An ultrahigh‐loading lithium polysulfide cathode is developed to investigate the electrochemical behaviors of high‐energy Li‐S batteries. With this design, Li‐S batteries with an ultrahigh areal sulfur loading (18.1 mg cm –2 ) are achieved with low polarization, high areal capacity, and promising cycling performance. It is further demonstrated that the challenge for high sulfur loading cells is the serious lithium‐metal corrosion and electrolyte depletion.
