Spinel Li[Li(1-x)/3CrxTi(5-2x)/3]O-4 compounds have been investigated as anode materials for lithium secondary batteries. Li[Li(1-x)/3 CrxTi(5-2x)/3]O-4 electrodes (0 less than or equal to x less than or equal to 1.0) exhibit a reversible capacity between 163 and 154 mAh g(-1) with excellent cycleability. Increase in the amount of Cr ions substituted for Ti ions in the spinel structure decreases the reversible capacity due to a smaller theoretical capacity, but lowers the area specific impedance (ASI) and increases the rate capability.
