1955 portfolio company Gridtential won the 2018 Sally Breidegam Miksiewicz Innovation Award for its silicon joule technology at this year’s BCI convention in Tucson, Arizona on April 30. The bipolar technology replaces the lead grids used as current collectors in traditional lead-acid monoblocs with silicon wafers. The associated boost in performance and reduced need for lead means that silicon joule enabled batteries can compete with lithium in emerging 48V automotive and other applications, the company says.
1955 portfolio company, Gridtential, an innovator in low-cost, high-performance energy storage technologies, announced today that it has appointed John Barton, former President of Global Asset Management for SunEdison, as Chief Executive Officer of Gridtential. The company also announced that Bob Gruenstern, former Johnson Controls Global Vice President for Product and Advanced Engineering, joined its Technical Advisory Board. Both Barton and Gruenstern bring decades of critical operations and product development expertise as Gridtential accelerates plans for the commercialization of its patented Silicon Joule® battery technology.
Venture capital investors once again are getting charged up over new battery technologies…. One of the latest to raise new money is Gridtential, a battery technology developer pitching a new take on a classic battery chemistry… the centuries old lead acid battery. Gridtential’s innovation, for which it’s filed several patents, is to use silicon plating instead of non-reactive lead plating in the battery.
The company’s novel approach has won it the backing of four big battery manufacturers, in an earlier $6 million round of funding in January, and now the company has raised another $5 million to continue to build out the business from new investor 1955 Capital.
