Key Findings
KnowMade, a specialist in patent analysis, has released an updated report on intellectual property (IP) trends in the all-solid-state lithium-ion battery sector for Q2 2026. According to this report, over 2,250 new patent families were published worldwide during the quarter, indicating a surge in research, development, and protection activities related to solid-state battery technology. Notably, key players such as China’s CATL and Gotion, South Korea’s POSCO, and China’s Chery Automobile have substantially increased their patent filing activities compared to their average in Q2 2025.
Technical and Clinical Details
KnowMade’s analysis focuses on innovative technologies across key components of solid-state batteries, including solid electrolyte materials (sulfide, oxide, polymer-based), electrode materials, cell structures, manufacturing processes, and safety aspects. Many new patents aim to improve performance, reduce costs, and establish mass production techniques in these areas. For instance, the intensified patenting by CATL and Gotion suggests their ambition to establish a leading role in the next-generation solid-state battery market. POSCO’s activities are likely concentrated on strengthening IP in material supply, especially for cathode, anode, and electrolyte materials. Furthermore, the increase in patent activities by automaker Chery Automobile reflects its accelerated technological development to integrate solid-state batteries into its EV lineup.
Background and Industry Context
All-solid-state batteries are anticipated as the ultimate battery technology to solve the challenges associated with existing lithium-ion batteries (safety, energy density, charging speed). Companies and research institutions worldwide are engaged in fierce development competition. The surge in patenting activity is a critical strategy for companies to secure technological advantages and establish future market competitiveness. The fact that Chinese and South Korean companies, in particular, are strengthening their IP activities indicates their aspiration for global leadership in the battery technology sector. The publication of over 2,250 new patent families underscores the rapid pace and scale of technological innovation in this field.
Strategic Significance and Outlook
The acceleration of patenting activity in all-solid-state lithium-ion batteries suggests that this technology will mature further and advance towards commercialization in the coming years. As major players strengthen their IP portfolios, technological competition will intensify, driving further innovation. Analysis of patent information serves as a crucial indicator for investors and researchers to identify technological leaders and hot spots within specific technical domains. Ultimately, these patents are expected to materialize into practical products, establishing new standards for battery technology in electric vehicles, renewable energy storage, and other high-performance applications.
