摘要

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.
