本研究以複合材料技術應用於全釩氧化還原液流電池(Vanadium Redox Flow Battery; VRFB)電池中金屬雙極板與金屬鋅空氣電池中鋅電極製程開發與其效能評估，未來這兩種電池在大型儲能方面有很大的應用潛力。由於具有導電性、抗蝕性、低成本等特性之複合碳材在電池的應用很廣。將VRFB電池雙極板由碳板改成金屬板，不但可大幅降低電池內阻，也提高電池的功率密度。使用金屬複合材料需要克服金屬腐蝕問題，本研究開發保護金屬雙極板表面的導電防蝕層，使用不同的碳材與黏結劑的漿料配比、製程條件、製程方式來改善導電防蝕層的塗佈特性、導電性、抗蝕性。複合碳材亦可應用在二次金屬鋅空氣電池中的鋅電極。二次鋅空氣電池的鋅電極在充電的過程中會有樹枝狀結晶導致電池的損壞。本研究藉由在鋅電極中添加不同比例的5~20%碳粉以改善此問題，並將結果利用模擬電池充放電來測試鋅電極的效能。

In this study, composite technology was applied to the development of metal bipolar plates for vanadium redox flow battery (VRFB) and zinc electrode for zinc-air battery. The performance these two batteries were also evaluated. These batteries had great potential for energy storage application. Composite carbon material has good electric conductivity, corrosion resistance, and low cost. They are widely used in batteries. Replacing the carbon bipolar plate of VRFB battery to a metal bipolar plate, not only greatly reduces the internal resistance of the battery, but also increases the power density of the battery. The use of metal composites needs to overcome the problem of metal corrosion. This study developed a conductive anti-corrosion layer for protecting the surface of metal bipolar plates. The paste ratio, process conditions, and process methods of different carbon materials and binders were studied to improve the coating of conductive anti-corrosion layer. The composite carbon material can also be applied to a zinc electrode a zinc-air battery. The zinc electrode may produce dendritic crystals during charging and cause damage to the battery. In this study, different proportions of 5-20% carbon powder was mixed with zinc powder to form the zinc electrode. These electrodes were tested by using simulated charging and discharging to evaluate the effectiveness of this zinc electrode.
