Safer separators enabling current and next-generation lithium ion batteries
WOBURN, Mass., 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.
