Ukhiye wempilo ende yeIbhethri ye-LFP amandla kagesi ayo okusebenza, aphakathi kuka-3.2 no-3.65 volts, aphansi kunevoltheji evame ukusetshenziswa ibhethri le-NCM.Ibhethri ye-lithium iron phosphate isebenzisa i-phosphate njengento enhle kanye ne-carbon graphite electrode njenge-electrode engalungile;Futhi banempilo ende yesevisi, ukuzinza okuhle kokushisa nokusebenza okuhle kwe-electromechanical.
Ibhethri ye-LFPisebenza nge-voltage yegama engu-3.2V, ngakho-ke uma amabhethri amane exhunyiwe, ibhethri engu-12.8V ingatholakala;Ibhethri elingu-25.6V lingatholwa uma amabhethri angu-8 axhunyiwe.Ngakho-ke, ikhemistri ye-LFP iyisinqumo esingcono kakhulu sokushintsha amabhethri e-lead-asidi yomjikelezo ojulile ezinhlelweni ezihlukahlukene.Kuze kube manje, amandla abo aphansi anciphisa ukusetshenziswa kwazo ezimotweni ezinkulu, ngoba zishibhile futhi ziphephile.Lesi simo siholele ekwamukelweni kwalobu buchwepheshe emakethe yaseShayina, yingakho i-95% yamabhethri e-lithium iron phosphate enziwa eChina.
Ibhethri ene-graphite anode kanye ne-LFP cathode isebenza ku-voltage yegama elingu-3.2 volts kanye ne-voltage enkulu engu-3.65 volts.Ngala ma-voltage (futhi aphansi kakhulu), imijikelezo yempilo eyi-12000 ingafinyelelwa.Kodwa-ke, amabhethri ane-graphite anode ne-NCM (nickel, cobalt kanye ne-manganese oxide) noma i-NCA (nickel, nickel ne-aluminium oxide) i-cathode ingasebenza ku-voltage ephakeme, ne-voltage yegama engu-3.7 volts kanye ne-voltage ephezulu engu-4.2 volts.Ngaphansi kwalezi zimo, akulindelekile ukufeza imijikelezo yokushaja nokukhipha engaphezu kuka-4000.
Uma i-voltage yokusebenza iphansi, i-electrolyte ewuketshezi phakathi kwama-electrode amabhethri amabili (okuhamba ngawo ama-ion e-lithium) izinzile ngokwekhemikhali.Le ngxenye ichaza ukuthi kungani ibhethri ye-LTO esebenza ku-2.3V kanye nebhethri ye-LFP esebenza ku-3.2V inokuphila okungcono kunebhethri ye-NCM noma ye-NCA esebenza ku-3.7V.Uma ibhethri inokushajwa okuphezulu futhi ngenxa yalokho i-voltage ephezulu, i-electrolyte ewuketshezi izoqala kancane ukumosha i-electrode yebhethri.Ngakho-ke, alikho ibhethri elisebenzisa i-spinel okwamanje.I-spinel iyiminerali eyakhiwe yi-manganese ne-aluminium.I-cathode voltage yayo ingu-5V, kodwa i-electrolyte entsha kanye ne-electrode coating ethuthukisiwe kuyadingeka ukuze kuvinjelwe ukugqwala.
Yingakho kudingekile ukugcina ibhethri ku-SoC ephansi kakhulu (isimo sokushaja noma i-%), ngoba izosebenza ku-voltage ephansi futhi impilo yayo izonwetshwa.
