Iibhetri zeLithium-ion zineenzuzo zomthamo omkhulu, ubomi bomjikelezo omde, kwaye akukho nkumbulo. Ziye zaba yibhetri ekhethiweyo kwimveliso ye-electronics yabathengi behlabathi jikelele kunye nebhetri eqhelekileyo yezithuthi zamandla amatsha.Ubuninzi bamandla obuninzi kunye nokutshaja ngokukhawuleza ziindlela ezingenakuphepheka ekuphuhliseni iimveliso zebhetri ye-lithium. Ukongeza i-conductive agents kwizinto eziphathekayo ze-electrode yindlela efanelekileyo yokuphucula ukusebenza kweebhetri ze-lithium.
Inokunyusa kakhulu iipropathi eziqhubayo zee-electrode ezilungileyo nezingalunganga, yandise umthamo webhetri umthamo wamandla, kwaye inciphise ukuxhathisa. , ukwandisa ukuchithwa kwe-deintercalation kunye nokufakwa kwesantya se-lithium ion, ukuphucula kakhulu intlawulo yebhethri kunye nokusebenza kokukhutshwa, kunye nokuphucula ukusebenza ngokukhawuleza kokutshaja kwezithuthi zombane. izinto kwi-electrode yebhetri.

Kwithiyori, i-graphene electrode inokuba kabini umthamo othile wegraphite. Ukongeza, ukuba igraphene kunye nekhabhoni emnyama zixutywe kwaye zongezwa njengezongezo eziqhubayo kwiibhetri ze-lithium, ukuchasana kwangaphakathi kwebhetri kunokunciphisa ngokufanelekileyo, kunye nentlawulo yezinga lebhetri kwaye ukukhutshwa kokusebenza kunye nobomi bomjikelezo unokuphuculwa.
Ngaphezu koko, ukugoba kwebhetri akunampembelelo kwintlawulo kunye nokusebenza kokukhutshwa, ngoko ke i-electrodes yenziwe ngegraphite. Emva kwemathiriyeli yegraphene, ibhetri inexabiso eliphezulu lokutshaja kunye nesantya sokukhupha, yiyo loo nto iibhetri zegraphene zitshaja ngokukhawuleza.
