On September 28, seven Chinese government agencies—the Ministry of Industry and Information Technology, the National Development and Reform Commission, the Ministry of Transport, the Ministry of Commerce, the State Administration for Market Regulation, the National Energy Administration, and the National Railway Administration—jointly issued the "15th Five-Year Plan" for the Development of the New-Type Battery Industry (hereinafter referred to as the Plan).
The Plan explicitly states that by 2030, China's new-type battery industry will achieve steady growth in scale, with all-solid-state batteries reaching initial large-scale application. At the same time, the Plan proposes that new breakthroughs will be made in advanced electrode materials, novel electrolytes, and high-end auxiliary materials, alongside major strides in the research and development of new-system batteries. Additionally, the cycle life of long-life lithium batteries is projected to reach 15,000 cycles, and the product defect rate among leading enterprises will reach the parts-per-billion (PPB) level.
In the section titled "Accelerating Full-Chain Innovative Development," the Plan calls for strengthening research on cutting-edge and common key technologies. It explicitly targets key priorities, including boosting ionic conductivity, enhancing cycle stability, and optimizing costs, to accelerate technical breakthroughs in industrializing all-solid-state batteries.
Building upon this foundation, the Plan sets out a forward-looking strategic layout for next-generation battery systems—such as novel alkali metal-ion batteries, multivalent ion batteries, metal-air/sulfur batteries, multifunctional composite structural batteries, and nuclear batteries—reserving ample space for future technological evolution.
Regarding specific technological pathways, the Plan features a dedicated entry for "Breakthroughs in All-Solid-State Battery Technology" under the column "Enhancement of Common and Key Technologies." It advocates innovative material and process technology solutions for solid-state batteries while smoothing information-sharing channels between basic research and engineering applications. Key focus areas include optimizing interfacial contact, high ionic conductivity, long cycle life, and engineered pressure system design, while promoting the integrated application of high-voltage, high-specific-capacity cathodes with novel lithium metal-based anodes and lithium-free (anode-free) configurations.
In terms of materials, the Plan proposes expanding the mass-production capacity of high-conductivity, high-performance solid electrolyte materials. In the column "Upgrading Advanced Materials and High-End Equipment," it further emphasizes improving the stability and ionic conductivity of solid electrolytes, alongside developing solid electrolytes with high air stability—such as sulfides and halides—as well as high-performance polymer composite solid electrolytes.
On the equipment front, the column proposes developing specialized machinery for solid-state batteries, including isostatic presses. Regarding products, the Plan calls for elevating the industrialization capabilities of all-solid-state batteries, aqueous batteries, and ultra-fast charging batteries. In terms of system integration, it requires developing customized thermal management solutions based on the unique technical characteristics of new battery types, such as solid-state, sodium-ion, and flow batteries.
Beyond technology and industrial segments, the Plan outlines strategic arrangements for standards and intellectual property (IP). Regarding standards, it urges advancing the formulation of standards in key sectors of new battery types, including all-solid-state and sodium-ion batteries. On IP, it proposes strengthening patent portfolio layouts in critical core technologies—such as all-solid-state batteries, high-capacity long-life energy storage batteries, and high-specific-energy sodium-ion batteries—to build up a robust reservoir of high-value patents.
Overall, the Plan sets out a systematic roadmap for all-solid-state battery development, spanning key technology breakthroughs, electrolyte and electrode materials, manufacturing equipment, product industrialization capabilities, thermal management, as well as standards and patent portfolio layouts.
