摘要

二次鋁離子電池主要是以鋁金屬當作負極、石墨當作正極以及使用離子液體作為電解液。鋁離子電池具有低成本、不可燃性、高速率充放電、長圈數的壽命以及牽涉三個電子的氧化還原反應等特點。本文將介紹不同正極碳材料用於鋁離子電池之效能表現，進而利用X光電子能譜及拉曼光譜分析石墨材之陰離子插層機制，同時也將簡介不同碳材近期用於高效能鋁離子電池之發展。

A rechargeable Al ion battery (AIB) has been developed and composed of Al metal foil as anode electrode, graphite materials as cathode electrode and ionic liquid as the electrolyte. Owing to its low cost, rapid charging/discharging, excellent cyclability, high-rate capability, and inflammability, AIB provides a safe alternative to many commercial batteries used in the energy storage system. In this paper, the performances of different materials used as cathode electrode in Al ion battery will be introduced. The mechanism of chloroaluminate anion (AlCl_4^-) intercalated in the graphite layer studied via X-ray photoemission spectroscopy, X-ray diffraction and Raman spectroscopy will be discussed. Recent developments of active graphite materials for rechargeable AIB's performance improvement will be reviewed as well.
