Example Embodiment

[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 ...

Abstract

The invention discloses a lead and carbon mixture for manufacturing a lead-acid battery electrode plate. The lead and carbon mixture is prepared from the following materials by weight percentage: 20-80 percent of carbon mixture and 20-80 percent of lead power, wherein the carbon mixture is prepared from the following materials by weight percentage: 10-80 percent of activated carbon, 10-50 percent of conductive carbon material, 5-50 percent of adhesive and 0.1-1 percent of fiber. The invention discloses a method for manufacturing the lead-acid battery electrode plate with the lead and carbon mixture. The bonding strength of a coating and the surface of the electrode plate is high, the effect of a hydrogen evolution inhibitor is good, and the coating can be coated onto the surface of a grid and can also be coated onto the surface of the electrode plate. The method is more flexible than the traditional process for manufacturing lead-acid batteries.

Description

technical field [0001] The invention relates to the field of lead-carbon batteries, in particular to a lead-carbon mixture used for lead-acid battery pole plates and a method for manufacturing lead-acid battery pole plates by using the lead-carbon mixture. Background technique [0002] Australia's Commonwealth Scientific and Industrial Research Institute (CSIRO) and Japan's Furukawa Battery Co., Ltd. have made great progress in the field of lead-carbon batteries, and have applied for related patents in various countries. These patents mainly relate to how to combine activated carbon with the active material of the negative plate well. [0003] Furukawa mentioned in EP2424011 and CN102484245A that the negative electrode plate coated with activated carbon coating was immersed in a 1.30g / L sulfuric acid solution in which octadecanoate and aluminum sulfate were dissolved. Part of the lead ions, during the charging process before formation, the lead ions in the micropores are re...
