将经过化学处理的多壁碳纳米管添加到铅酸电池的阳极材料中,将其制作成电极并测试了不同充放电流条件下的循环特性,研究了碳纳米管对容量、循环寿命和活性的影响.X射线衍射分析证实在阳极板中形成了PbO2,在阳极板中添加多壁碳纳米管能够提高活性物质的利用率,还能有效抑制效率的降低.
Chemical modified multiwalled carbon nanotubes(MWCNTs) were added into the positive mass of the lead-acid battery.The powder microelectrode was manufactured and the cycling performance was studied using different charge-discharge current. The influence of carbon nanotube additives to the capacity, cycle longevity and activity were investigated. X-ray diffraction studies reveal that the formed plates position is PbO2 in the positive electrodes. The plates with MWCNT additive exhibit a higher utilization of the positive active material.The decline of the efficiency can be restrained effectively.
