A Ternary (P, Se, S) Covalent Inorganic Framework as a Shuttle Effect‐Free Cathode for Li–S Batteries

Developing new cathode materials to avoid shuttle effect of Li-S batteries at source is crucial for practical high-energy applications, which, however, remains a great challenge. Herein, a new class of sulfur-containing ternary covalent inorganic framework (CIF), P
