Aluminum-ion batteries (AIBs) are emerging as an attractive new electrical energy storage system. Despite the recent breakthroughs in AIB technology, state-of-the-art cathode materials suffer from mediocre volumetric capacity (∼0.74 mA h cm−3) and AIBs in the widely used coin-cell configuration are rarely reported. Here, we present the synthesis of free-standing monolithic nanoporous graphene foam with a high density and a new strategy to stabilize coin-cell type AIBs. Our designed coin-cell AIBs demonstrate a volumetric capacity up to 12.2 mA h cm−3, a gravimetric capacity of 151 mA h g−1 and good low temperature performance.

独立式整体式纳米多孔石墨烯泡沫作为高性能铝离子电池阴极

铝离子电池(AIB)逐渐成为一种有吸引力的新型电能存储系统。尽管最近在AIB技术上取得了突破,但最先进的阴极材料的平均容量(平均约为0.74 mA h cm -3)仍然受苦,很少有人报道采用广泛使用的纽扣电池配置的AIB。在这里,我们介绍了具有高密度的独立式整体纳米多孔石墨烯泡沫的合成以及稳定纽扣电池型AIB的新策略。我们设计的纽扣电池AIB的体积容量高达12.2 mA h cm -3,重量容量为151 mA hg -1,并且具有良好的低温性能。
