Abstract
A negative electrode particle and a preparing method thereof, a negative electrode sheet, and an energy-storage apparatus are provided. The negative electrode particle provided in the disclosure defines a closed pore located inside the negative electrode particle and an open pore located on a surface of the negative electrode particle. A ratio of a pore volume C1 of the closed pore to a pore volume C2 of the open pore satisfies: 6≤C1/C2≤11, and the pore volume C1 of the closed pore satisfies: 0.03 cm/g≤C1≤0.12 cm/g.
