| Popis: |
The Co-B amorphous alloys were prepared via a chemical reduction method by sodium borohydride, using three different cobalt salts (CoCl2·6H2O, CoSO4·7H2O, and Co(NO3)2·6H2O) as sources of cobalt. As anode materials in alkaline rechargeable batteries, the Co-B alloy prepared from CoCl2·6H2O has a maximum specific discharge capacity of 844.6 mAh/g, and 306.4 mAh/g is retained even after 100 cycles at a discharge current of 100 mA/g. When Co(NO3)2·6H2O is used as a raw material, the formation of Co3(BO3)2 worsens the electrochemical properties of the sample, i.e., a maximum capacity of only 367.0 mAh/g. |
