Eminyakeni yakamuva,amabhethri e-lithium-ionseziphenduke imithombo yamandla ebalulekile ezinhlobonhlobo zezinto zikagesi. Kodwa-ke, ukukhathazeka ngokuphepha okuzungeze lawa mabhethri kuqubule ingxoxo ngezingozi zawo ezingaba khona. I-Lithium Iron Phosphate (LiFePO4) iyikhemikhali yebhethri ethile ethole ukunakwa ngenxa yokuphepha kwayo okuthuthukisiwe uma kuqhathaniswa namabhethri e-Li-ion endabuko. Ngokuphambene neminye imibono eyiphutha, amabhethri e-lithium iron phosphate awabangeli ukuqhuma noma usongo lomlilo. Kulesi sihloko, sihlose ukukhipha lolu lwazi olungalungile futhi sicacise izici zokuphepha zamabhethri e-LiFePO4.
Funda ngamabhethri e-lithium iron phosphate
Ibhethri ye-LiFePO4 ibhethri ye-lithium-ion ethuthukisiwe esebenzisa i-lithium iron phosphate njenge-cathode material. Le khemistri inikezela ngezinzuzo ezibalulekile, okuhlanganisa ukuminyana kwamandla aphezulu, impilo yomjikelezo omude, izinga eliphansi lokuzikhulula, futhi okubaluleke kakhulu, ukuphepha okuthuthukisiwe. Ngokuklama, amabhethri e-lithium iron phosphate azinzile ngokwemvelo futhi anengozi ephansi yokubaleka okushisayo—into engaholela ekuqhumeni nemililo.
Isayensi ngemuva kokuphepha kwebhethri ye-LiFePO4
Esinye sezizathu eziyinhloko ukuthi amabhethri e-LiFePO4 abhekwa njengephephile ukwakheka kwawo okuqinile kwekristalu. Ngokungafani namanye amabhethri e-lithium-ion izinto zawo ze-cathode ezihlanganisa i-lithium cobalt oxide noma i-lithium nickel manganese cobalt (NMC), i-LiFePO4 inohlaka oluzinzile. Lesi sakhiwo sekristalu sivumela ukuchithwa okungcono kokushisa ngesikhathi sokusebenza kwebhethri, ukunciphisa ubungozi bokushisa ngokweqile kanye nomphumela wokubaleka okushisayo.
Ngaphezu kwalokho, ikhemikhali yebhethri ye-LiFePO4 inezinga lokushisa eliphakeme lokubola okushisayo uma liqhathaniswa namanye amakhemikhali e-Li-ion. Lokhu kusho ukuthi amabhethri e-LiFePO4 angakwazi ukumelana namazinga okushisa aphezulu ngaphandle kokuwohloka kokushisa, okwandisa umkhawulo wokuphepha ezinhlelweni ezihlukahlukene.
Izinyathelo zokuphepha ekwakhiweni kwebhethri le-LiFePO4
Izinyathelo ezihlukahlukene zokuphepha zisetshenziswa ohlelweni lokukhiqiza amabhethri e-LiFePO4 ukuze kuncishiswe ingozi yokuqhuma nomlilo. Lezi zinyathelo zisiza ukuthuthukisa ukuphepha okuphelele nokuthembeka kwamabhethri e-LiFePO4. Ezinye izici zokuphepha eziphawulekayo zifaka:
1. Ama-electrolyte azinzile: Amabhethri e-LiFePO4 asebenzisa ama-electrolyte angashi, ngokungafani namabhethri e-lithium-ion endabuko asebenzisa i-electrolyte ephilayo evuthayo. Lokhu kuqeda amathuba okushiswa kwe-electrolyte, okunciphisa kakhulu ingozi yomlilo.
2. Isistimu yokuphatha ibhethri (BMS): Iphakethe lebhethri le-LiFePO4 ngalinye liqukethe i-BMS, enemisebenzi efana nokuvikela ukushajwa ngokweqile, ukuvikela ukuchitheka ngokweqile, nokuvikelwa kwesekethe emfishane. I-BMS ihlale iqapha futhi ilawula amandla kagesi ebhethri, amanje, kanye nezinga lokushisa ukuze kuqinisekiswe ukusebenza kwebhethri okuphephile nokufanele.
3. Ukuvimbela ukubaleka kwe-thermal: Amabhethri e-LiFePO4 athambekele kancane ekubalekeni okushisayo ngenxa yekhemikhali yawo ephephile ngokwemvelo. Esimeni sesehlakalo esibi kakhulu, ifekthri yebhethri ye-lifepo4 ivamise ukwengeza izindlela zokuvikela ukushisa okushisayo, njengamafusi ashisayo noma izindlu ezikwazi ukumelana nokushisa, ukuze kuqhutshekwe nokunciphisa ubungozi.
Izicelo kanye nezinzuzo zebhethri ye-LiFePO4
Amabhethri e-LiFePO4 asetshenziswa ezimbonini eziningi ezihlukahlukene, kuhlanganise nezimoto zikagesi (EVs), ukugcinwa kwamandla avuselelekayo, ama-electronics abathengi, ngisho nemishini yezokwelapha. Ukuphepha kwazo okuthuthukisiwe, ukuphila isikhathi eside, nokwethembeka kuzenza zilungele izinhlelo zokusebenza ezinzima kangaka.
Ekuphetheni
Ngokuphambene nemibono eyiphutha, amabhethri e-LiFePO4 awanayo ingozi yokuqhuma noma yomlilo. Isakhiwo sayo sekristalu esizinzile, izinga lokushisa eliphezulu lokubola okushisayo, nezinyathelo zokuphepha ezifakwe enqubweni yokukhiqiza kuyenza iphephe ngokwemvelo. Ngesidingo esikhulayo sezixazululo zokugcina amandla ezithuthukisiwe, amabhethri e-lithium iron phosphate abekwe njengenketho ethembekile nephephile ezimbonini ezahlukahlukene. Ulwazi olungelona iqiniso mayelana nokuphepha kwebhethri kufanele kubhekwane nalo futhi kuthuthukiswe ulwazi olunembile ukuze kuqinisekiswe ukuthi abantu benza izinqumo ezinolwazi mayelana nokukhetha kwamandla.
Uma uthanda amabhethri e-lithium iron phosphate, wamukelekile ukuthintana ne-lifepo4 battery factory Radiance toFunda kabanzi.
