This week (December 26-31, 2025), the solid-state battery sector achieved breakthroughs in capital, capacity, application, and standards. On the industry side, the signing of leading projects, the commissioning of GWh-level production lines, and the delivery of semi-solid-state car models signaled an acceleration in industrialisation. On the technical front, innovations such as sulphide electrolytes, composite functional layers, and sodium-ion batteries continued to emerge. On the policy front, the first national standard for automotive applications was initiated, laying a foundation for standardized industry development, and the industry chain ecosystem became increasingly well-established.
