Sustainable technology experts developed a seawater-activated lithium battery. They needed entrepreneurial specialists to bring their business to market.

The next generation battery is here.


PolyPlus is a world leader in the development of next-generation battery technology. The Company invented and patented the protected lithium electrode (PLE) which is a core technology for lithium-sulfur, lithium-air, and lithium-water batteries.

PolyPlus has a world-class team of scientists and engineers and a rich pool of intellectual property totaling more than 135 issued and 40 pending patents. The PLE was recognized by TIME magazine as one of the 50 Best Inventions of 2011, and by the Edison Committee with a Gold Edison Award in 2012. Founded in 1991, they considered themselves a 25+ year old startup and were ready to step out of stealth mode.
