Tunable fabrication of core–shell Ni–MnO₂ hybrid foams through structure-guided combustion waves for binder-free high-performance supercapacitor electrodes

Abstract

Combustion waves passing through hybrids of nickel foams and fuels fabricate tunable core–shell Ni@C (Ni@MnO₂) as a template for binder-free high-performance supercapacitor electrodes.
