Sulfide-based all-solid-state batteries (ASSBs) are regarded as next-generation high-safety, high-energy-density storage systems owing to the high ionic conductivity of sulfide-based solid-state electrolytes (SSEs), room-temperature processability, and intimate electrode–electrolyte contact. However, under practical operating conditions, performance degradation originating from anode-related instabilities remains a critical bottleneck. In particular, at the anode, the combination of low operating potential and large deformation induces interfacial reactions, contact evolution, and transport heterogeneity, resulting in their mutual amplification. Despite growing interest, studies that systematically synthesize anode-driven degradation in sulfide-based ASSBs from an electro-chemo-mechanical coupling perspective remain relatively limited. 

Accordingly, this review focuses on representative anode configurations, including Li metal, Si-based, and anode-free systems, and analyzes anode-induced degradation mechanisms in sulfide-based ASSBs within an electro-chemo-mechanical coupling framework. Finally, remaining challenges and future research directions toward anode-centric designs that precisely regulate interfacial chemistry, mechanical behavior, and Li+  transport are discussed.
