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 10):
A method of manufacturing a secondary battery comprising, in manufacturing of an anode used for the secondary battery together with a cathode and an electrolytic solution:\n preparing a first water dispersion liquid including a first central portion, a second central portion, a polyacrylate salt, and water to form a first anode active material and a second anode active material, the first central portion including a material that includes carbon as a constituent element, the second central portion including a material that includes silicon as a constituent element, the first anode active material in which a first coating portion including the polyacrylate salt is provided on a surface of the first central portion, and the second anode active material in which a second coating portion including the polyacrylate salt is provided on a surface of the second central portion, preparing a second water dispersion liquid including the first water dispersion liquid and an anode binder, the first water dispersion liquid including the first anode active material and the second anode active material, and the anode binder including one or more of styrene butadiene rubber, readily water-dispersible polyvinylidene fluoride, and carboxymethylcellulose; and supplying the second water dispersion liquid onto an anode current collector, thereby forming an anode active material layer including the first anode active material, the second anode active material, and the anode binder to allow a ratio of a weight of the polyacrylate salt to be in a range from 0.1 wt % to 0.8 wt % both inclusive.
