Senotlolo sa bophelo bo bolelele baLFP betri ke motlakase oa eona o sebetsang, o pakeng tsa 3.2 le 3.65 volts, o ka tlaase ho matla a tloaelehileng a sebelisoang ke betri ea NCM.Betri ea lithium iron phosphate e sebelisa phosphate e le thepa e ntle le electrode ea carbon graphite e le electrode e mpe;Ba boetse ba na le bophelo bo bolelele ba ts'ebeletso, botsitso bo botle ba mocheso le ts'ebetso e ntle ea electromechanical.
LFP betrie sebetsa ka matla a motlakase a 3.2V, kahoo ha libeteri tse 'nè li kopantsoe, betri ea 12.8V e ka fumanoa;25.6V betri e ka fumaneha ha libeteri tse 8 li hokahantsoe.Ka hona, k'hemistri ea LFP ke khetho e ntle ka ho fetisisa ea ho khutlisa libeteri tsa lead-acid tse tebileng lits'ebetsong tse fapaneng.Ho fihlela joale, ke matla a bona a tlaase a matla a fokotsang tšebeliso ea bona likoloing tse kholo, hobane li theko e tlaase haholo ebile li sireletsehile.Boemo bona bo ile ba lebisa ho amoheloa ha theknoloji ena 'marakeng oa Chaena, ke ka lebaka leo 95% ea libeteri tsa lithium iron phosphate li etsoang Chaena.
Betri e nang le graphite anode le LFP cathode e sebetsa ka matla a tloaelehileng a 3.2 volts le matla a mangata a 3.65 volts.Ka li-voltage tsena (hape li le tlase haholo), li-cycle tsa bophelo tse 12000 li ka fihlelleha.Leha ho le joalo, libeteri tse nang le graphite anode le NCM (nickel, cobalt le manganese oxide) kapa NCA (nickel, nickel le aluminium oxide) cathode li ka sebetsa ka matla a phahameng, ka matla a holimo a 3.7 volts le matla a mangata a 4.2 volts.Tlas'a maemo ana, ha hoa lebelloa ho fihlella lipotoloho tse fetang 4000 tsa ho tjhaja le ho ntša.
Haeba motlakase o sebetsang o le tlase, electrolyte ea mokelikeli pakeng tsa li-electrode tse peli tsa betri (eo ka eona li-ion tsa lithium li tsamaeang) e tsitsitse haholoanyane ka lik'hemik'hale.Karolo ena e hlalosa hore na ke hobane'ng ha betri ea LTO e sebetsang ho 2.3V le betri ea LFP e sebetsang ho 3.2V e na le bophelo bo molemo ho feta NCM kapa NCA betri e sebetsang ho 3.7V.Ha betri e na le tjhaji e hodimo mme kahoo motlakase o phahame, electrolyte ya metsi e tla qala butle ho senya electrode ya betri.Ka hona, ha ho na betri e sebelisang spinel hajoale.Spinel ke diminerale e entsoeng ka manganese le aluminium.Matla a eona a cathode ke 5V, empa electrolyte e ncha le ho roala elektrode e ntlafalitsoeng lia hlokahala ho thibela kutu.
Ke ka lebaka leo ho hlokahalang ho boloka betri ho SoC e tlaase ka ho fetisisa (boemo ba tefiso kapa% tefiso), hobane e tla sebetsa ka matla a tlaase 'me bophelo ba eona bo tla atolosoa.
