Phakathi kwenkqubela phambili ekhawulezayo yobuchwepheshe bamandla, ukhetho lwezenzululwazi lwemathiriyeli yebhetri luchaphazela ngokuthe ngqo ukusebenza kwebhetri, ukhuseleko, kunye-nokusebenza kakuhle kweendleko. Ukusuka kubathengi be-elektroniki ukuya kwiimoto zombane ukuya kwiinkqubo ezinkulu zogcino -ezinkulu, iimeko ezahlukeneyo zosetyenziso zibeka iimfuno ezohlukeneyo kwimathiriyeli yebhetri, isenza ukhetho olufanelekileyo lwemathiriyeli yebhetri ibaluleke kakhulu.
Okokuqala, ubuninzi bamandla yingqwalasela ephambili. Ibhetri yeLithium -yeyona ikhethwayo kwizixhobo eziphathwayo ngenxa yomthamo wazo ophezulu (umzekelo, umthamo wethiyori we-lithium cobalt oxide cathodes umalunga ne-140 mAh/g). Ngoxa i-lithium iron phosphate (LFP), ngelixa inamandla angaphantsi kwamandla (malunga ne-160 mAh / g), isetyenziswa ngokubanzi kwiimoto zamandla amatsha ngenxa yokuzinza kwayo kwe-thermal kunye nobomi bomjikelezo omude. Okwesibini, ukhuseleko lubalulekile. Iimathiriyeli zeTernary (ezifana nenickel-cobalt{8}}manganese (NCM)) zinoxinaniso lwamandla aphezulu kodwa ziqhelene nokukhupha ioksijini kumaqondo obushushu aphezulu, nto leyo ibeka umngcipheko wokubaleka kwe-thermal. Ngokwahlukileyo, izinto ze-lithium titanate anode zibonelela ngokhuseleko oluphezulu kwaye zifanelekile kwizicelo ezifuna iimfuno ezingqongqo uzinzo.
Iindleko kunye nozinzo lwezibonelelo nazo zinefuthe kwizigqibo eziphathekayo. Ubutyebi beCobalt bunqongophele kwaye amaxabiso azo atshintshatshintsha kakhulu, iqhubela ishishini kwi-cobalt{1}}kuyilo lwasimahla (olufana nenickel{2}}manganese binary cathodes) okanye ukuphuhlisa ubuchwephesha obunye obufana neebhetri zesodium{3}}ion. Ngaphaya koko, ukuhambelana nokusingqongileyo kufuneka kuthathelwe ingqalelo. Kubushushu obuphantsi, i-ionic conductivity ye-electrolytes kunye ne-electrode materials iyancipha, nto leyo ebangela ukuba kusetyenziswe izongezo (ezifana ne-LiFSI) okanye eziqinileyo -ze-electrolyte zelizwe ukuze kuphuculwe ukusebenza.
Ekugqibeleni, ukukhethwa kwezinto zebhetri kufuna ibhalansi ebanzi yeeparamitha zokusebenza, iimfuno zesicelo, kunye neemeko zokubonelela. Ngenkqubela phambili kubuchwephesha obufana nebhetri yelizwe-eqinile kunye nebhetri ye-lithium{2}}yesulphur, inzululwazi yemathiriyeli iya kuqhubeka ukukhokela ukuqamba izinto ezintsha kushishino lwebhetri.
