Carbon-supported SnS composite was prepared via a solvothermal process followed by thermal calcination. The carbon nanosheets could not only ensure electron conduction within the composite but also alleviate the volume change of SnS during the charging/discharging process. As a result, when employed as an anode material for potassium-ion batteries, the composite delivers good potassium storage performance. In detail, at a current density of 100 mA g−1, its capacity is still higher than 102.6 mAh g−1 after 50 cycles. In terms of long-cycling stability, 76.1 mAh g−1 was obtained after 200 cycles at 200 mA g−1.

钾离子电池用碳载硫化锡阳极
碳负载的SnS复合材料是通过溶剂热法,然后进行热煅烧制备的。碳纳米片不仅可以确保复合物中的电子传导,还可以减轻充电/放电过程中SnS的体积变化。结果,当用作钾离子电池的负极材料时,该复合材料具有良好的钾储存性能。详细地,在100mA g -1的电流密度下,其容量在50个循环之后仍高于102.6 mAh g -1。在长期循环稳定性方面,76.1毫安克-1是200次循环后以200mA克得到-1。
