Conventional Li–S batteries have a non-compact cathode structure containing low areal loading of active materials. Now, a strategy of burning Li foils in a CS2 vapour is presented, which leads to the formation of highly compact Li2Snanoparticles as a lithiated sulfur cathode, oﬀering promising battery performance.
