Biomaterial-derived porous carbon doped with heteroatoms as a separator coating for high-energy–density Zn-I batteries
1. | The N, P functionalized porous carbon was synthesized through the carbonization of biomass. |
2. | The functional separator facilitated rapid iodine reduction and evolution, and enhanced ion diffusion kinetics. |
3. | Electrochemical experiments indicated that the shuttling of polyiodide was effectively confined. |
4. | The separator with biochar coating delivered admirable cyclic stability at high iodine loading. |
