电力设备行业快评报告：电池安全标准升级，固态电池产业化有望加速

Investment Rating - The industry investment rating is "outperforming the market," indicating an expected relative increase of over 10% in the industry index compared to the broader market within the next six months [11]. Core Insights - The new national standard for battery safety, effective from July 1, 2026, introduces significant upgrades in safety requirements, particularly in thermal diffusion, bottom impact, and safety after fast charging cycles [2][3]. - Solid-state batteries are expected to see accelerated industrialization due to their superior safety performance compared to traditional lithium batteries, aligning with the new safety standards [3][9]. - The implementation timeline for new models is set for July 1, 2026, for newly approved models and July 1, 2027, for existing approved models [3]. Summary by Sections New National Standard - The new national standard, GB38031-2025, focuses on critical safety aspects such as thermal diffusion, bottom impact, and fast charging cycle safety, with specific requirements for testing methods and technical standards [2][3]. Solid-State Battery Development - Solid-state batteries are characterized by a wider operating temperature range and better heat resistance, making them less prone to short circuits and capable of meeting the new safety standards [3]. - The transition from laboratory research to factory pilot stages for solid-state batteries is underway, with mass production expected to begin around 2026 [3]. Investment Recommendations - The report suggests focusing on battery and electrolyte manufacturers that are advancing in oxide and sulfide solid-state battery technologies, as well as upstream companies producing key raw materials like zirconia and lithium sulfide [9]. - It also recommends monitoring companies involved in high-nickel cathodes and silicon-based anodes, as these materials are expected to benefit from the application of solid-state electrolytes [9].
