Abstract

See full text

An electrode for a lithium battery, which electrode includes an electrode active material which can charge and discharge lithium ions (A), a carbonaceous conductive additive (B) and a binder (C). The carbonaceous conductive additive contains carbon fiber, the carbon fiber including a mixture of two kinds of carbon fibers having different diameter distributions on a number basis; and the fiber diameter distribution of the carbon fiber in the electrode has one or more maximum values at 5-40 nm and at 50-300 nm, respectively. Also disclosed is a lithium battery using the electrode. The electrode enables production of a lithium battery having a reduced discharge capacity decline.
