To enhance the cycling stability and conductivity of MnO2 electrodes for supercapacitors, Y-doped ZrO2 coatings on MnO2 electrodes are prepared, so protecting the electrodes and enhancing the electrochemical performance of electrodes in electrolytes.
Unique NiCo2S4@Ni3S2 core–shell nanotube arrays with a hierarchical structure, as promising positive electrodes for supercapacitors, were designed and synthesized on the surface of Ni foam via a hydrothermal reaction and electrodeposition method.
Three-dimensional interconnected CuS nanowalls with rough surfaces on Ni foam were obtained through a facial synthetic route. The binder-free electrode exhibits high electrochemical performance with excellent cycling stability.
Three-dimensional freestanding hierarchically porous carbon was successfully fabricated and assembled in a symmetric supercapacitor presenting outstanding electrochemical performance.
