鋰空氣電池因為使用鋰金屬做為電池陽極，並自空氣中擷取氧氣作為電池陰極，因此大幅減少電池本身載重，提升單位重量能量密度，擁有高達3860 mAhg-1的理論電容量，是目前最接近石油能量密度的替代性能源載體，在面臨能源危機的當下，有潛力成為新興的替代性能源載體。
鋰空氣電池的陰極為氧氣，在其他電池中原本應為陰極的位置，取而代之的是可催化充放電反應的多孔空氣電極，多使用可有效降低反應活化能的材料製作，以提升鋰空氣電池的電性表現，除此之外空氣電極的孔隙分佈會影響氣體可反應的有效面積，進而影響催化劑的利用效率決定最後電性表現的優劣。
本研究中使用Graphene做為空氣電極基材，探討電極的製作過程中調變黏著劑 (binder)比例是否會影響空氣電極的孔隙率，並在Graphene基材中接合白金粒子，比較接合前後的電性表現判斷白金是否可以有效降低充放電反應的活化能，藉以控制鋰空氣電池的電性表現。
