不同炭材料的掺杂对铅酸电池正极板性能的影响

摘要

Graphite, carbon nanotubes and graphene with same content were respectively doped into the positive lead paste for lead-acid battery. After the discharging tests, the prepared carbon-doped positive plates were characterized by XRD, SEM and EDS. The results showed that the graphite-doped sample had more discharge capacity and better corrosion resistance in comparison to other samples.%在铅酸蓄电池正极板的铅膏中分别添加质量分数相同的石墨、碳纳米管和石墨烯,经过和膏、干燥等步骤制备成不同炭材料掺杂的正极板.在进行放电测试后,利用 XRD、SEM、EDS等分析方法对三种正极板材料进行了表征.结果表明,向正极铅膏中添加石墨的电池具有较高的放电容量,较好的抗腐蚀性.
