Lead-acid batteries are the oldest and most widely used rechargeable batteries, known for their reliability and low cost. They operate on a reversible chemical reaction between lead dioxide (PbO2) and sponge lead (Pb) electrodes immersed in a sulfuric acid (H2SO4) electrolyte. Despite their lower energy density compared to newer technologies, lead-acid batteries remain crucial for automotive, backup power, and stationary applications.

Addition of Cancrie’s carbon in lead acid batteries as an expander material results in improved electrode surface area and overall active material cohesion strength increases 3X. Due to our carbon’s interconnected pores, the electrochemical reactions significantly improves resulting in upto 96-98% Ampere hour efficiency and higher capacities at faster discharge rates. It also offers benefits like faster charging with high current rates of up to 0.2C as it lowers the ESR of electrode. It also impedes the build up of hard sulfation crystals, thereby increasing the lifecycle of the battery by more than 50%, which is by far the most sought out benefit for a highly competitive lead acid battery industry.
