ABSTRACT Lithium‐organochalcogenide batteries have the merits of high energy density, eco‐friendliness, and low costs, but facing issues like rapid capacity fading and poor rate capability. Herein, we propose the design and synthesis of an organoselenide‐sulfide hybrid compound by reacting tetramethyl thiuram disulfide with molten selenium disulfide (SeS 2 ). The organoselenide‐sulfide hybrid compound possesses a chain‐like structure, high chalcogen (S and Se) atom ratios, and enhanced conductiv
