Anode, Anode Dam Coating Composition, and Lithium Secondary Battery

Abstract

A negative electrode for a lithium secondary battery includes a negative electrode current collector, a negative electrode active material layer disposed on one or both sides of the negative electrode current collector, and a dam coating layer disposed on the one or both sides of the negative electrode current collector. The dam coating layer is in surface contact with an end of the negative electrode active material layer and includes a hydrophobic powder, a cellulose-based compound, a rubber-based binder, and inorganic particles. Also provided is a composition for coating a negative electrode dam. The composition for coating a negative electrode dam has excellent surface tension and adhesion, thereby inhibiting the occurrence of a fat-edge of the negative electrode. The dam coating layer formed from the composition for coating a negative electrode dam has the effect of reducing the sliding length of the negative electrode active material layer.
