  • Negative electrode for secondary battery, secondary battery, battery pack, electric vehicle, power storage system, power tool, and electronic device
    Patent number: 10868327
    Abstract: A secondary battery includes a negative electrode including a plurality of first negative electrode active material particles, second negative electrode active material particles, and a negative electrode binder. The first negative electrode active material particles include a carbon material, and the second negative electrode active material particles include a silicon material. The negative electrode binder includes polyvinylidene fluoride and at least a part of the negative electrode binder is provided on a part of the surface of each of the second negative electrode active material particles. A ratio M2/M1 of an abundance M2 of the negative electrode binder on the surface and in proximity to each of the second negative electrode active material particles to an abundance M1 of the negative electrode binder on the surface and in proximity to each of the first negative electrode active material particles is larger than 1.
    Type: Grant

  • Battery, battery pack, electronic device, electric vehicle, electric storage device and electric power system
    Patent number: 10541389
    Abstract: A battery is provided. The battery includes a power generation element having a through hole; and a cylindrical can housing the power generation element and having at least one thin wall part on a circumferential surface of the cylindrical can. A ratio of a hole diameter of the through hole to an outer diameter of the power generation element is 17% or less. The thin wall part is provided in one or both of regions in a range from 0% to 30% and a range from 70% to 100% from one end of the circumferential surface.
