| 摘 要： | 以晶态V2O5(c-V2O5)为原料,采用熔融淬冷法制取了非晶态V2O5类气凝胶(a-V2O5ARG-like).XRD、EIS、CV和充放电实验结果说明:该样品较c-V2O5有更好的电化学性能;在0.1 C和1 C倍率下放电,其首次放电比容量分别为c-V2O5的1.3倍和1.8倍;循环100次后,容量保持率高达79.5%.

| Abstract: | a-V_2O_5 ARG-like was prepared from c-V_2O_5 by melt quenching method. XRD,EIS,CV and charge-discharge test revealed that the sample achieved better electrochemical performance than c-V_2O_5, its initial discharge specific capacities were 1.3 times and 1.8 times of c-V_2O_5 at rates of 0.1C and 1C discharge and the preservation ratio of capacity still kept 79.5% after 100 cycles. |
