PolyPlus Battery Company

Profile
PolyPlus started operations in Berkeley, California in 1991 based upon inventions made by two scientists at Lawrence Berkeley National Laboratory and since then the Company has built one of the strongest battery development teams in the world resulting in breakthroughs in Lithium-Sulfur, Lithium-Air, and Lithium-Water batteries. PolyPlus has made a major breakthrough in the invention of protected lithium metal electrodes (PLEs). The result is the development of battery chemistries with unprecedented energy density, including rechargeable and non-rechargeable Lithium-Air and Lithium-Water batteries. The Company has recently demonstrated Li-Water batteries that have delivered 1300 Wh/kg, the highest specific energy ever measured for any battery chemistry.
