Solid state battery development trend is strong, China's patent layout has overtaken Japan

As of May 27, from the perspective of technical sources (patent applicants), Japan is still the world's largest country in the field of solid-state battery patent applications, accounting for nearly 40% of the global patent applications, China ranked second, accounting for about 26.6%. However, from the perspective of the layout market (where patent applications are located), China is the world's largest market for solid-state battery patent layout, accounting for about 31.4%. Japan followed with about 27 percent.

According to the China Automotive power battery Industry Innovation Alliance news, from January to April, China's semi-solid battery was loaded, and the loading capacity was 1138.8MWh, and the supporting battery enterprises were Weilan new energy.

Solid state batteries have a strong development trend, the amount of loading has increased, and the layout of technological research and industrialization has also continued to improve.

According to smart Bud news, in the past two years, China has made significant progress in solid-state battery patent applications and layout, and even surpassed Japan in patent layout. As of May 27, from the perspective of technical sources (patent applicants), Japan is still the world's largest country in the field of solid-state battery patent applications, accounting for nearly 40% of the global patent applications, China ranked second, accounting for about 26.6%. However, from the perspective of the layout market (where patent applications are located), China is the world's largest market for solid-state battery patent layout, accounting for about 31.4%. Japan followed with about 27 percent.

According to the "White Paper on the Development of China's solid-state Battery Industry (2024)" jointly released by EVTank, Ivey Economic Research Institute and China Battery Industry Research Institute, all-solid-state batteries are still facing ion conductivity problems, solid-state interface problems and cycle performance problems that have not been fully solved. It is expected that its industrialization time node will be around 2030.

Based on the research and judgment of the solid-state battery technology route and cost reduction path, EVTank expects that by 2030, the global shipments of solid-state batteries will reach 614.1GWh, the penetration rate of the overall lithium battery is expected to be about 10%, and the market size will exceed 250 billion yuan, mainly for semi-solid-state batteries.
