Study of a graphene-like anode material in N-methyl-N-propylpyrrolidinium bis(trifluoromethanesulfonyl)imide ionic liquid for Li-ion batteries

► Presented work concerns graphene-like material as an anode in lithium-ion cell. ► Conventional electrolyte was replaced by ionic liquid. ►  Satisfactory capacity of the material working with ionic liquid was obtained. ► Mechanism of Li storage in these materials is determined to be quite complex. ► No well-defined charging/discharging plateau was recorded.
