Seeo, a developer of advanced lithium polymer batteries, has closed what it says as the company's largest funding round to date, and added Samsung Ventures Investment Corp. as an investor. The invested capital will run the commercialisation of California-based Seeo's ultra-high energy density advanced lithium polymer batteries, the company revealed.

Earlier investors Khosla Ventures and GSR Ventures also participated in the financing round.

"We appreciate the confidence Samsung Ventures has expressed in our technology and team with this investment," said Hal Zarem, president and CEO of Seeo. "Samsung Ventures is a sophisticated investor with deep experience and a track-record of success in the space. Their engagement with Seeo will strengthen our ability to deliver the next generation of advanced batteries to a market eager for breakthrough capabilities."

Seeo's DryLyte electrolyte enables breakthroughs in energy density, which is a key enabler to increasing the range of electric vehicles (EVs). As of the present, Seeo has cells cycling with an energy density of 350Wh/kg, with a future target of 400Wh/kg, roughly twice the level of batteries used in today's EVs.

Seeo enables the production of safer batteries by replacing the flammable liquid electrolytes of conventional lithium-ion cells with Seeo's DryLyte solid polymer electrolyte that is non-flammable and non-volatile. These enhanced safety characteristics, combined with exceptionally high energy density, represent a breakthrough for next-generation battery applications.
