Enabling Selenium‐Rich Se _x S _y Cathodes to Work in Carbonate‐Based Electrolytes

Carbonate-Based Electrolytes In article number 2102832, Zhen Li, Yunhui Huang and co-workers prepare a series of mesoporous carbon/SexSy composites with covalent Se-S bonds and different Se/S molar ratios and systematically investigate their working mechanism in carbonate-based electrolytes. The inherent synergistic effect of Se and S with the electrochemical performance of the SexSy cathodes is revealed, which provides guidance for the rational design of Li-SexSy batteries.
