A hollow carbon substrate is prepared via a simple hydrothermal method with sulfonated polystyrene sphere as the template. A sulfur-carbon composite based on the carbon substrate shows a high electrochemical activity, an ultralong lifespan (255 days, 600 cycles), and a favorable rate capability in a Li-S battery.
