可充碱性锌锰电池的研究

Study of the Rechargeable Zn/MnO_2 Battery

在电解二氧化锰中加入氧化铋、氢氧化镍、硫酸钡 ,通过循环伏安对其可充性进行研究 ,并且做成AAA型电池进行充放电实验。发现循环伏安测试结果与成品电池测试结果基本吻合。氧化铋、硫酸钡对提高MnO2 的可充性起到了积极的作用 ,但氢氧化镍效果不明显。R03型电池充放电多达30次 。

After adding Bi2O3、Ni(OH)2、BaSO4 into MnO2,the rechargeability of MnO2 through cyclic voltammetry was studied and the charge/discharge performance of the AAA battery was tested. It shows that the consequences of two methods above are very approximate.It found that Bi2O3 and BaSO4 improve the rechargeability of MnO2,but the Ni(OH)2 has no apparent effect on MnO2. AAA battery can provide 7 200mA·h after the 30th cycle test.
