Meneneƙarfe na lithiumBatir? Gabatarwa ga ƙa'idar aiki da fa'idodin batirin ƙarfe na lithium

Batirin ƙarfe na Lithium wani nau'in baturi ne a cikin dangin batirin lithium. Cikakken sunansa shine batirin lithium iron phosphate lithium ion. Kayan cathode galibi shine lithium iron phosphate. Saboda aikin sa ya dace musamman don amfani da wutar lantarki, ana kuma kiransa "batir ɗin ƙarfin ƙarfe na lithium". (wanda daga baya ake kira "batir ɗin ƙarfe na lithium")

Ka'idar aiki na batirin ƙarfe na lithium (LiFePO4)
Tsarin ciki na batirin LiFePO4: Ana amfani da LiFePO4 mai tsarin olivine a hagu a matsayin sandar tabbatacce na batirin, wanda aka haɗa ta da foil ɗin aluminum da sandar tabbatacce na baturin. A tsakiya akwai diaphragm ɗin polymer, wanda ke raba sandar tabbatacce daga sandar korau. Duk da haka, lithium ion Li+ na iya wucewa amma e-e-ba zai iya wucewa ba. A gefen dama akwai sandar korau na batirin da aka haɗa da carbon (graphite), wanda aka haɗa ta da foil ɗin jan ƙarfe da sandar korau na baturin. Elektrolyt ɗin baturin yana tsakanin ƙarshen sama da na ƙasa na baturin, kuma an rufe batirin da harsashi na ƙarfe.

Lokacin da aka yi caji da batirin LiFePO4, lithium ion Li+ da ke cikin electrode mai kyau yana ƙaura zuwa electrode mara kyau ta cikin membrane na polymer; A lokacin fitar da bayanai, lithium ion Li+ da ke cikin electrode mara kyau yana ƙaura zuwa electrode mai kyau ta cikin diaphragm. An sanya wa batirin lithium-ion suna ne bayan ƙaura da lithium ions yayin caji da fitarwa.

Babban aikin batirin LiFePO4
Ƙarfin wutar lantarki na batirin LiFePO4 shine 3.2 V, ƙarfin caji na ƙarshe shine 3.6 V, kuma ƙarfin fitarwa na ƙarshe shine 2.0 V. Saboda bambancin inganci da tsari na kayan lantarki masu kyau da marasa kyau da kayan lantarki da masana'antun daban-daban ke amfani da su, aikinsu zai ɗan bambanta. Misali, ƙarfin batirin samfurin iri ɗaya (batir na yau da kullun a cikin fakiti ɗaya) ya bambanta sosai (10% ~ 20%).
