Carbon blacks for lead-acid batteries in micro-hybrid applications - Studied by transmission electron microscopy and Raman spectroscopy

► Lead-acid starter batteries with different carbon blacks in the negative active material were cycled in typical PSoC tests. ► Batteries with highly ordered carbon blacks in the NAM showed superior cycle life in the 17.5% DOD test. ► Electrical data have been complemented by SEM, TEM and Raman investigations.
