Dense graphene papers: Toward stable and recoverable Al-ion battery cathodes with high volumetric and areal energy and power density

For addressing the challenges of balancing the rapid ion transport channels and volumetric/areal energy storage capability at a dense fashion, here an exceptional conductive graphene papers that are well stacked by conductive graphene nanosheets have been demonstrated as an electrochemically stable host for stable Al-ion battery cathodes with high volumetric and areal energy and power density.248
