Carbon additives in negative active material (NAM) electrodes enhances the cycle life of the Lead Acid (LA) batteries. Hydrogen evolution reactioncaused by carbon additives can be controlled with lead-carbon composites or metal/metal-oxides.
In the case of valve-regulated lead-acid batteries (VRLA), carbon can be oxidized by oxygen transported from positive plates, which prevents recombination of this gas with hydrogen and increases the loss of water and additionally lowers the beneficial effect of this additive on the charge acceptance .
The inherently poor dynamic charge-acceptance of the lead–acid battery can be greatly improved by the incorporation of additional carbon to the negative plate. An analysis is undertaken of the various ways by which the carbon may be introduced, and of the proposed mechanisms whereby its presence proves to be beneficial.
Replacement of heavy lead grids with carbon collectors reduces the weight of batteries resulting in the increased specific energy of the battery. There is a major difference between the theoretical specific energy of the lead-acid battery, which equals 168 Wh kg −1, and typically acquired results in the 30–40 Wh kg −1 range.
