Fabrication of PbSO(4)negative electrode of lead-acid battery with high performance

摘要

This paper reports the preparation and electrochemical properties of the PbSO(4)negative electrode with polyvinyl alcohol (PVA) and sodium polystyrene sulfonate (PSS) as the binders. The results show that the mixture of PVA and PSS added to the PbSO(4)electrode can significantly improve the specific discharge capacity of the PbSO(4)electrode, which reaches 110 mAh g(-1)and survives 700 cycles at full charge and discharge at 100 mA g(-1). The mixture of PVA and PSS can also replace the short fibers used in conventional cells, and shortens the activation time of the electrode.
