Abstract
A negative active material having a surface mean diameter of the negative active material satisfying: lg(SMD−2)+lg(SMD+2)≥0.4. SMD is a value of the surface mean diameter of the negative active material measured in μm, and falls within a range of 10 to 16; and lg is a frequency. The negative active material enables the electrochemical device to achieve a trade-off between a high energy density and a low degree of lithium plating.
