Abstract

Selenium (Se) is a promising cathode material in high-energy batteries. However, the polyselenides shuttle effect and large volume change of Se upon cycling as well as the poor ionic and electronic conductivity of Se undermine its cycling and rate performance. Herein, we report a novel Se-based cathode material in which Se is fully encapsulated and attached to the inner shell of hollow-core nitrogen-doped carbon (CNx) nanobelts forming hollow double-shell Se
