Abstract

In this paper, three-dimensional (3D) graphene network was prepared by chemical vapor deposition (CVD) on 3D porous Ni template. The as-prepared 3D graphene showed high conductivity of ∼600 S cm −1 and low square resistance of 1.6 Ω sq −1. With the aid of 3D graphene network, the poorly conductive LiFePO 4 exhibited high conductivity and good rate performance of 109 mA h g −1 at 10 C, indicating potential application in high rate lithium ion batteries.
