Ibhethri ye-lithium iron phosphate kanye nebhethri ye-lithium iron phosphate energy density
Ibhethri ye-lithium iron phosphate, eyaziwa nangokuthi ibhethri ye-LFP, iwuhlobo lwebhethri ye-lithium-ion ephinde ishajwe eselikhula ngokuduma ezinhlelweni ezihlukene zezinhlelo zokusebenza, okuhlanganisa izimoto zikagesi, ukugcinwa kwamandla avuselelekayo, nezinto zikagesi eziphathwayo. Kulesi sihloko, sizohlola izinzuzo nezinselelo zebhethri le-LFP, ngokugxila ngokukhethekile ekumineni kwamandla.
Enye yezinzuzo eziyinhloko zebhethri ye-LFP ukuminyana kwayo okuphezulu kwamandla. Ukuminyana kwamandla isilinganiso senani lamandla elingagcinwa kuvolumu ethile noma isisindo sebhethri. Ibhethri le-LFP linomthamo omkhulu wamandla uma liqhathaniswa nezinye izinhlobo zamabhethri angashajwa, njengamabhethri e-lead-acid namabhethri e-nickel-metal hydride. Lokhu kusho ukuthi ibhethri ye-LFP ingagcina amandla engeziwe ngeyunithi ngayinye yesisindo noma ivolumu, okubaluleke kakhulu ezinhlelweni zokusebenza lapho isisindo nesikhala kunqunyelwe.
Kodwa-ke, ukuminyana kwamandla ebhethri ye-LFP kusengaphansi kunamanye amabhethri e-lithium-ion, njengebhethri ye-lithium cobalt oxide nebhethri ye-lithium nickel cobalt aluminium oxide. Lokhu kungenxa ye-voltage ephansi yebhethri ye-LFP, engaba ngu-3.2 volts ngeseli ngayinye uma kuqhathaniswa nama-volts angu-3.7 ngeseli ngayinye yebhethri ye-lithium cobalt oxide. I-voltage ephansi yebhethri ye-LFP isho ukuthi amaseli amaningi ayadingeka ukuze kuzuzwe i-voltage efanayo namanye amabhethri e-lithium-ion, angandisa usayizi nesisindo sebhethri.
Naphezu kokuminyana kwamandla aphansi, ibhethri ye-LFP inezinzuzo ezimbalwa ngaphezu kwezinye izinhlobo zamabhethri e-lithium-ion. Enye yezinzuzo eziyinhloko ukuphepha kwayo. Ibhethri le-LFP lizinze kakhulu futhi alijwayele ukubaleka ngokushisayo, okuwukukhathazeka ngokuphepha kwezinye izinhlobo zamabhethri e-lithium-ion. Ukwengeza, ibhethri ye-LFP inokuphila komjikelezo omude futhi ingakwazi ukumelana nenani eliphakeme lokukhokhiswa nokukhishwa kwemijikelezo uma kuqhathaniswa nezinye izinhlobo zamabhethri e-lithium-ion, okwenza kube inketho ethembekile futhi engabizi ngokuhamba kwesikhathi.
Sengiphetha, ibhethri ye-LFP iwubuchwepheshe obuthembisayo obunamandla amakhulu kanye nezinzuzo ezimbalwa ngaphezu kwezinye izinhlobo zamabhethri e-lithium-ion, njengokuphepha nempilo yomjikelezo omude. Nakuba ukuminyana kwamandla ebhethri ye-LFP kusengaphansi kunamanye amabhethri e-lithium-ion, ucwaningo oluqhubekayo nokuthuthukiswa kuhloswe ngayo ukukhulisa amandla ayo ngenkathi kugcinwa ukuphepha nokuthembeka kwayo. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, kulindeleke ukuthi ibhethri le-LFP libambe iqhaza elibaluleke kakhulu ekushintsheni okubheke kwikusasa lamandla elizinzile nelivuselelekayo.
