Meneneirin lithiumbaturi?Gabatarwa ga ƙa'idar aiki da fa'idodin batirin ƙarfe na lithium

Batirin ƙarfe na lithium wani nau'in baturi ne a cikin dangin baturin lithium.Cikakken sunansa shine batirin lithium iron phosphate lithium ion baturi.A cathode abu ne yafi lithium iron phosphate.Saboda aikin sa ya dace da aikace-aikacen wutar lantarki, ana kuma kiransa "batir ƙarfin ƙarfe na lithium".(nan gaba ana kiranta "batir lithium iron")

Ka'idar aiki na baturin ƙarfe na lithium (LiFePO4)
Tsarin ciki na baturi LiFePO4: LiFePO4 tare da tsarin olivine a gefen hagu ana amfani dashi azaman sandar sandar baturi mai kyau, wanda aka haɗa ta foil na aluminum da ingantaccen sandar baturi.A tsakiyar akwai diaphragm na polymer, wanda ke raba ingantacciyar sandar sandar da ba ta da kyau.Koyaya, lithium ion Li + na iya wucewa amma e - ba zai iya ba.A hannun dama akwai madaidaicin sandar baturin da ke tattare da carbon (graphite), wanda aka haɗa shi da foil ɗin tagulla da mummunan sandar baturi.Electrolyte na baturin yana tsakanin saman sama da ƙananan ƙarshen baturin, kuma baturin yana rufe shi da harsashi na ƙarfe.

Lokacin da aka yi cajin baturi LiFePO4, lithium ion Li + a cikin ingantaccen lantarki yana ƙaura zuwa mummunan lantarki ta hanyar membrane na polymer;Yayin aiwatar da fitarwa, lithium ion Li+ a cikin mummunan lantarki yana ƙaura zuwa ingantaccen lantarki ta hanyar diaphragm.Ana kiran baturin lithium-ion bayan ƙaura na ion lithium yayin caji da fitarwa.

Babban aikin baturi LiFePO4
Matsakaicin ƙarfin lantarki na batirin LiFePO4 shine 3.2 V, ƙarfin cajin ƙarewa shine 3.6 V, kuma ƙarfin fitarwar ƙarewa shine 2.0 V. Saboda inganci da tsari daban-daban na kayan lantarki masu inganci da korau da kayan lantarki da masana'antun daban-daban ke amfani da su, aikin su. zai zama ɗan bambanci.Misali, ƙarfin baturi na samfuri ɗaya (misali baturi a cikin fakiti ɗaya) ya bambanta sosai (10% ~ 20%).
