  "textContent": "The present disclosure relates to the technical field of batteries, and in particular relates to a negative electrode plate and a battery. The negative electrode plate comprises a negative electrode current collector and a negative electrode active coating layer on a surface of at least one side of the negative electrode current collector, wherein the negative electrode active coating layer comprises silicon-based particles; the number of the silicon-based particles in a region of 100 μm×100 μm of the surface of the negative electrode active coating layer is a, 1≤a≤50; the average sphericity of the silicon-based particles is b, 0.66≤b≤1; and a and b satisfy: 1≤a/b≤67, thereby the degree of self-discharge of the battery can be reduced and the high-temperature storage performance of the battery can be improved.",
