摘要

应用加热蒸发高纯锌粉气相传输法,制备锌多面体微球.产物的结构和形貌经XRD、SEM等测试表征,结果表明与该产物为结晶度较好的直径2~3μm的多面体微球.分别以所制锌微球或市售熔融锌作负极,γ-MnO2纳米线为正极,组装AA型碱性锌锰电池.电化学测试表明以锌微球为负极的碱性锌锰电池能显著提高其放电性能,100 mA下的放电容量达到3.14 Ah,显示出它在高能化学电源领域的应用前景.

Abstract

The zinc polyhedral microspheres were synthesized by evaporation of pure zinc powders via a vapor-transport process.The results characterized by XRD and SEM show that the as-synthesized zinc powders are polyhedral microspheres with the diameter of 2~3 μm.The electrochemical investigation showed that the capacity of the as-assembled AA-size primary alkaline Zn-MnO_(2)battery was increased to 3.14 Ah under the constant discharge current of 100 mA by using the as-deposited microspherical zinc powders as the anode active materials and γ-MnO_(2)nanowires as the cathode active materials,indicating their potential application in high-energy batteries.
