Kwiminyaka yakutshanje, iibhetri ze-lithium-ion ziye zavela njengeteknoloji ebalulekileyo ekutshintsheni kwimithombo yamandla avuselelekayo kunye nezithuthi zombane (EVs). Imfuno ehlala isanda yeebhetri ezisebenza ngokufanelekileyo kwaye ezifikelelekayo zikhuthaze uphuhliso olubalulekileyo ebaleni. Kulo nyaka, iingcali ziqikelela impumelelo eninzi enokuguqula amandla ebhetri ye-lithium-ion.
Inkqubela phambili eqaphelekayo ekufuneka uyibeke iliso kuphuhliso lweebhetri zombuso oqinileyo. Ngokungafaniyo neebhetri zelithium-ion zemveli ezisebenzisa i-electrolyte engamanzi, iibhetri eziqinileyo zisebenzisa izinto eziqinileyo okanye iiseramikhi njengee-electrolytes. Olu lutsha alunyusi nje ubuninzi bamandla, olunokwandisa uluhlu lwee-EVs, kodwa lunciphisa ixesha lokutshaja kunye nokuphucula ukhuseleko ngokunciphisa umngcipheko womlilo. Iinkampani ezibalaseleyo ezifana ne-Quantumscape zigxile kwiibhetri ze-lithium-metal ze-lithium, ezijolise ekuzidibaniseni kwizithuthi kwasekuqaleni kwe-2025[1].
Ngelixa iibhetri zombuso oqinileyo zinesithembiso esikhulu, abaphandi bajonga ezinye iikhemistri ukujongana neenkxalabo malunga nokufumaneka kwezinto eziphambili zebhetri ezifana ne-cobalt kunye ne-lithium. Ukufuna ngexabiso eliphantsi, ukhetho oluzinzileyo luqhubeleka nokuqhuba inguqulelo entsha. Ngaphaya koko, amaziko emfundo kunye neenkampani kwihlabathi jikelele zisebenza ngenkuthalo ukuphucula ukusebenza kwebhetri, ukwandisa umthamo, ukukhawulezisa isantya sokutshaja, kunye nokunciphisa iindleko zokwenziwa[1].
Iinzame zokwandisa iibhetri ze-lithium-ion zanda ngaphaya kwezithuthi zombane. Ezi bhetri zifumana usetyenziso kwindawo yokugcina umbane kumgangatho wegridi, okuvumela ukudityaniswa okungcono kwemithombo yamandla ahlaziyekayo okwethutyana njengelanga kunye namandla omoya. Ngokusebenzisa iibhetri ze-lithium-ion zokugcina igridi, ukuzinza kunye nokuthembeka kweenkqubo zamandla avuselelekayo ziphuculwe kakhulu [1].
Kwimpumelelo yamva nje, izazinzulu zaseLawrence Berkeley National Laboratory ziye zaphuhlisa i-polymer coating ebizwa ngokuba yi-HOS-PFM. Oku kugquma kwenza ukuba ixesha elide, iibhetri ze-lithium-ion ezinamandla ngakumbi kwizithuthi zombane. I-HOS-PFM ngaxeshanye iqhuba zombini ii-electron kunye nee-ion, iphucula uzinzo lwebhetri, iintlawulo zentlawulo / zokukhupha, kunye nobomi bubonke. Ikwasebenza njengento yokuncamathelisa, enokuthi yandise umndilili wobomi beebhetri ze-lithium-ion ukusuka kwi-10 ukuya kwi-15 iminyaka. Ngaphaya koko, i-coating ibonise ukusebenza okungaqhelekanga xa isetyenziswa kwi-silicon kunye nee-electrode ze-aluminium, ukunciphisa ukuthotywa kwazo kunye nokugcina umthamo webhetri ephezulu kwimijikelo emininzi. Ezi ziphumo zibambe isithembiso sokwandisa kakhulu uxinano lwamandla ebhetri ye-lithium-ion, ezenza ukuba zifikeleleke kwaye zifikeleleke kwizithuthi zombane[3].
Njengoko ihlabathi lizama ukunciphisa ukukhutshwa kwegesi ye-greenhouse kunye nenguqu kwikamva elizinzileyo, ukuqhubela phambili kubuchwepheshe bebhetri ye-lithium-ion kudlala indima ebalulekileyo. Uphando oluqhubekayo kunye neenzame zophuhliso ziqhubela ishishini phambili, lisisondeza kwizisombululo zebhetri ezisebenza ngokufanelekileyo, ezifikelelekayo, kunye nokusingqongileyo. Ngokuphumelela kwiibhetri zombuso oqinileyo, ezinye iikhemistri, kunye neengubo ezifana ne-HOS-PFM, ukubanakho ukwamkelwa ngokubanzi kwezithuthi zombane kunye nokugcinwa kwamandla egridi kuya kuba yinto enokwenzeka.
