摘要：
In their recent publication in Nature, Kang Xu, Chunsheng Wang, and co-authors reported for the first time on a novel halogen conversion-intercalation graphite cathode chemistry for the development of high-energy aqueous batteries. As evidenced by experimental works and modeling, a densely packed stage-1 graphite intercalation compound (GIC) with a stoichiometry of C-3.(5)[Br0.5Cl0.5] is reversibly formed in a water-in-bisalt (WiBS) electrolyte, enabling an outstandingly high specific cathode capacity of 243 mAh g(-1) at an average potential of 4.2 V versus Li/ Li+.
