[Solid-State Battery Rumor Refuted: CATARC's Wang Fang Says No Compliance Determination Was Made on Solid-State Battery Enterprises] On September 4, 2026, Wang Fang, Chief Scientist at the China Automotive Technology and Research Center (CATARC), clarified recent rumors at the "2026 World Power Battery Conference": CATARC has not conducted any determination on solid-state battery enterprises, and the related rumors are "false information." Recently, there were market reports claiming that CATARC, based on the national standard GB/T 43568-2026 "Solid-State Batteries for Electric Vehicles – Part 1: Terminology and Classification," which took effect in July this year, conducted determinations on more than 320 enterprises involved in solid-state batteries, with only 9 ultimately passing all compliance items in full.

[Solid-state battery: Sulphide electrolyte production 70 mt in January-August] From January to August 2026, China's cumulative sulphide electrolyte production reached 70 mt, up 119.7% YoY, already surpassing the full-year 2025 total (58.29 mt). However, this impressive growth masks three harsh realities: ① Only 19.6% of the annual forecast target (360 mt) has been achieved; ② The capacity utilization rate in August was just 5.82%, with capacity severely idling; ③ Product prices continued to plummet (LPSC fell over 24% in a single month). Q4 average monthly production will most likely land in the 11.5-13 mt range, with a full-year total of approximately 118-121 mt, representing a "solid climb." Annual forecast of 360 mt, with only 70 mt completed in the first eight months: the gap between the "mild ramp-up" of China's sulphide electrolyte and reality.

[Solid-state battery: Tianneng Battery achieves large-scale delivery of semi-solid-state 314Ah battery cells, with multi-technology systems making breakthroughs in stages] On 28 August 2026, Tianneng Battery disclosed in its H1 2026 semi-annual report that the semi-solid-state 314Ah battery cells produced in cooperation with WELION New Energy have achieved large-scale batch delivery and have been successfully applied first to grid-side ESS equipment. The company has laid out multiple new-type battery technology routes, including solid-state batteries, sodium-ion batteries and hydrogen fuel cells, and its "lithium-lithium-hydrogen-sodium + solid-state" multi-technology system is accelerating its formation, with the industrialisation process showing a staged progression of "sodium-ion battery demonstration and verification, solid-state battery deployment in multiple scenarios, and accelerated commercialisation of hydrogen fuel". The company's lithium battery business has significantly accelerated its push to go global, with residential ESS outside China as a key breakthrough direction.
