Okwangoku, akukho sisombululo sisebenzayo kwingxaki yokunqanyulwa kwebhetri ye-solid state ngenxa yesigaba sabo sophando nophuhliso esiqhubekayo, esizisa imingeni eyahlukeneyo engasonjululwanga yobugcisa, yezoqoqosho, neyezorhwebo. Ngenxa yemida yobuchwepheshe ekhoyo ngoku, ukuveliswa kobuninzi kusekude kakhulu, kwaye iibhetri ze-solid-state azikafumaneki kwimarike.
Yintoni Ethintela Uphuhliso Lwebhetri Yemeko Eqinileyo?
Iibhetri zesimo esiqinileyosebenzisa i-electrolyte eqinileyo endaweni ye-electrolyte engamanzi efumaneka kwi-electrolyte yendabuko.iibhetri ze-lithium-ionIibhetri ze-lithium ezingamanzi eziqhelekileyo ziqulathe izinto ezine ezibalulekileyo: i-electrode elungileyo, i-electrode engalunganga, i-electrolyte, kunye ne-separator. Ngokwahlukileyo koko, iibhetri ze-solid-state zisebenzisa i-electrolyte eqinileyo endaweni ye-liquid counterpart eqhelekileyo.
Ngenxa yamandla amakhulu obu buchwepheshe bebhetri obuqinileyo, kutheni bungekaziswa kwimarike okwangoku? Kuba utshintsho oluvela kwilabhoratri ukuya kwezorhwebo lujongene nemingeni emibini:ukuba nokwenzeka kobugcisakwayeukuphila ngokwezoqoqosho.
- 1. Ukuba nokwenzeka kobuchwephesha: Isiseko sebhetri ye-solid-state kukutshintsha i-electrolyte engamanzi nge-electrolyte eqinileyo. Nangona kunjalo, ukugcina uzinzo kwindawo yokudibana phakathi kwe-electrolyte eqinileyo kunye nezinto ze-electrode kuzisa umngeni omkhulu. Unxibelelwano olunganelanga lunokubangela ukwanda kokumelana, ngaloo ndlela kunciphisa ukusebenza kwebhetri. Ukongeza, ii-electrolyte eziqinileyo zinengxaki yokuqhuba i-ionic ephantsi kwaye zihamba kancinci.i-lithium ionukuhambahamba, okukhokelela ekutshajeni nasekukhupheni isantya esicothayo.
- Ngaphezu koko, inkqubo yokuvelisa iyinkimbinkimbi ngakumbi. Umzekelo, ii-electrolyte eziqinileyo ze-sulfide kufuneka ziveliswe phantsi kokhuseleko lwegesi engasebenziyo ukuthintela ukusabela kokufuma emoyeni okuvelisa iigesi ezinobuthi. Le nkqubo ibiza kakhulu kwaye inzima kwezobuchwepheshe okwangoku ithintela ukwenzeka kwemveliso enkulu. Ngaphezu koko, iimeko zovavanyo lwelabhoratri zihlala zahlukile kakhulu kwiindawo zokwenyani, nto leyo ebangela ukuba ubuchwepheshe obuninzi bungakwazi ukufikelela kwiziphumo ezilindelekileyo.
- 2. Ukuphila kakuhle kwezoqoqosho:Ixabiso lebhetri eqinileyo liphindwe kaninzi kuneebhetri ze-lithium ezingamanzi zemveli kwaye indlela eya ekuthengisweni izaliswe ziingxaki. Nangona inokhuseleko oluphezulu ngokwethiyori, ekusebenzeni, i-electrolyte eqinileyo inokonakala xa amaqondo obushushu aphezulu, nto leyo ekhokelela ekunciphiseni ukusebenza kwebhetri okanye ukungaphumeleli kwayo.
- Ukongeza, ii-dendrites zinokwenzeka ngexesha lenkqubo yokutshaja nokukhupha i-charger, zigqobhoze i-separator, zibangele ii-short circuits, kwanokuqhuma, nto leyo eyenza ukhuseleko kunye nokuthembeka kube yingxaki ebalulekileyo. Ngaphezu koko, xa inkqubo yokuvelisa encinci inyuswa ukuze ivelise imveliso yemizi-mveliso, iindleko ziya kunyuka kakhulu.
Ziza Kufika Nini Iibhetri Ze-Solid State?
Iibhetri ze-Solid-state kulindeleke ukuba zifumane usetyenziso oluphambili kwii-elektroniki zabathengi abakumgangatho ophezulu, izithuthi zombane ezincinci (ii-EV), kunye namashishini aneemfuno ezingqongqo zokusebenza kunye nokhuseleko, ezifana neenqwelo-moya. Nangona kunjalo, iibhetri ze-solid-state ezikhoyo kwimarike ngoku zisekwinqanaba lokuqala lokuthengisa iingcamango.
Iinkampani zeemoto ezidumileyo kunyeabavelisi bebhetri ye-lithiumIinkampani ezifana neSAIC Motor, iGAC-Toyota, iBMW, iCATL, iBYD, kunye ne-EVE ziphuhlisa iibhetri ze-solid-state ngenkuthalo. Nangona kunjalo, ngokusekelwe kwiishedyuli zabo zamva nje zemveliso, akunakwenzeka ukuba imveliso epheleleyo yeebhetri ze-solid-state iqale ngaphambi kowama-2026-2027 kwangoko. KwaneToyota kuye kwafuneka ihlaziye ixesha layo amaxesha amaninzi kwaye ngoku iceba ukuqala ukuvelisa ngobuninzi ngowama-2030.
Kubalulekile ukuqaphela ukuba ixesha lokufumaneka kweebhetri ezisemgangathweni linokuhluka ngenxa yezizathu ezahlukeneyo ezifana nemingeni yetekhnoloji kunye nokuvunywa kwemithetho.
Izinto Ezibalulekileyo Eziqwalaselweyo Kubathengi
Ngelixa sijonga ngokusondeleyo ukuqhubela phambili kwezoqoqoshoibhetri ye-lithium eqinileyointsimi, kubalulekile ukuba abathengi bahlale bephaphile kwaye bangagungqiswa lulwazi olumangalisayo. Nangona ubuchule bokwenyani kunye nophuhliso lwetekhnoloji kufanelekile ukulindela, zifuna ixesha lokuqinisekiswa. Masithembe ukuba njengoko ubuchwepheshe buqhubela phambili kwaye imakethi ikhula, izisombululo ezintsha zamandla ezikhuselekileyo nezingabizi kakhulu ziya kuvela kwixesha elizayo.
