Optodot Corporation Awarded START Funding

July 25, 2017

Optodot Corporation has been awarded START funding for its NPORE® heat-resistant separator for lithium ion batteries. The NPORE® separator is a flexible, all-ceramic, nanoporous membrane that improves the safety of lithium ion batteries because it does not shrink or melt until temperatures reach well above 220ºC. Optodot is a product development company that commercializes technologies primarily through licensing and strategic partnerships. “The START program funding will support Optodot’s transition from technology development to customer qualification and sales. We are honored to receive this competitive award which will help propel the next stage of growth for our company.” – Steve Carlson, Founder and CEO, Optodot

Optodot Corporation Awarded SBIR Phase II Enhancement Contract

June 6, 2016

Optodot Corporation is pleased to announce that it has received a continuation award under its Small Business Innovation Research (SBIR) Phase II contract by the U.S. Army to develop the world’s first all-ceramic separator for lithium ion batteries. During Phase II, Optodot successfully scaled up its heat resistant ceramic separator on large-scale production equipment. The all-ceramic separators, trademarked NPORE®, eliminate the need for the polyolefin support layer, offering an unparalleled combination of higher heat resistance and thinner ceramic separators for safer, higher energy density lithium ion batteries. Optodot will continue its work under the Phase II Enhancement contract, with a focus on developing its advanced ceramic separators for new large lithium ion battery applications. Development of heat-resistant separators is critical to the safety of lithium ion batteries for vehicles and other large format applications.
