The anion exchange strategy towards mesoporous α-Ni(OH)₂ nanowires with multinanocavities for high-performance supercapacitors

Abstract

By exploiting a facile and controllable anion exchange strategy, mesoporous α-Ni(OH)2 nanowires with multinanocavities in surfaces have been successfully developed. The novel nanoscale morphology has been proven to be responsible for their excellent capacitive performances.
