Intshayelelo:
Iibhetri zeLithium ziye zaba yinxalenye ebalulekileyo yobomi bethu bemihla ngemihla, ukunika amandla yonke into ukusuka kwii-smartphones kunye neelaptops ukuya kwizithuthi zombane kunye neenkqubo zokugcina amandla. Phakathi kweentlobo ezahlukeneyo zeebhetri ze-lithium kwimarike, iinketho ezimbini ezidumileyo ziyi-lithium iron phosphate (LiFePO4) iibhetri kunye neebhetri ze-ternary lithium. Ukuqonda umahluko phakathi kwezi ntlobo zimbini zeebhetri ze-lithium kubalulekile ukwenza izigqibo ezinolwazi xa ukhetha umthombo wamandla ofanelekileyo kwisicelo esithile.
Lithium iron phosphate ibhetri (LiFePO4)
Ibhetri ye-lithium ye-iron phosphate, eyaziwa ngokuba yi-LFP ibhetri, ibhetri ye-lithium-ion etshajwayo kusetyenziswa i-lithium iron phosphate njenge-cathode material. Ezi bhetri zaziwa ngokuxinana kwamandla aphezulu, ubomi bomjikelo omde, kunye nozinzo oluhle kakhulu lwe-thermal kunye neekhemikhali. Enye yezona zinto ziluncedo kwiibhetri ze-LiFePO4 lukhuseleko lwazo lwendalo, njengoko zingenako ukumelana ne-thermal runaway kwaye zixhathisa ngakumbi ukutshaja kunye nokujikeleza okufutshane kunezinye iintlobo zeebhetri ze-lithium.
Ternary lithium ibhetri
I-ternary lithium ibhetri, ngakolunye uhlangothi, ibhetri ye-lithium-ion esebenzisa inhlanganisela ye-nickel, i-cobalt, kunye ne-manganese kwizinto ze-cathode. Le ndibaniselwano yentsimbi yenza ukuba iibhetri ze-lithium ze-ternary ukuba zifezekise ukuxinana kwamandla aphezulu kunye nokuphuma kwamandla xa kuthelekiswa neebhetri ze-lithium iron phosphate. Iibhetri ze-Ternary ze-lithium ziqhele ukusetyenziswa kwizithuthi zombane kunye nokusetyenziswa kwamandla aphezulu, apho ubuninzi bamandla kunye nokutshaja ngokukhawuleza kubaluleke kakhulu.
Umahluko ophambili:
1. Ukuxinana kwamandla:Omnye umahluko ophambili phakathi kwe-lithium iron phosphate kunye neebhetri ze-ternary lithium kukuxinana kwamandla abo. Iibhetri ze-Ternary ze-lithium ngokubanzi zinoxinano lwamandla aphezulu, okuthetha ukuba zinokugcina amandla amaninzi kumthamo ofanayo okanye ubunzima kuneebhetri ze-lithium iron phosphate. Oku kwenza ukuba iibhetri ze-ternary ze-lithium zilungele izicelo ezifuna amandla aphezulu okugcina amandla, njengezithuthi zombane kunye nezixhobo zombane eziphathwayo.
2. Ubomi bomjikelo:Iibhetri ze-lithium iron phosphate ziyaziwa ngobomi bazo bomjikelo omde kwaye ziyakwazi ukumelana nenani elikhulu leentlawulo kunye nokukhupha imijikelo ngaphandle kokuthotywa okubonakalayo kokusebenza. Ngokwahlukileyo, nangona iibhetri ze-lithium ze-ternary zibonelela ngamandla aphezulu oxinaniso, ubomi babo bomjikelezo bunokuba bufutshane xa kuthelekiswa neebhetri ze-lithium iron phosphate. Umahluko kubomi bomjikelezo kukuqwalaselwa okubalulekileyo xa ukhetha ibhetri yokusetyenziswa kwexesha elide kunye nokuqina.
3. Ukhuseleko: Kwiibhetri ze-lithium, ukhuseleko luyinto ephambili. Iibhetri ze-lithium ze-iron phosphate zithathwa njengekhuselekile kuneebhetri ze-lithium ze-ternary ngenxa yokuzinza kwazo kunye nokuchasana nokubaleka kwe-thermal. Oku kwenza ukuba iibhetri ze-LiFePO4 zibe yinto yokuqala yokukhetha ukhuseleko-usetyenziso lokuqala olufana neenkqubo zokugcina amandla kunye nokugcinwa kwamandla amileyo.
4. Iindleko: Xa kuthelekiswa neebhetri ze-lithium iron phosphate, iindleko zokwenziwa kweebhetri ze-ternary lithium zihlala ziphezulu. Iindleko eziphezulu zibangelwa ukusetyenziswa kwe-nickel, i-cobalt kunye ne-manganese kwizinto ze-cathode, kunye neenkqubo zokuvelisa eziyinkimbinkimbi ezifunekayo ukufezekisa ubuninzi bamandla kunye nokuphuma kwamandla. Ngokwahlukileyo, iibhetri ze-lithium iron phosphate ziyaziwa ngeendleko-zokusebenza, okwenza kube yinto ethandwayo yokukhetha izicelo apho iindleko zidlala indima ebalulekileyo kwinkqubo yokwenza izigqibo.
Khetha ibhetri elungileyo kwiimfuno zakho
Xa ukhetha iibhetri ze-lithium iron phosphate kunye neebhetri ze-lithium ze-ternary, iimfuno ezithile zesicelo esijoliswe kuyo kufuneka ziqwalaselwe. Kwizicelo apho ukhuseleko, ubomi bomjikelezo omude kunye neendleko-zokusebenza ziphambili, iibhetri ze-lithium iron phosphate zinokuba yinto yokuqala yokukhetha. Kwelinye icala, usetyenziso olufuna uxinano lwamandla aphezulu, ukutshaja okukhawulezileyo, kunye nokuphuma kwamandla aphezulu, iibhetri ze-lithium ze-ternary zinokuba lukhetho olufanelekileyo.
Ukushwankathela, zombini iibhetri ze-lithium iron phosphate kunye neebhetri ze-lithium ze-ternary zineenzuzo ezizodwa kwaye zenzelwe ukuhlangabezana neemfuno ezahlukeneyo zokusebenza.
