摘要: Abstract A novel self-assembled LiFePO 4 /graphene composite is successfully prepared by a facile template-free hydrothermal approach. Physical and electrochemical properties of the as cathode material in rechargeable hybrid aqueous batteries are firstly investigated. The exhibits high discharge capacity 145.8 mAh g −1 at 0.2 C, which 40% higher than that pristine . Moreover, shows much better rate capability excellent cyclability. This enhanced performance could be attributed to positive effects graphene nanosheets, create flexible electrical conductive matrix, ensuring continuous electron pathway bulk electrode absorbing volume change during lithium intercalation/de-intercalation
