Abstract

En 中文

• Ni doping tunes electrochemical behavior of CuO nanorods. • Electronic structure modification governs charge storage behavior. • Optimal doping enables capacitive-dominated charge storage. • Excess doping enhances conductivity but reduces capacitance. • Balance between conductivity and ion transport determines performance.
