Njengengxenye ebalulekile yezimoto zikagesi, amabhethri e-lithium-ion azoba nomthelela othile wezemvelo ngesikhathi sesigaba sokusebenzisa. Ukuze uthole ukuhlaziya okuphelele komthelela wezemvelo, amaphakethe ebhethri e-lithium-ion, aqukethe izinto ezihlukile eziyi-11, akhethwe njengento yokufunda. Ngokusebenzisa indlela yokuhlola yempilo yempilo kanye nendlela yokungena kwesisindo ukukala umthwalo wezemvelo, uhlelo lokuhlola inkomba oluningi olususelwa kwizici zebhethri lezemvelo.
Ukuthuthuka okusheshayo komkhakha wezokuthutha1 kudlala indima ebaluleke kakhulu entuthukweni yezomnotho nezenhlalo. Ngasikhathi sinye, futhi kudla inani elikhulu lamafutha okugcwala, okwenza ukungcoliswa okukhulu kwemvelo. Ngokusho kwe-Iea (2019), cishe ingxenye yesithathu yokukhishwa kwe-CO2 Global ivela emkhakheni wezokuthutha. Ukuze anciphise isidingo esikhulu samandla kanye nomthwalo wezemvelo wemboni yezokuthutha emhlabeni jikelele, ukufakwa kukagesi embonini yezokuthutha kubhekwa njengenye yezindlela ezibalulekile zokunciphisa ukuphuma okungcolile. Ngakho-ke, ukuthuthukiswa kwezimoto ezinobungane nezemvelo, ikakhulukazi izimoto zikagesi (evs), sekuyindlela ethembisayo embonini yezimoto.
Kusukela ngohlelo lweminyaka eyi-12 (2010-2015), uhulumeni waseChina unqume ukukhuthaza ukusetshenziswa kwezimoto zikagesi ukwenza ihlanzekile yokuhamba. Kodwa-ke, inselelo enzima yezomnotho iphoqe amazwe ukuthi abhekane nezinkinga ezinjengezinkinga zamandla, ukuntuleka kwamafutha aphezulu, ukukhuphuka kwamandla emali, njll., Onke amandla okuthatha izinqumo. Ngakho-ke, ukwamukelwa okuphansi nokwamukelwa kwezimoto zikagesi kuvimbela ukutholwa kokuqala kwezimoto zikagesi emakethe.
Ngokuphambene nalokho, ukuthengiswa kwezimoto ezinamandla kaphethiloli kwaqhubeka kwehla, kanye nomkhuba wokukhula ngenani labanikazi behle. Ngamanye amagama, ngokuphoqelelwa kwemithethonqubo kanye nokuvuka kokuqwashisa ngemvelo, ukuthengiswa kwezimoto ezijwayelekile zikaphethiloli sezishintshile okuphambene nokuthengisa kwezimoto zikagesi, kanti izinga lokungena kwezimoto zikagesi likhula ngokushesha. Njengamanje, amabhethri e-lithium-ion (lib) uyisinqumo esihle kunazo zonke emkhakheni wezimoto zikagesi ngenxa yesisindo sazo sokukhanya, ukusebenza okuhle, ukuvela kwamandla aphezulu kanye nokukhipha amandla aphezulu kanye nokukhipha amandla aphezulu. Ngaphezu kwalokho, amabhethri e-lithium-ion, njengobuchwepheshe obusezingeni eliphezulu ngezinhlelo zokugcina ibhethri, futhi banamandla amakhulu ngokuya ngokuthuthukiswa kwamandla okuzinzile kanye nokwehliswa okukhulu ekuphumeni kwekhabhoni.
Ngenqubo yokuphromotha, izimoto zikagesi kwesinye isikhathi zibukwa njengezimoto ezi-zero-ukuphuma, kepha ukukhiqizwa kanye nokusetshenziswa kwamabhethri abo kunomthelela omkhulu emvelweni. Ngenxa yalokho, ucwaningo lwakamuva lugxile kakhulu ezinzuzweni zezemvelo zezimoto zikagesi. Kunocwaningo oluningi ngezigaba ezintathu zokukhiqiza, ukusetshenziswa kanye nokulahlwa kwezimoto zikagesi, zithathe ezintathu ze-lithium nickel cobalt manganete mageate (NCP) nama-lithium iron phosphate mamakethe yemoto yaseChina njengendaba yokufunda futhi eqhuba ukuhlaziya okukhethekile. Kulawa mabhethri amathathu asuselwa ekuhlolweni komjikelezo wempilo (LCA) wezigaba zokukhiqiza, ukusetshenziswa nokuphinda usebenzise amabhethri e-traction. Imiphumela ikhombisa ukuthi ibhethri le-Lithium Iron Phosphate linokusebenza okungcono kwezemvelo kunezimo ezijwayelekile, kepha ukusebenza kwamandla esigabeni sokusebenzisa akukuhle njengebhethri kathathu, futhi kunenani eliningi lokuphinda usebenzise kabusha.
