Sodium-sulfur batteries operating at ambient temperature are being extensively studied because of the high theoretical capacity and abundant resources, yet the long-chain polysulfides’ shuttle effect causes poor cycling performance of Na–S batteries. We report an annealing/etching method to converse...
