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. This journal is
