Abstract:
An anode includes an anode current collector and an anode active material layer provided on the anode current collector, and the anode active material layer includes a first anode active material, a second anode active material, and an anode binder. The first anode active material includes a first central portion and a first coating portion provided on a surface of the first central portion. The first central portion includes a material that includes carbon as a constituent element, and the first coating portion includes a polyacrylate salt. The second anode active material includes a second central portion and a second coating portion provided on a surface of the second central portion. The second central portion includes a material that includes silicon as a constituent element, and the second coating portion includes a polyacrylate salt. The anode binder includes one or more of styrene butadiene rubber, readily water-dispersible polyvinylidene fluoride, and carboxymethylcellulose. A ratio of a weight of the polyacrylate salt included in the anode active material layer to a weight of the anode active material layer is in a range from 0.1 wt % to 0.8 wt % both inclusive.

Claim (Index 3):
