Hierarchical porous Co3O4 nanosheet arrays directly grown on carbon cloth by an electrochemical route for high performance Li-ion batteries

Co3O4 nanosheet arrays (NSAs) were successfully grown on flexible carbon cloth (CC) by a simple electrochemical deposition method. The deposited films were composed of homogeneous ultrathin hierarchical porous Co3O4 nanosheets. Such Co3O4 NSAs/CC electrodes showed superior electrochemical performance, indicating a promising method to fabricate flexible electrodes for Li-ion batteries.
