Graphene oxide-sulfur (GO-S) nanocomposite cathodes for high-capacity, stable cycling lithium sulfur batteries

Green Car Congress

A team from Lawrence Berkeley National Laboratory and Tsinghua University (China) have synthesized graphene oxide-sulfur (GO-S) nanocomposite cathodes and applied them in lithium/sulfur cells to show a high reversible capacity of 950-1400 mAh g -1 and stable cycling for more than 50 deep cycles at 0.1C (1C = 1675 mA g -1 ).

China team uses LiPON coating to protect Li metal anode in Li-S batteries

Green Car Congress

A team of researchers in China has devised a simple and mass-produceable method to modify a Li metal anode to avoid the formation of an unstable solid electrolyte interphase (SEI) and the subsequent growth of Li dendrites in high-energy-density Li-S batteries. A paper on their work is published in the journal Energy Storage Materials.
