💡 Novelty & Significance:
This review uniquely highlights polychalcogenide generation and shuttling as a critical, overlooked degradation pathway in transition metal chalcogenide anodes for alkali metal ion batteries. It systematically links polychalcogenide formation to cascading failure mechanisms, elucidates governing factors and inhibition strategies, and offers design perspectives for anodes and electrolytes, advancing practical TMC anode development beyond classical volume expansion and kinetics issues.
