Eminyakeni yamuva nje, amabhethri e-lithium-ion aqhamuke njengobuchwepheshe obubalulekile ekushintsheni ekuvuseleleni imithombo yamandla evuselelekayo kanye nezimoto zikagesi (EVS). Isidingo esanda njalo samabhethri asebenza kahle futhi ashibhile akhuphule intuthuko ebalulekile enkundleni. Kulonyaka, ochwepheshe babikezela ukuphumelela okuningana okungaguqula amakhono amabhethri e-lithium-ion.
Ukuthuthuka okukodwa okuphawuleka ukuze uthole iso ukukhula kwamabhethri wombuso oqinile. Ngokungafani namabhethri we-lithium-ion asebenzisa ama-electrolyte alifuyo, amabhethri e-solid-State asebenzisa izinto eziqinile noma ubumbano njengama-electrolyte. Lokhu okusha akugcini ngokukhulisa ubungako bamandla kuphela, okungenzeka ukunweba ububanzi be-EVS, kepha futhi kunciphisa nesikhathi sokushaja futhi kuthuthukisa ukuphepha ngokunciphisa ubungozi bomlilo. Izinkampani ezivelele ezidumile zigxile kumabhethri e-lithium-state e-lithium-metal, okuhlose ukuzihlanganisa ezimotweni ekuqaleni kuka-2025 [1].
Ngenkathi amabhethri wombuso oqinile ebamba isithembiso esikhulu, abacwaningi bahlola ezinye izikhamithi zamameri ukuze babhekane nezinkinga ngokutholakala kwezinto ezibalulekile zebhethri njenge-cobalt ne-lithium. Ukufuna okushibhile, izinketho ezinzile kakhulu ziyaqhubeka nokushayela izinto ezintsha. Ngaphezu kwalokho, izikhungo zemfundo kanye nezinkampani emhlabeni wonke zisebenza ngenkuthalo ukuze zithuthukise ukusebenza kwebhethri, zikhulise umthamo, zisheshise isivinini sokushaja, futhi kunciphise izindleko zokukhiqiza [1].
Imizamo yokwandisa amabhethri e-lithium-ion anweba ngale kwezimoto zikagesi. Lawa mabhethri athola izicelo kwisitoreji se-Grid-Level kagesi, evumela ukuhlanganiswa okungcono kwemithombo yamandla evuselelekayo evuselelekayo efana nelanga namandla omoya. Ngokufaka amabhethri we-lithium-ion ukuthola isitoreji se-grid, ukuqina kanye nokwethenjwa kwezinhlelo zamandla avuselelekayo zithuthukiswa kakhulu [1].
Esikhathini esisanda kwenziwa, ososayensi eLawrence Berkeley Laboratory I-National Laboratory bathuthukise ukuvumelanisa kwama-polymer owaziwa ngokuthi i-HOS-PFM. Le nhlanganisela inika amandla amabhethri ahlala njalo, anamandla amakhulu we-lithium-ion wezimoto zikagesi. I-HOS-PFM ngasikhathi sinye iqhuba ama-elektroni ama-elektroni nama-ion, ukuthuthukisa ukuqina kwebhethri, amazinga okukhishwa / okukhipha, kanye nempilo yonke. Iphinde isebenze njengokunamathelayo, okungenzeka ukuthi kunwetshwe impilo ephakathi ye-lithium-ion amabhethri kusuka eminyakeni eyi-10 kuye kweli-15. Ngaphezu kwalokho, i-coating ikhombisa ukusebenza okuhlukile lapho isetshenziswa kuma-alectron we-silico kanye ne-aluminium, ukunciphisa ukonakala kwalo nokugcina amandla aphezulu ebhethri ngaphezulu kwemijikelezo eminingi. Lokhu okutholakele kubamba isithembiso sokwandisa kakhulu ukuhlukunyezwa kwamandla kwamabhethri e-lithium-ion, okwenza bakwazi ukufinyeleleka kakhulu futhi bafinyeleleke ezimotweni zikagesi [3].
Njengoba umhlaba ulwela ukunciphisa ukuphuma kwegesi abamba ukushisa kanye noshintsho kwikusasa elizinzile, intuthuko kubuchwepheshe bebhethri le-lithium-ion budlala indima ebaluleke kakhulu. Ukucwaninga okuqhubekayo kanye nemizamo yentuthuko kuqhubekela phambili embonini, kusisondeza izixazululo ezisebenza kahle, ezingabizi futhi zinobungani bezemvelo. Ngokuphumelela kumabhethri wombuso oqinile, ezinye zamakhemikhali, kanye nezimbobo ezinjenge-hos-PFM, amandla okukhulelwa okuphezulu kwezimoto zikagesi kanye nesitoreji samandla se-grid-level kuba lula.
