| Description |
The discharge performance of lead-acid battery is improved by adding multi-walled carbon nanotubes (MWCNTs) as an alternate
conductive additive in Negative Active Mass (NAM).We report thatMWCNTs added to the negative electrode, exhibits high capacity,
excellent cycling performances at 10-h rate, high rate partial state of charge (HRPSoC) cycling and various rates of discharge. It
significantly reduces the irreversible lead sulfate on the NAM, increases the active material utilization and improves the electrode
performance. The improvement of capacity and cyclic performance of the cell is attributed to the nanoscale dimension of the
MWCNTs as additive. Subsequent characterization using high resolution transmission electron microscopy and scanning electron
microscopy were carried out to understand the influence of MWCNTs on the negative electrode of lead-acid battery.
