[Solid-state battery: Qingtao applies for patent on "an all-solid-state battery"] On July 18, 2025, information from the China National Intellectual Property Administration showed that Shanghai SAIC Qingtao Energy Technology Co., Ltd. had applied for a patent named "an all-solid-state battery," with the publication number CN120341248A and the application date in November 2024.
This all-solid-state lithium battery includes a positive electrode, a negative electrode, and a solid-state electrolyte membrane. The anode active material layer comprises doped silicon and doped atoms (the atoms include at least one of B atoms and P atoms), with the mass of doped silicon accounting for more than 90% of the anode layer.
