Abstract

The present application relates to an active material, a negative electrode sheet, a battery and electric equipment. The active material has a first stability coefficient α1 and a second stability coefficient α2, and the active material satisfies the following relationships: α1 = Dv50 - Dv50', 0 ≤ α1 ≤ 1 µm; and α2 = Dn50 - Dn50', 0 ≤ α2 ≤ 0.04 µm; wherein Dv50 is a particle size of the active material measured when a cumulative volume fraction in volume-based distribution reaches 50%, Dv50' is a particle size of the active material measured when a cumulative volume fraction in volume-based distribution reaches 50% after a 5-ton powder compaction test; Dn50 is a particle size of the active material measured when a cumulative number fraction in number-based distribution reaches 50%; and Dn50' is a particle size of the active material measured when a cumulative number fraction in number-based distribution reaches 50% after a 5-ton powder compaction test.
