Abstract

Disclosed herein is a composition for use in a negative active material in a valve regulated lead-acid battery, including a carbon material having a BET surface area from 150 m2/g to 2000 m2/g and having a D90-value greater than 5 μm with the amount of carbon material ranging from 0.1 wt % to 1.5 wt % based on the total weight of the composition. Also disclosed herein is a valve regulated lead-acid battery, including a positive plate, a negative plate, a separator, and an electrolyte disposed in a container with a valve, the negative plate including a substrate of lead or a lead alloy and a negative active material of a composition including a carbon material having a BET surface area from 150 m2/g to 2000 m2/g and having a D90-value greater than 5 μm, the amount of carbon material ranging from 0.1 wt % to 1.5 wt % based on the total weight of the composition.
