Abstract: An anode active material, and an electrochemical device and electronic device using such anode active material. Also, an anode active material, including graphite. Controlling a graphitization degree of particles of different particle sizes of the anode active material can achieve a balance between kinetic performance and first cycle efficiency of the electrochemical device.
