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 ).

Purdue engineers use upcycled plastic to boost performance and lifespan of Li-S batteries

Green Car Congress

Purdue engineers have used upcycled low-density polyethylene (LDPE) plastic to boost the lifespan of lithium-sulfur batteries. When a PSC layer was utilized as an interlayer in lithiumsulfur batteries, the sulfur cathode delivered an improved capacity of 776 mAh g –1 at 0.5C Kim, Harif D. 8b03959.
