Layered double hydroxide（LDH） has widely attracted attention due to its rich active sites and the synergistic ef-fects of bimetallic.However,the preparation of novel LDH electrode materials with high rate performance and low resistance is still a challenge.Three-dimensional nano-flowered zinc-cobalt layered hydroxides（ZnCo LDHs） electrode material grown in situ on nickel foam（NF） current collectors were prepared by co-precipitation method.ZnCo LDHs@NF had large accessible surface area and extremely low inherent resistance（0.56 Ω）.At the same time,the electrode material had high specific capa-city（1 583 F/g at current density of 1 A/g） and could still maintain specific capacity of 81%（1 280 F/g） at current density of 20 A/g.These excellent electrochemical properties indicate that the prepared ZnCo LDHs@NF electrode material has great application prospects in energy storage devices.
