The present invention is a negative electrode material for a lithium battery comprising a carbonaceous negative electrode active material having a specific surface area of 1 m 2 / g or more, a binder made of styrene-butadiene rubber, and carbon fibers having a fiber diameter of 1 to 1,000 nm; And a lithium battery using a negative electrode material having excellent properties, that is, low electrode resistance, high electrode strength, excellent electrolyte solution permeability, high energy density and good fast charge / discharge performance. The said negative electrode material contains the binder which consists of 0.05-20 mass% carbon fiber and 0.1-6.0 mass% styrene-butadiene rubber, and further contains 0.3-3 mass% of thickeners, such as carboxymethyl cellulose. |
