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.
