摘 要：Natural graphite is investigated as the cathode for aluminum ion batteries in recent years. However,some drawbacks of the natural graphite such as severe volume swelling shorten its lifetime. In this work, we prepared a composite material by depositing an amorphous carbon on the graphite paper. The composite was used as a cathode to study the electrochemical performance in aluminum ion batteries.The charge/discharge results showed that the composite could exhibit a longer cycle life than the graphite paper. Electrochemical analyses demonstrated that the interface between the amorphous carbon and the graphite paper made a major contribution to the improvement of the cycling stability.
