提出了一种新的无缺陷原则来设计铝离子电池石墨烯阴极：缺陷越少，性能越好。通过可扩展的方法开发的无缺陷石墨烯气凝胶阴极在500 C的倍率下提供100 mAh g（-1）的高容量，超过了有缺陷的石墨烯和先前的报道。这种无缺陷的原则可以指导我们制造更好的石墨烯基电极。
A conceptually new defect-free principle is proposed for designing graphene cathode of aluminum-ion battery: the fewer the defects, the better the performances. Developed through scalable approach, defect-free graphene aerogel cathode affords high capacity of 100 mAh g(-1) under an ultrahigh rate of 500 C, exceeding defective graphene and previous reports. This defect-free principle can guide us to fabricate better graphenebased electrodes.
