Abstract
The present application provides a composite separator, an electrochemical energy storage apparatus, and an electrical apparatus. The composite separator provided in a first aspect of the present application may comprise: a first base film and a second base film; and an anode protection layer located between the first base film and the second base film in a thickness direction of the composite separator, for capturing transition metal ions. The anode protection layer for capturing transition metal ions may be arranged between the first base film and the second base film to prevent the anode protection layer from falling off from an outer surface of the base films during prolonged use, so that the anode protection layer can have more stable anode protection effects in prolonged use of the electrochemical energy storage apparatus, and improve the application performance of the electrochemical energy storage apparatus.
