Abstract
According to an embodiment, a lithium ion battery includes an anode having an active material, a conductive additive, and a binder including carboxymethyl cellulose, styrene-butadiene rubber, and magnesium-alginate at a ratio of 1.5:1.5:1 such that the specific capacity of the anode is 350 mAh/g to 365 mAh/g and an internal resistance of the anode is 65 mΩ to 75 mΩ. The lithium ion battery further includes a cathode, and a separator between the anode and cathode.
