摘要: Abstract Porous nickel foam is used as a substrate for the development of rechargeable zinc//polyaniline battery, and cathode electrophoresis PANI microparticles in non-aqueous solution applied to fabrication Ni supported electrode, which corrosion prohibited. The with high loading prepared by electrophoretic deposition, followed slurry casting under vacuum filtration. electrochemical charge storage performance material significantly improved using via interlayer. specific capacity foam-PANI electrode layer higher than composite without layer, reaches up 183.28 mAh g −1 at working current 2.5 mA cm −2 . present deposition method plays facile procedure immobilization onto surface non-platinum metals, it becomes feasible use Zn/PANI battery weak acidic electrolyte.
