Novel agaric-derived olive-like yolk–shell structured MnO@C composites for superior lithium storage†
Abstract
Unique hierarchical olive-like yolk–shell structured MnO@C composites were customized via an ingenious and effective biomass strategy. This structure, with internal void spaces, accommodated the volume variations of MnO, and the N-doped porous carbon shells ensured the rapid transport of Li+/electron species. When used as anodes for LIBs, ultrastable rate and cycling performances were obtained.
