Claim:
1. An anode for a lithium secondary battery comprising: a composite anode active material comprising a binder disposed on the composite anode active material, the binder comprising one or more selected from a polyimide, a polyamideimide, a polyamide, and a polyetherimide, wherein the water-soluble polymer comprises one or more selected from carboxymethyl cellulose, a carboxymethyl cellulose salt, methyl cellulose, hydroxymethyl cellulose, hydroxypropyl cellulose, ethyl cellulose, polyvinyl alcohol, polyacrylic acid substituted with an alkaline earth metal cation, polyacrylic acid substituted with an alkali metal cation, polyacrylic acid substituted with an ammonium ion, a poly(alkylene-maleic anhydride) copolymer, a poly(alkylene-maleic acid) copolymer salt, polyethylene oxide, alginic acid, hyaluronic acid, a pectic acid salt, a hyaluronic acid salt, and an alginic acid salt, and wherein the water-soluble polymer is present in an amount ranging from about 3.6 weight percent to about 20 weight percent, based on a total weight of the composite anode active material.
