▎ 摘  要

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 similar to 600 S cm(-1) and low square resistance of 1.6 Omega sq(-1). With the aid of 3D graphene network, the poorly conductive LiFePO4 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.
