Solid-state battery stocks rally in China; Shanghai Xiba hits limit-up

The move reads as a concept-driven rotation rather than a company-specific story: gains are spread across battery makers of very different scale and maturity, and the limit-up in Shanghai Xiba sets the tone for the segment. That breadth matters because it signals sentiment clustering around the solid-state theme, not fresh disclosure from any single name. The open question is whether the rally holds beyond a single session or fades once the concept heat passes, and whether the larger listed players sustain gains comparable to the smaller, more speculative names.
