We report the formation of carbyne polysulfide by coheating carbon containing carbyne moieties and elemental sulfur. The product is proved to have a sp2 hybrid carbon skeleton with polysulfide attached on it. The electrochemical performance of carbyne polysulfide as a novel cathode material for rechargeable magnesium batteries is firstly investigated. The material exhibits a high discharge capacity of 327.7 mAh g(-1) at 3.9 mA g(-1). These studies show that carbyne polysulfide is a promising candidate as cathode material for rechargeable Mg batteries if the capacity retention can be significantly improved.
我们报道了通过共热含卡宾部分的碳和元素硫形成聚硫化碳炔。该产物被证明具有一个sp2杂化的碳骨架，上面附着有聚硫化物。首次研究了聚硫化碳炔作为可充电镁电池新型阴极材料的电化学性能。该材料在3.9 mA g(-1)时表现出327.7 mAh g(-1)的高放电容量。这些研究表明，如果能够显著提高容量保持率，聚硫化碳炔是一种有前景的可充电镁电池阴极材料候选物。
