Electrolyte Composition

An electrolyte composition includes: an electrolyte; and an additive composition including: an inhibitor that reduces a topography variation resulting from material deposition on the anode of the battery during the charging process; and/or a leveler that reduces an effect of ion concentration gradient between a plurality of tips of the plurality of branches and the base from material deposition on the anode of the battery during the charging process. This electrolyte composition is for use with a battery including an anode and a cathode during a charging process. The anode includes a base and a plurality of branches protruding from the base and spaced apart from one another along the base to form a gap.
