Abstract

Here we report a tunable three-dimensional (3D) macroporous carbon nanotube (CNT) foam as a sulfur cathode for lithium sulfur batteries. Stable electrochemical performance was achieved with high initial capacity and decent cycleability. Next, based on the materials, sets of Li-S cells were tested under designed scenarios to demonstrate the effect of lithium polysulfide (LiPS) solubility on cell capacity. It reveales that when LiPS solubility limit is reached, though sulfur can be reduced to solid state LiPS, it cannot further convert to subsequent discharge products and contribute to cell capacity.
