Phakathi nokuthuthuka okusheshayo kobuchwepheshe bamandla, ukukhethwa kwesayensi kwezinto zebhethri kuthinta ngokuqondile ukusebenza kwebhethri, ukuphepha, kanye{0}}nokusebenza kahle kwezindleko. Kusukela kumishini kagesi yabathengi ukuya ezimotweni zikagesi ukuya{2}}kumasistimu okugcina amandla amakhulu, izimo zohlelo lokusebenza ezihlukene zibeka izidingo ezihlukene ezintweni zebhethri, okwenza ukukhetha okufanele kwezinto zebhethri kubaluleke kakhulu.
Okokuqala, ukuminyana kwamandla kuwukucatshangelwa okubalulekile. Amabhethri e-Lithium-ion ayinketho ekhethwayo kumadivayisi aphathekayo ngenxa yomthamo wawo othize ophezulu (isibonelo, umthamo wethiyori we-lithium cobalt oxide cathodes cishe u-140 mAh/g). Nakuba i-lithium iron phosphate (LFP), kuyilapho inesisindo esiphansi samandla (cishe i-160 mAh/g), isetshenziswa kabanzi ezimotweni zamandla amasha ngenxa yokuzinza kwayo okushisayo nempilo yomjikelezo omude. Okwesibili, ukuphepha kubalulekile. Izinto ze-ternary (njenge-nickel-cobalt-manganese (NCM)) zinamandla amakhulu kodwa zijwayele ukukhululwa komoyampilo emazingeni okushisa aphezulu, okudala ingcuphe yokuphuma kokushisa. Ngokuphambene, izinto ze-lithium titanate anode zinikeza ukuphepha okuphakeme futhi zifanele izinhlelo zokusebenza ezidinga izidingo eziqinile zokuzinza.
Izindleko nokusimama kwezinsiza nakho kunomthelela ezinqumweni zezinto ezibonakalayo. Izinsiza ze-cobalt ziyindlala futhi amanani azo ashintshashintsha kakhulu, okwenza imboni ifinyelele emiklamo yamahhala ye-cobalt ({2}}njenge-manganese binary cathodes) noma ukuthuthukisa obunye ubuchwepheshe obufana namabhethri e-sodium{3}}eion. Ngaphezu kwalokho, ukuhambisana kwemvelo kufanele kubhekwe. Emazingeni okushisa aphansi, i-ionic conductivity yama-electrolyte nezinto ze-electrode ziyehla, okwenza kudingeke ukuthi kusetshenziswe izithasiselo (ezifana ne-LiFSI) noma ama-electrolyte aqinile-esimo ukuze kuthuthukiswe ukusebenza kahle.
Ekugcineni, ukukhethwa kwezinto zebhethri kudinga ibhalansi ephelele yamapharamitha okusebenza, izidingo zohlelo lokusebenza, nezimo ze-supply chain. Ngokuthuthuka kubuchwepheshe obufana-namabhethri e-state aqinile{2}}namabhethri e-lithium{2}}esibabule, isayensi yezinto ezibonakalayo izoqhubeka nokuhola ukuqamba okusha embonini yebhethri.
