锌空气电池氧化锌废料的电解还原技术

Electrolytic zinc technology for oxide wastes of zinc-air battery

将氧化锌还原成颗粒大小约为10μm的鳞片状电解锌粉,用于制作锌饼。通过通电干燥,减少了干燥时的氧化损耗,放电深度达到锌空气电池用锌粉的89%。电解锌与锌空气电池用锌粉以1∶1的质量比掺混后,放电功率提高到122%。

The oxide zinc was reduced to electrolytic zinc powder with the average particle size of about 10μm, which was use to prepare zinc bricks. A conducting drying method was employed to reduce the oxydic loss during drying process of the electrolytic zinc brick,resulting in an 89% depth of discharge compared to zinc powder for zinc-air battery. The discharge power increased to 122% when the electrolytic zinc and zinc powder in alkaline battery blended in mass ratio of 1： 1.
