"Two-in-one shell configuration for bimetal selenides toward fast sodiu" by Zichao Yan, Lingfei Zhao et al.
The shell structure design has been recognized as a highly efficient strategy to buffer the severe volume expansion and consecutive pulverization of conversion-type anodes. Nevertheless, construction of a functional shell with a stabilized structure that meets the demands of both high electronic conductivity and feasible pathways for Na+ ions has been a challenge so far. Herein, we design a two-in-one shell configuration for bimetal selenides to achieve fast sodium storage within broadened voltage windows. The hybridized shell, which benefits from the combination of titanium dioxide quantum do...
