摘要/Abstract

摘要： 用电解法制备一种掺杂铋的改性二氧化锰材料（Ｂｉ－ＥＭＤ）．通过ｘ射线衍射及光电子能谱分析，Ｂｉ－ＥＭＤ属于γ－ＭｎＯ＿２，Ｂｉ以Ｂｉ＿２Ｏ＿３形式存在于改性材料中，且材料中Ｂｉ含量随电解时Ｂｉ￣（３＋）浓度增加而增加．当电解液中Ｂｉ￣（３＋）浓度为０．００８ｍｏｌ·Ｌ￣（－１）时，材料中Ｂｉ含量高达１４．３％（重量百分比）．用Ｂｉ－ＥＭＤ装配成ＡＡ型Ｚｎ／ＭｎＯ＿２试验电池．通过循环寿命实验，Ｂｉ－ＥＭＤ表现出良好的可逆性．

Abstract: A modified electrolytic manganese dioside doped with Bi(Bi-EMD)wasprepared and examined by XRD and XPS.It is predominantly γ-mnO_2 and the Bi exists as Bi_2O_3 inthe modified material.The content of Bi in Bi-EMDs increased with the increasement of Bi￣(3+)concentration in electrolyte,and reached14.3(wt)% from the bath of 0.008 mol·1￣(-1)Bi￣(3+)+ used.Some Zn /Bi-EMD prototype batteries of AA size were assembled,and which cycle life tests showedthat the Bi-EMD has better reversibility.
