau’ikan. lithium-ion batura.
