PolyPlus Battery Company

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.

Solid-state electrolytes and the quest for a safer battery

2016 was the year of Li-ion batteries' silver jubilee, a coming of age that has not been hassle-free, as Samsung's Firegate showed us. This year might mark the first significant switch to new materials in the electrolyte compartment, with both large and small companies trying to bring inorganic and polymer electrolytes to commercial fruition.

Traction batteries beyond Li-ion arriving early

Lithium-ion batteries involve lithium ions being intercalated and de-intercalated at electrodes during cycling. Other batteries involve lithium ions but are not called lithium-ion because they work in another way. There are single use versions but now there are rechargeable versions arriving earlier than most pundits thought possible.
