Fluoride is a promising charge carrier for batteries due to its high charge/mass ratio and small radius. Here, we report commercial copper powder exhibits a reversible capacity of up to 222 mA h g in a saturated electrolyte of 16 KF. This electrolyte suppresses dissolution of CuF, the charged product. Furthermore, the KF solid comprised in the Cu electrode facilitates a high initial capacity. Our results showcase the potential of aqueous fluoride batteries using copper as an electrode.
由于氟化物具有高电荷/质量比和小半径，它是一种很有前景的电池电荷载体。在此，我们报道在16KF的饱和电解质中，商用铜粉展现出高达222 mA h g的可逆容量。这种电解质抑制了带电产物CuF的溶解。此外，铜电极中包含的KF固体有助于实现高初始容量。我们的结果展示了使用铜作为电极的水性氟化物电池的潜力。
