MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617091141 A) filed by Terawatt Technology K. K. on July 27, 2026, for Lithium Secondary Battery.
Inventors include Takimoto, Kazuki; and Oyama, Gosuke.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention provides a lithium secondary battery that has excellent cycle characteristics. The present invention relates to a lithium secondary battery that includes: a negative electrode active material that contains Si; and an electrolyte solution. The average particle diameter of the negative electrode active material is 5.0– 30 µm. The electrolyte solution includes LiFSI, LiPF6, and LiPO2F2 as lithium salts. When the mole fraction of LiFSI is x, the mole fraction of LiPF6 is y, the mole fraction of LiPO2F2 is z, and x+y+z=1, 0.05=x=0.95, 0.05=y=0.90, and 0.005=z=0.35. The lithium ion concentration of the electrolyte solution is 0.7–3.0 M.
