Application: Lithium secondary battery and manufacturing method for the same (Patent ID: US20240097130A1)
The patent filed by Nippon Telegraph and Telephone Corp. describes a lithium secondary battery with a positive electrode film, transparent electrolyte, and negative electrode film, all formed on flexible, transparent substrates. The positive electrode film contains a substance capable of a redox reaction with lithium ions, while the negative electrode film contains an organic radical species for the same purpose. The method for manufacturing this battery involves forming the electrode films and electrolyte, as well as charging the battery cell to add a lithium source to the negative electrode film.
The claims detail the specific components and processes involved in the lithium secondary battery, including the use of organic radical species like anthraquinone and phthalimide in the negative electrode film. Additionally, the claims outline the method for manufacturing the battery, which includes steps for adding a lithium source to the negative electrode film and replacing the positive electrode film with one containing specific organic radical species. Overall, the patent focuses on creating a transparent, flexible lithium secondary battery with efficient redox reactions for improved performance.
