CNTs support 2D NiMOF nanosheets for asymmetric supercapacitors with high energy density

Abstract

Besides complex preparation and low-yield synthesis, attaining high energy density while maintaining high power density remains a significant challenge for supercapacitors applications in the field of energy storage. Herein, the...

Three-dimensional ternary NixCuyZnz(CO3)(OH)2 electrodes for supercapacitors: electrochemical properties and applications

“…To identify additional electrochemical properties of the ASC, the energy and power densities were measured using eqn (8) and (9), respectively. 80,81 where E (W h kg −1 ) is the energy density, I (A) is the applied current, is the galvanostatic discharge current area, and M (g) is the total mass. P (W kg −1 ) is the power density, and Δ t (s) is the discharge time.…”
