The cycling behaviors of and powders, which were synthesized by chemical reduction and combined with a binder and a conductive additive to produce composite electrodes, are presented. The cycling stability of the electrode increased with decreasing particle size, and was higher for the multiphase material than for the single‐phase material of comparable particle size. The higher cycling stability of is explained by the subsequent reaction of the constituent phases and the mechanism of the reaction of with , and is discussed with respect to other multiphase materials which have been reported in the literature. The best‐performing material was of particle size , yielding about 200 cycles for galvanostatic, charge‐limited cycling. ©1999 The Electrochemical Society
