Abstract

Uniform amorphous vanadium oxide films were coated on graphene via atomic layer deposition and the nano-composite displays an exceptional capacity of ∼900 mA h g−1 at 200 mAg−1 with an excellent capacity retention at 1 A g−1 after 200 cycles. The capacity contribution (1161 mA h g−1) from vanadium oxide only almost reaches its theoretical value.
