[0021] The present invention will be described in detail through the following examples:
[0022] The lead-carbon mixture proposed by the present invention is prepared by weight percentage of the following materials:
[0023] Carbon mixture: 20%~80%, lead powder: 20%~80%;
[0024] Wherein, the carbon mixture is prepared by weight percentage of the following materials:
[0025] Activated carbon: 10%~80%, conductive carbon material: 10~50%, bonding agent: 5%~50%, fiber: 0.1%~1%.
[0026] Activated carbon requires a specific surface area of 1000~3000m2 / g, preferably 1500~1800m2 / g. Conductive carbon materials include: acetylene black, Ketjen black, conductive graphite and other conductive carbon materials that can form a conductive network structure. The adhesive includes one of polyvinylidene tetrafluoroethylene (PVDF), polytetrafluoroethylene (PTFE) and styrene butadiene rubber (SBR); the fibers are short fibers or various conductive carbon fibers.
[0027] The carbon mixture accounts ...
