Sulfur nanodots on nickel foam as high-performance Li-S cathode materials; carbon- and binder-free
Green Car Congress
JANUARY 3, 2015
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. mg/cm 2 S on the Ni foam exhibited high initial discharge capacity (1458 mAh/g at 0.1
