Printing Nanoporous Ultrathin Membranes for Lithium-Sulfur Batteries
RPI ID:
2019-021-401
Innovation Summary:
This technology provides a graphene oxide (GO) printed coating for separator membranes in lithium-sulfur (Li–S) batteries. The printed GO layers block polysulfide migration, addressing the ‘shuttle effect’ that reduces Coulombic efficiency and cycle life. Unlike traditional coatings,...
