Njengoko sisiya kwikamva elicocekileyo, eliluhlaza, imfuno yezisombululo ezisebenzayo, ezizinzileyo zokugcina amandla zikhula ngokukhawuleza.Enye yetekhnoloji ethembisayo ziibhetri ze-lithium-ion, ezifumana ukuthandwa ngenxa yoxinano lwamandla aphezulu kunye nobomi obude xa kuthelekiswa neebhetri ze-asidi ezikhokelayo.Ngaphakathi kweibhetri ye-lithium-ionusapho, iintlobo ezimbini eziphambili ezidla ngokuthelekiswa iibhetri ze-lithium iron phosphate (LiFePO4) kunye neebhetri ze-lithium ternary.Ngoko ke, makhe simbe nzulu: yeyiphi engcono?
Malunga neebhetri ze-lithium iron phosphate
Iibhetri ze-Lithium iron phosphate (LiFePO4) ziyaziwa ngokuzinza, ukhuseleko kunye nobomi bomjikelezo omude.Ibhetri ehlaziywayo esebenzisa i-lithium ions ukugcina kunye nokukhulula amandla ngexesha lokuhlawula kunye nokukhupha imijikelezo.Xa kuthelekiswa neebhetri ze-lithium ze-ternary, iibhetri ze-lithium iron phosphate zinobuninzi bamandla obuphantsi, kodwa ukuzinza kwazo kunye nexesha lokuphila zenza oku kusilela.Ezi bhetri zinozinzo oluphezulu lwe-thermal, okwenza ukuba luxhathise ukushisa kunye nokunciphisa umngcipheko wokubaleka kwe-thermal, inkxalabo ebalulekileyo kwizicelo ezininzi.Ukongezelela, iibhetri ze-LiFePO4 ngokuqhelekileyo ziyakwazi ukumelana nemijikelo ephezulu kakhulu yokuhlawulela kunye nokukhupha, ukuya kuthi ga kwimijikelezo ye-2000 okanye ngaphezulu, ezenza zilungele ixesha elide, izicelo eziphezulu zokusebenza ezifana neenqwelo zombane (EVs).
Malunga neebhetri ze-ternary lithium
Ngakolunye uhlangothi, iibhetri ze-lithium ze-ternary, ezikwabizwa ngokuba yi-lithium nickel-cobalt-aluminum oxide (NCA) okanye i-lithium nickel-manganese-cobalt oxide (NMC) iibhetri, zinika ubuninzi bamandla obuphezulu kuneebhetri ze-LiFePO4.Uxinaniso lwamandla oluphezulu luvumela umthamo omkhulu wogcino kunye nexesha elide lokusebenza kwesixhobo.Ukongeza, iibhetri ze-ternary ze-lithium zihlala zibonelela ngemveliso yamandla ephezulu, izenza zilungele usetyenziso olufuna ugqabhuko lwamandla olukhawulezayo, njengezixhobo zamandla okanye i-elektroniki yabathengi.Nangona kunjalo, njengoko uxinaniso lwamandla lusanda, kukho urhwebo oluthile.Iibhetri ze-Ternary ze-lithium zinokuba nobomi obufutshane benkonzo kwaye zijongene neengxaki ze-thermal kunye nokungazinzi kuneebhetri ze-LiFePO4.
Ukumisela ukuba yeyiphi ibhetri engcono ekugqibeleni kuxhomekeke kwiimfuno zesicelo esithile.Apho ukhuseleko kunye nokuphila ixesha elide zizinto eziphambili eziphambili, ezifana neenqwelo zombane okanye iinkqubo zamandla avuselelekayo, iibhetri ze-lithium iron phosphate zikhetho lokuqala.Ukuzinza, ubomi bomjikelezo omude, kunye nokuchasana nokubaleka kwe-thermal ye-LiFePO4 iibhetri kubenza kube lukhetho oluhle kakhulu kwizicelo ezibalulekileyo apho ukhuseleko lubaluleke kakhulu.Ngaphaya koko, kwizicelo ezifuna ukukhutshwa kwamandla aqhubekayo okanye apho ubunzima kunye nendawo zizinto ezibalulekileyo, iibhetri ze-lithium ze-ternary zinokuba lukhetho olufanelekileyo ngakumbi ngenxa yobuninzi bamandla abo.
Zombini ezi ntlobo zeebhetri zineengenelo kunye nezingeloncedo zazo, kwaye iimfuno ezithile zesicelo kufuneka ziqwalaselwe ngononophelo phambi kokwenza isigqibo.Izinto ezifana nokhuseleko, ubomi bonke, ukuxinana kwamandla, ukuphuma kwamandla, kunye neendleko zonke kufuneka ziqwalaselwe.
Ukushwankathela, akukho mntu uphumeleleyo kwingxoxo-mpikiswano phakathi kweebhetri ze-lithium iron phosphate kunye neebhetri ze-ternary lithium.Indlela nganye ineenzuzo zayo kunye nokungonakali, kwaye ukhetho luxhomekeke kwiimfuno zesicelo esithile.Njengoko iteknoloji iqhubeka nokuphuhlisa, zombini iintlobo zeebhetri ze-Li-ion ngokungathandabuzekiyo ziya kuphucula ngokusebenza, ukhuseleko kunye nokusebenza kakuhle.Kungakhathaliseki ukuba yeyiphi ibhetri ogqiba ukuyikhetha, kubalulekile ukuqhubeka ukwamkela kunye nokutyala imali kwizisombululo zokugcina amandla ezizinzileyo kunye nokusingqongileyo ezinegalelo kwikamva eliluhlaza kubo bonke.
Ukuba unomdla kwiibhetri ze-lithium, wamkelekile ukuba uqhagamshelane nenkampani yebhetri ye-lithium Radiance ukuyaFunda ngokugqithisileyo.
