The electrolytic solution includes additives, and the additives include an additive A and an additive B. The additive A forms a film on the surface of the positive electrode and effectively prevents interface side reactions at the positive electrode. Comparing with the additive A, the additive B is preferentially reduced to form a film at the negative electrode, avoiding an increase in impedance and deterioration of cycling dynamic performance, etc., caused by film formation of the additive A on the negative electrode. The combination of the additive A and additive B imparts the battery with a reduced gas production, a higher capacity retention rate and a lower impedance at high temperature.
US11239490B2	Method for producing composite particles for electrochemical device electrode A method for producing composite particles for an electrochemical device electrode is provided. The composite particles include an electrode active material and 0.1 to 10 parts by weight of a binder relative to 100 parts by weight of the electrode active material based on a dry weight, the binder having a glass transition temperature of −30 to 30° C. Tha method comprises a step of adjusting a cumulative 10% diameter (D10 diameter) of the composite particles to 20 μm or more and 100 μm or less in a particle diameter distribution in terms of a volume. The composite particles as a powder have a pressure loss of 5.0 mbar or less and a dynamic repose angle of 20° or more and less than 40°.
