Negative active material composition, method of preparing negative electrode plate by using negative active material composition, and lithium secondary battery manufactured by using the negative active material composition

A negative active material composition including a negative active material, a binder, and a solvent, in which the solvent includes an aqueous solvent and an organic solvent, and a method of preparing a negative electrode plate by using the negative active material composition. A lithium battery manufactured by using the negative active material composition has good lifetime characteristics due to formation of pores in an electrode plate.
