NPC Deputy Hu Chengzhong: Proposal to Accelerate the Formulation of National Standards for Solid-State Batteries

Hu Chengzhong, a deputy to the National People’s Congress and Chairman of the Board of Directors of Delixi Group, submitted seven proposals covering areas including solid-state batteries. He proposed accelerating the formulation and implementation of a series of national standards for automotive solid-state batteries, and issuing performance specifications, safety specifications, and lifespan specifications as soon as possible; optimizing the direction of policy support by shifting from large-scale subsidies to targeted support, with a focus on supporting technological breakthroughs in key links such as electrolyte materials and production equipment; and launching solid-state battery application demonstration projects to accelerate technology popularization and market cultivation.

Conclusion: This week, the solid-state battery industry remained exceptionally lively. Enterprises such as Sunstone Development and TONZE made it clear that their sulphide projects were still in the early R&D stage, indicating that technological breakthroughs on the upstream materials side still required time; meanwhile, Qingtao Energy advanced its two major bases in Wuhai and Taizhou simultaneously, CORNEX New Energy filed two projects for solid-state production lines, Suzuki’s acquisition of Kanadevia accelerated technology integration, and Yaoshi Lithium Battery completed 200 million yuan in financing, showing that the industrialisation process of top-tier enterprises had clearly accelerated. With proposals from NPC Deputy Hu Chengzhong and other entrepreneurs, the formulation of national standards for solid-state batteries was expected to accelerate, and the industry was likely to move from policy-driven development toward standardized development at a faster pace.

According to SMM forecasts, all-solid-state battery shipments will reach 13.5 GWh by 2028, while semi-solid-state battery shipments will reach 160 GWh. Global lithium-ion battery demand is projected to reach approximately 2,800 GWh by 2030, with the EV sector's lithium-ion battery demand showing a CAGR of around 11% from 2024 to 2030, ESS lithium-ion battery demand at a CAGR of about 27%, and consumer electronics lithium battery demand at a CAGR of roughly 10%. Global solid-state battery penetration is estimated at about 0.1% in 2025, with all-solid-state battery penetration expected to reach around 4% by 2030, and global solid-state battery penetration potentially approaching 10% by 2035.
