Abstract

A negative electrode material, a negative electrode sheet, and a lithium-ion battery. The negative electrode material comprises a first negative electrode active material and a second negative electrode active material; the length-to-diameter ratio of the first negative electrode active material is a, and the powder compaction and pressure relief rebound rate is P1; the length-to-diameter ratio of the second negative electrode active material is b, and the powder compaction and pressure relief rebound rate is P2; and P1, P2, a, and b satisfy the relationship: (37*P1 / a+75*P2 / b)＞2.5.
