摘要
在工业用铅酸电池正极铅膏中添加了不同量的石墨,经工业工艺处理后使之成为正极板,之后与常规的负极板构成小电池。对所得到的小电池进行了放电试验。同时,本文利用XRD、SEM、EDS等技术对添加不同量石墨的正极材料进行了表征。结果表明,向正极铅膏(约25 g铅粉)中添加0.5 g石墨的电池具有较高的放电容量。为解释不同石墨掺杂量对铅酸电池正极材料性能的影响机理,本文提出了铅板栅、石墨颗粒与铅膏颗粒的三种接触方式。
The different content of graphite was added into the positive paste of lead-acid battery used in industry. Then the positive plates made of graphite-doped paste after the industrial process were assembled with conventional negative plates to be small cells. The electrochemical performance of the simulated cells was thoroughly investigated. The prepared graphite-doped positive plates were characterized by XRD, SEM and EDS. The results indicated that the positive plates with 0.5 g graphite and 25 g lead oxidy had higher discharge capacity. Three contacting modes of lead grid, graphite particles and lead paste were proposed to interpret the obtained results.
