An integrated, flexible aqueous Zn-ion battery with high energy and power densities

Energy storage devices are usually stacked from two electrodes and a sandwiched separator. The possible delamination of the stacked structure could deteriorate the electrochemical performance under deformed states. Here the cathode (polyaniline) and anode (metal Zn) are separately electrodeposited on a filter paper coated with current collectors to produce an integrated aqueous Zn-ion battery. High energy and power densities of 175.1 mWh/[email...
