習知應用於超級電容的石墨烯／聚苯胺（Graphene Polyaniline Composite, GPC）複合材料具快速充、放電的特性，其成本較純奈米碳管及石墨烯低且因分散性佳易於製程中操作，因此本研究應用該複合材料作為快充鋰電池的應用上。研究中設計不同含量的複合材料加入正、負極中，進行多組實驗找出最佳的條件。結果發現添加0.5 % GPC於正極中，電池的3C定電流充電效率可由原先的60%提升到80%，且具有最佳的老化、放電與循環性能表現。然而當加入1% GPC時，便存在自放電的問題，另一方面，將GPC添加於負極極片時，因電池阻抗高導致整體電性性能下降。

Graphene/polyaniline composite (GPC) with fast charging/discharging characteristics are commonly used in supercapacitors. The cost of GPC is lower than that of pure carbon nanotubes and graphene. In this study, we thoroughly examined the application of these composite materials in fast-charging lithium batteries, including cycle life and C-rate tests. In the research, composite materials with different contents were designed to be added to the cathode and anode electrodes, and several sets of experiments were carried out to find the best conditions. The results showed that the batteries adding 0.5 % GPC in the cathode electrode could improve 3C constant current charging efficiency from the original 60 % to 80 %. In addition, those batteries had the best aging, discharge and cycle performance. However, when 1 % GPC was added, self-discharge issue was found. On the other hand, the performance of batteries was deteriorated due to the higher resistance if added GPC in the anode electrode.
