A team at Nankai University in China has devised high-performance Li-sulfur battery cathode materials consisting of sulfur nanodots (2 nm average) directly electrodeposited on flexible nickel foam; the cathode materials incorporate no carbon or binder. However, the electrochemical inertness of bulk sulfur in the cathode of Li?
