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 14):
An electric vehicle, comprising:\n a secondary battery; a converter that converts electric power supplied from the secondary battery into drive power; a drive section that operates in accordance with the drive power; and a controller that controls an operation of the secondary battery, the secondary battery including a cathode, an anode, and an electrolytic solution, the anode including an anode current collector and an anode active material layer provided on the anode current collector, the anode active material layer including a first anode active material, a second anode active material, and an anode binder, the first anode active material including a first central portion and a first coating portion, the first central portion including a material that includes carbon as a constituent element, and the first coating portion being provided on a surface of the first central portion and including a polyacrylate salt, the second anode active material including a second central portion and a second coating portion, the second central portion including a material that includes silicon as a constituent element, and the second coating portion being provided on a surface of the second central portion and including a polyacrylate salt, the anode binder including one or more of styrene butadiene rubber, readily water-dispersible polyvinylidene fluoride, and carboxymethylcellulose, and 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 being in a range from 0.1 wt % to 0.8 wt % both inclusive.
