| 摘 要： | 采用化学法制备改性二氧化锰,并对其进行了化学分析以及循环伏安扫描研究,结果表明:深度放电及浅度放电度表现出良好的可允性.掺铋改性二氧化锰将二电子放电反应提前进行,掺铋、镍改性化锰则将二电子放电子放电反应推至低电位进行.氧化还原过程中没有不可逆产物生成.

| Abstract: | Modified manganese diocide has been prepared chemically and its properties of chemistry and cyclic voltammetry has also been studied. Experimental results indicate that the chemically modified manganese dioxide has excellent rechargeability both in deep and shallow discharge regions. The sample doped bismuth makes the two-electron discharge reaction carry out in advance, while the sample doped bismuth and nickel markes the two-electron discharge reaction carry out at low potential. The results also show that there are no unrechargeable products generated during the redox reaction. |
