摘要:
An anode and a lithium battery comprising the same are disclosed. The anode comprises a current collector, and an anode material coated on or filled within the current collector. The anode material comprises a carbon material and an adhesive, and the adhesive comprises a hydrophobic polymer binder and a sodium carboxymethyl cellulose, in which an average molecular weight of the sodium carboxymethyl cellulose ranges from about 10×105 to about 12×105, a substitution degree of the sodium carboxymethyl cellulose ranges from about 0.65 to about 0.9, and the sodium carboxymethyl cellulose ranges from about 0.5% to about 0.7% of the anode material by weight.
