Zusammenfassung:The present application relates to a negative electrode plate and a battery, and belongs to the technical field of secondary batteries. The negative electrode plate comprises a negative electrode current collector and a negative electrode active material layer, which is arranged on the surface of the negative electrode current collector. An active material in the negative electrode active material layer comprises a flaky silicon-based material, and the included angle between at least 60% of the flaky silicon-based material and the surface of the negative electrode current collector is less than or equal to 20 degrees by taking the surface of the negative electrode current collector as a reference. The flaky silicon-based material of the negative electrode plate tends to be parallel to the negative electrode current collector, and tends to be arranged in parallel and form a stacked structure along the thickness direction of the negative electrode plate, such that the structure can be more stable; during the ch
