Abstract
The present invention provides an electrode material, for a lithium battery, which is capable of achieving a high-energy density and a high output and continuing its properties for many years, a method of producing the electrode material, and the lithium battery. The electrode material for use in positive and negative electrodes of a lithium battery is formed as a complex by combining a carbon-based conductive material and an electrode active material with each other. The carbon-based conductive material of the electrode material is subjected to hydrophilic treatment by using a gas containing fluorine gas. The electrode material is formed as the complex by calcining a mixture of the carbon-based conductive material subjected to the hydrophilic treatment and the electrode active material in the presence of fluororesin.
