Tunable construction of CuS nanosheets@flower-like ZnCo-layered double hydroxide nanostructures for hybrid supercapacitors

Abstract

Layered double hydroxides (LDHs) are favorable materials for supercapacitors thanks to their unique layered structure, high theoretical capacity, and low cost. However, unsatisfactory cyclability and poor conductivity have been recognized...

Unveiling the potential of nanosheet-based NiTe2@MnTe hollow nanospheres in hybrid supercapacitor technology

“…9,10 This is where hybrid supercapacitors, which effectively bridge the gap between supercapacitors and batteries, come into play. [11][12][13][14] By integrating a capacitor-type electrode for high power delivery and a battery-type electrode for high energy provision, hybrid supercapacitors present an optimal solution. 15,16 However, the battery-type electrodes oen lag in performance over extended use due to poor reversibility and sluggish kinetics.…”
