摘要

The cyclic stability of Cr~(2)O~(3)is very poor due to the large volume change during lithiation/delithiation. In this study, we have found that Cr~(2)O~(3)nanocrystals synthesized by using a simple hydrothermal method can improve its cyclic stability. Sample calcined at 430 °C has uniform size, compact structure and high crystallization degree. These Cr~(2)O~(3)nanocrystals exhibit a stable cyclic performance of 185 mAh g_(−1)after 100 cycles at 100 mA g_(−1). It is useful in real life, such as providing power consumption for minitype device, etc.
