Abstract
A negative electrode material, and a negative electrode plate, an electrochemical device, and an electronic device including the same. The negative electrode material includes SiMC, where 0.5≤x≤2, 0.5≤y≤4, and M includes at least one of boron, nitrogen, oxygen, or aluminum; for SiMC, a particle size at a quantity accumulation degree of A % is DA, a particle size at a volume accumulation degree of B % is DB, and a half-peak width of a quantity distribution curve is ΔD; and 2 μm≤(D50−D50)≤6 μm, and 1≤(D99−D1)/ΔD≤1.3. The use of the negative electrode material, and the negative electrode plate, the electrochemical device and the electronic device including the same according to the present application achieve good cycle performance and energy density.
