文摘

N, P doped hierarchical porous carbon as host for high performance sulfur cathode. Highly interconnected structure and suitable porosity benefit Sulfur impregnation. In-situ doping N, P into the carbon induced stronger chemical adsorption ability. Excellent cycling stability with 0.058% capacity decay/cycle for over 500 cycles.
