In the race to improve lead–acid battery performance for demanding applications that require high dynamic charge-acceptance (DCA), advanced carbon additives have emerged as the key to achieving good performance. Significant work has been undertaken to demonstrate that carbon additives enhance DCA in these areas, yet minimal effort has been directed towards determining how the properties and processing of carbon in a paste affect overall performance. Carbons vary substantially in physical properties (e.g., surface area, surface chemistry, density), and also in paste processing characteristics (e.g., hydrophilicity, uniform distribution in a paste). Understanding how to process carbons effectively in a lead–acid paste is imperative to achieving optimum performance. Specialty carbons, specifically synthetic, ultrapure materials with highly-designed porosity created by EnerG2, can require different processing from other types of carbon. This presentation will outline differences in the way carbons are processed in lead-acid pastes, and how this processing affects key physical and electrochemical features in the paste, plate, and battery.
