Ngomhla we-16 kaMeyi, iNkomfa ye-4 yeZithuthi zaMandla amatsha kunye nebhetri yaMandla (CIBF2023 Shenzhen) iNkomfa yoNxibelelwano lwaMazwe ngaMazwe yavulwa ngokumangalisayo kwi-Shenzhen International Convention kunye neZiko lokuBonisa (iHolo entsha).
Kwicandelo lomsitho wokuvula, usihlalo wale nkomfa, i-Academician ye-Chinese Academy of Sciences, u-Ouyang Minggao, wenze intetho ephambili. Uthe ngokubanzi, iibhetri ze-lithium iron phosphate zithathwa njengezikhuselekileyo, kwaye ngokusisiseko, oku kuyinyaniso kwiibhetri ezincinci ze-lithium iron phosphate. Nangona kunjalo, kwiibhetri zamandla amakhulu, ukushisa kwangaphakathi kunokudlula i-800 degrees, edlula iqondo lokushisa lokubola kwezinto ezilungileyo ze-electrode ze-lithium iron phosphate.
Kwiibhetri ezincinci, kuba kukho ukusabela kwekhonkco kunye nokwahlula, izinto eziphathekayo ze-electrode zinokuqala ukubola xa zifikelela ngaphezu kwama-500 degrees, ngoko ke iibhetri ezincinci azikho kuloluhlu. Kodwa iibhetri ezinkulu zeyure ye-ampere zinokufikelela kuma-700-900 degrees, ezinokutyhoboza kwaye ziwele esi sahlulelo, kubangele ukubola kwezinto ezilungileyo ze-electrode. Ngoku iibhetri zokugcina amandla ngokusisiseko zingaphezulu kweeyure ezingama-300 zeampere, nto leyo iseyingozi kakhulu.
Ukujonga kwakhona kwimveliso yegesi ye-lithium iron phosphate, i-hydrogen eveliswayo iya kwanda ngokuthe ngcembe, kwaye ngokunyuka kwe-SOC, i-hydrogen.umxholoingaphezulu kwama-50%, nto leyo eyingozi kakhulu. Ukongezelela, xa kuthelekiswa nemingcipheko evuthayo kunye neziqhushumbisi zeentlobo ezimbini zeebhetri, isalathisi esinokutsha kunye nokuqhuma kweebhetri ze-lithium iron phosphate ziphindwe kabini kwiibhetri ze-ternary. Iibhetri ze-ternary ziqhelekile ekubalekeni kwe-thermal kwaye zikhanyise ngokwazo. Iibhetri zeLithium iron phosphate azikwazi kuzikhanyisela ngokwazo, kodwa umngcipheko wogqabhuko-dubulo lwerhasi uphezulu kunolo lweebhetri ze-ternary. Nje ukuba idibane neentlantsi ngaphandle, iba yingozi ngakumbi.
Intsha yethu entsha600W, 1200W, kunye 2000W amandla aphathwayo sunikezelosngoku zodwa kwimarike kwaye zizo kuphela ezisebenzisa i-manganese lithium iiseli zesingxobo esincinci. Isizathu sokwenza olu khetho lusekelwe ngokuchanekileyo ekufuneni ukhuseleko lokugqibela. Ngokukhetha i-manganese lithium, le nto ikhethekileyo yokwenza iiseli ezincinci zepakethe, inokunciphisa imingcipheko enokubakho yokhuseleko kwaye iqinisekise ukuba inokubonelela abasebenzisi ngeziqinisekiso ezithembekileyo zokhuseleko kwiimeko ezahlukeneyo zokusetyenziswa, ukuphepha iimeko ezinobungozi ezifana nokuqhuma kwegesi okunokuthi kwenzeke kwiindawo ezinkulu. ibhetri ye-lithium yentsimbi ye-phosphate eyodwa kunye nomthamo omkhulu, kunye neengozi ezifihliweyo eziziswa yi-self-thermal runaway yeebhetri ze-ternary, ngaloo ndlela idala amava omsebenzisi anoxolo kunye nexhala kubasebenzisi.
