The invention discloses a lead paste formula for lead-carbon capacitor batteries rich in active material, which contains the following components measured by mass percentage: composite carbon material 1%-2%, lignin 0.1%-0.3%, polypropylene fiber 0.1%-0.3%, sulfuric acid 8%-10%, deionized water 11%-13%, and other multi-phase lead oxides. The composite carbon material is composed of humic acid 10%-15%, graphene 30%-35% and nano-carbon material 50%-60%. The invention also discloses a preparation method of negative lead paste rich in negative active material for lead-carbon capacitor batteries. The specific steps are as follows: first, preparation of composite carbon material slurry, then preparation of negative active material. The composite carbon material is reasonably added to the components of the battery, which greatly improves the conductivity, obviously improves the high power discharge performance and the high current charging performance. The battery made from the composite carbon material has the dual characteristics of battery and capacitor. In addition, the addition of composite carbon materials can also inhibit the growth of lead sulfate, so it can improve the cycle life of the battery.
