"Design strategies of performance-enhanced Se cathodes for Li-Se batter" by Weiling Qiu, Xiang Long Huang et al.
Lithium-selenium (Li-Se) batteries are deemed as an emerging high energy density electrochemical energy storage system owing to their high specific capacity and volume capacity. Prior to their practicality, a series of critical challenges from the Se cathode side need to be overcome including low reactivity of bulk Se, shuttle effect of intermediates, sluggish redox kinetics of polyselenides, and volume change etc. In this review, recent progress on design strategies of functional Se cathodes are comprehensively summarized and discussed. Following the significance and key challenges, various e...
