BORON-DOPED GRAPHENE SHEET AS SODIUM-ION BATTERY ANODE

摘要

A sodium-ion battery having a boron-doped graphene sheet as an anode active material is provided. The boron-doped graphene sheet is of formula B_xC_y, where x and y satisfy a relation of x+y=4, and x is a number larger than 0 and less than or equal to 1.
