A novel co-precipitation method for one-pot fabrication of a Co-Ni multiphase composite electrode and its application in high energy-density pseudocapacitors

A novel co-precipitation method for one-pot fabrication of a Co-Ni multiphase composite electrode and its application in high energy-density pseudocapacitors

A multiphase composite film composed of nickel(II) hydroxide and cobalt(II) hydroxide was synthesized by a novel co-precipitation method. The film exhibited high capacitance and stable cyclic retention because of its 3D network nanostructure and high conductivity due to CoOOH evolved during cycling.
