Effect of propanetriol on the electrochemical behavior of nano fumed silica gel

摘要：

The effect of propanetriol on the electrochemical properties of nano fumed silica gel of Valveregulated lead-acid (VRLA) batteries have been investigated by means of cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), transmission electron microscope (TEM) and linear sweep voltammetry (LSV). The results show that with the adding of propanetriol the redox peak current density of the lead electrode greatly increases and the reaction resistance reduces obviously. Additionally, the oxygen reactions take place less easily in the gels containing propanetriol. The content of the additive propanetriol also relates with the gel properties. It is proved that the electrochemical properties of gel contained excessive propanetriol (4wt％) are not as good as that contain 1wt.％～3wt.％.
