Abstract: An electrochemical device, including a cathode; an anode; and an electrolyte. The anode has an anode mixture layer on an anode current collector, the anode mixture layer includes a carbon material as an anode active material, and at least a part of a surface of the anode mixture layer or a surface of the carbon material comprises a polymer compound having Si—C and Si—O bonds. The electrochemical device has improved cycle performance and storage performance.

Abstract: An electrochemical device including a cathode, an anode and an electrolyte. The anode includes an anode active material layer, and the contact angle of the anode active material layer relative to a non-aqueous solvent is not greater than 60° as measured by a contact angle measurement. The electrochemical device has improved cycle performance.
