New lithium polysulfide flow battery for large-scale energy storage

Green Car Congress

Researchers from the US Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a new lithium/polysulfide (Li/PS) semi-liquid (flow) battery for large-scale energy storage, with lithium polysulfide (Li 2 S 8 ) in ether solvent as a catholyte and metallic lithium as an anode.

The Net-Zero Neighborhood: Advanced Energy Storage and Highly Efficient Photovoltaics Take Transportation Off the Gasoline Grid and Residential Off the Electric Grid

Green Car Congress

Gil Weigand of Oak Ridge National Laboratory outlined his vision of a critical solution to the energy, climate and ensuing national security threats facing the US: the Net-Zero Neighborhood (NZN). If we are going to create some of the batteries, you better be ready to crank out some cycles.” This is not a small engineering feat.
