Carbyne Polysulfide as a Novel Cathode Material for Rechargeable Magnesium Batteries

Abstract EN

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.
