💡 Novelty & Significance:
This work reveals how deep sodiation degrades TiS₂ anodes via reactive Ti precipitation causing electrolyte attack and internal stress-driven framework disintegration. Encapsulating TiS₂ nanosheets in dense carbon spheres buffers volume expansion and isolates active Ti, enabling 98.5% retention over 1800 cycles. It clarifies TMD failure mechanisms and offers a structural engineering strategy for stable conversion anodes.
