Description |
In this work, we report an in situ generated carbon from sugar as additive in the Negative Active Mass
(NAM) which enhances the chargeedischarge characteristics of the lead-acid cells. In situ formed sugar
derived carbon (SDC) with leady oxide (LO) provides a conductive network and excellent protection
against NAM irreversible lead sulfation. The effect of SDC and carbon black (CB) added negative plates are
characterized by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM),
galvanostatic chargeedischarge, cyclic voltammetry (CV) and electrochemical impedance spectroscopy
(EIS), respectively. The results show that subtle changes in the addition of carbon to NAM led to subsequent
changes on the performance during partial-state-of-charge (PSoC) operations in lead-acid cells.
Furthermore, SDC added cells exhibit remarkable improvement in the rate capability, active material
utilization, cycle performance and charge acceptance compared to that of the conventional CB added
cells. The impact of SDC with LO at various synthesis conditions on the electrochemical performance of
the negative plate is studied systematically.
