This work reports the first demonstration of bismuth oxyhalides as anode materials in potassium-ion batteries. BiOCl nanoflake assemblies deliver high capacities of 367 mA h g-1 at 50 mA g-1 and 175 mA h g-1 at 1 A g-1. The formation of K-Bi alloys at an early stage of potassiation is observed.
这项工作报道了首次证明卤氧化铋作为钾离子电池负极材料的研究。BiOCl纳米片组装体在50 mA g-1电流密度下展现出367 mA h g-1的高容量，在1 A g-1电流密度下容量为175 mA h g-1。在钾化早期观察到了K-Bi合金的形成。
