The composites show clear, short plateaus in the charge/discharge curves as well as reversible phase transition peaks in cyclic voltammetry for the resulting MoO.sub.2. The electrochemical measurements support the generation of the metal oxide in the resulting composite materials. The generation of molybdenum oxide from Mo.sub.2CT.sub.x is verified from the plateau in Li.sup.+ charge-discharge profile as wells as various characterizations of XRD, XPS, etc. The resulting MoO.sub.2 active material coated on a copper foil shows a Li-ion capacity of 323 mAh/g at 50 mA/g (0.1 C) and 180 mAh/g at 1 A/g (4.0 C) with 85% retention for approximately 300 cycles.
