Sumitomo Chemical to Mass-Produce Halide-Based Solid-State Battery Materials in 2028

Expert Views Clash as Hybrid Solid‑Liquid Battery Mass Production Kicks Off in 2026, While All‑Solid‑State Still Builds Momentum

[SMM Analysis: Expert Opinions Clash – Semi-Solid-State Battery Mass Production Year Begins, All-Solid-State Still Building Momentum] 2026 is widely regarded by the industry as the "mass production year" for semi-solid-state batteries. However, expert opinions on the industrial positioning and time pace of semi-solid-state and all-solid-state batteries are markedly divided. SVOLT Energy Technology Chairman Yang Hongxin and Huang Xuejie from the Institute of Physics, Chinese Academy of Sciences, among others, lean toward the view that "semi-solid-state will be the long-term mainstream," while CATL Chairman Zeng Yuqun and Gotion High-tech Chief Scientist Zhu Xingbao remain cautiously optimistic about all-solid-state batteries from the perspectives of technological maturity and cost.

[Solid-State Battery: China–Kazakhstan Perovskite PV and All-Solid-State Energy Storage Research Center Unveiled in Ordos] On July 6, 2026, the China–Kazakhstan Perovskite PV and All-Solid-State Energy Storage Research Center was officially inaugurated at the Ordos New Energy Research Institute. Jointly established by Beihang University, Nazarbayev University of Kazakhstan, and the Ordos New Energy Research Institute, the center will leverage Ordos’ industrial resources and Beihang’s research strengths to promote joint research and technology transfer in perovskite PV and all-solid-state energy storage, building an innovation platform for China–Kazakhstan new energy cooperation. SMM believes that the deployment of large-scale all-solid-state energy storage projects is still more than five years away.
