Enhanced Structural Stability of Nickel–Cobalt Hydroxide via Intrinsic Pillar Effect of Metaborate for High-Power and Long-Life Supercapacitor Electrodes

Layered α-Ni(OH) 2 and its derivative bimetallic hydroxides (e.g., α-(Ni/Co)(OH) 2 ) have attracted much attention due to their high specific capacitance, although their insufficient cycling stability has blocked their wide application in various technologies. In this work, we demonstrate that the c... View More
