Reactive milling of graphite with lithium has been performed in order to develop bonding between carbon and lithium atoms and thus to prepare insertion compounds with C/Li molar ratios lower than 6 (C/Li = 6, 4 and 2). A test of these new compounds as anodes of Li batteries has shown higher reversible capacities than graphite (372 mA h/g), weaker hysteresis, and smaller irreversible capacities than milled graphite under the same conditions. This is explained by the formation of a lithiated surface. ©2002 American Institute of Physics.
