Abstract
The invention discloses a method for preparing negative-pole lead plaster for a lead-carbon storage battery. The method comprises the following steps of: dissolving lead acetate into ethylene glycol, taking resorcinol and furfural as reacting monomers, carrying out closed reaction after a cross-linking agent is added, drying to obtain organic aerogel containing lead, and carrying out high-temperature carbonization, thereby obtaining the aerogel containing lead and carbon; preparing raw materials for the negative-pole lead plaster; and mixing the raw materials and carrying out plaster mixing. According to the negative-pole lead plaster for the lead-carbon storage battery, prepared by the method, the aerogel containing lead and carbon is adopted as a main ingredient for the negative-pole lead plaster for the lead-carbon storage battery, and a specific material proportioning ratio is adopted, so that the negative-pole lead plaster is higher in active material utilization ratio in the case that poor electrochemical performance caused by unsatisfactory physical lead-carbon mixing and short battery cycle life due to the fact that the negative-pole lead plaster easily falls off are changed; and when the negative-pole lead plaster is applied to the lead-carbon storage battery, the lead-carbon storage battery has the advantages of high specific capacity, ultra-stable cycle performance and long service life.
