Lithium–sulfur (Li-S) battery


The lithium–sulfur battery (Li–S battery) is a rechargeable battery, notable for its high energy density. By virtue of the low atomic weight of lithium and moderate weight of sulfur, Li–S batteries are relatively light; about the density of water. They were demonstrated on the longest and highest-altitude solar-powered airplane flight in August, 2008.

Applications: short-term storage, arbitrage, distributed/off-grid storage, mobility
