  • Binder composition, method of producing binder composition, and method of producing all-solid-state battery
    Patent number: 11912853
    Abstract: A binder composition includes a dispersion medium and a group of binder particles. The group of binder particles is dispersed in the dispersion medium. The group of binder particles include a polymer material. The polymer material includes a constitutional unit originated from vinylidene difluoride. The group of binder particles has a number-based particle size distribution. The particle size distribution satisfies the following conditions: “0.19?X?0.26”, “0.69?Y?0.76”, and “0?Z?0.05”. Here, “X” represents a frequency of particles each having a particle size of less than or equal to 40 ?m. “Y” indicates a frequency of particles each having a particle size of more than 40 ?m and less than or equal to 110 ?m. “Z” indicates a frequency of particles each having a particle size of more than 110 ?m and less than or equal to 250 ?m.

  • METHOD FOR PRODUCING COMPOSITE PARTICLE, POSITIVE ELECTRODE, AND ALL-SOLID-STATE BATTERY, AND COMPOSITE PARTICLE, POSITIVE ELECTRODE, AND ALL-SOLID-STATE BATTERY
    Publication number: 20230343961
    Abstract: A composite particle includes a positive electrode active material particle and a coating film. In a method for producing the composite particle, the coating film covers at least a part of a surface of the positive electrode active material particle, the coating film contains a phosphorus compound, and a glass-transition temperature of the coating film is 300° C. or less.
