Application: Electrode composition, electrode sheet for all-solid state secondary battery, and all-solid state secondary battery, and manufacturing methods for electrode sheet for all-solid state secondary battery and all-solid state secondary battery (Patent ID: US20230369600A1)
The patent filed by Fujifilm Holdings Corp. describes an electrode composition for all-solid state secondary batteries, consisting of specific components such as inorganic solid electrolyte, active material, conductive auxiliary agent, polymer binder, and dispersion medium. The polymer binder includes a polymer binder that is dissolved in the dispersion medium and meets certain conditions related to molecular weight, surface energy, content percentage, and specific surface area. The dispersion medium also has a specific SP value for optimal performance.
Furthermore, the electrode composition can include a polymer binder with a substituent having 8 or more carbon atoms as a side chain, and may also include a second polymer binder with a different molecular weight. The composition's viscosity at different shear rates is also specified for quality control. The patent also covers the use of this electrode composition in an electrode sheet for all-solid state secondary batteries and the manufacturing methods for both the electrode sheet and the battery itself. Overall, the patent aims to provide an improved electrode composition that enhances the performance and efficiency of all-solid state secondary batteries.
