۳D nickel nanoparticles decorated with trimetallic hydroxide for asymmetric microsupercapacitor

In the realm of flexible energy devices, we present a supercapacitor design featuring a CoNiMn-OH(CNM-OH) positive electrode on nickel porous substrate. The trimetallic CNM-OH structure provides a highsurface area, short pathway for ion diffusion and low contact resistance between electroactive materials andelectrode. The asymmetric supercapacitor based on CNM-OH/Ni and reduced graphene oxide exhibited amaximum energy density of ۶۱.۷ μWh/cm² and a power density of ۱.۰۴ mW/cm².
