Abstract
Due to the quick leap on battery technology in recent years, the application of lithium-ion battery is expanding very fast. However, related researches mostly focus on surface modification of graphite anode materials. By contrast, subjects about conductive additives are relatively rare. This research investigated the adding carbon nanotubes (CNTs) on natural graphite anode materials. Due to the poor dispersing effect of CNTs, PVA was utilized as the dispersant in the process. After coating the natural graphite with PVA, modification was carried on by adding CNTs in different ratio in order to increase the electrochemical properties as well as raise rate and cycle performance of the battery. The results show that the coating natural graphite with 3 wt% PVC and then adding 2 wt% CNTs as conductive additive could achieve 361.0 mAh/g in discharge capacity. Moreover, rate and cycle performance were greatly improved at the same time.
