Grafoid logoGrafoid, the Canadian graphene R&D, investment and technology company, announced the development of its GPURE Graphene Polymer nano-porous membrane intended for next generation Li-Ion battery applications.

The GPURE graphene polymer membrane (GPM) was developed as a chemically inert, freestanding membrane using graphene composites to test ion selectivity using both monovalent and divalent ions. Ion selectivity is a key requirement for a semi permeable membrane in a Li-ion battery structure. By protecting the sensitive electrode materials from unwanted chemical species GPURE GPM diffuses only energy harvesting monovalent ions such as Li+, Na+ etc.

In February 2017, Grafoid unveiled its family of GPURE Platform membrane technologies spanning a range of scalable industrial applications requiring novel, disruptive solutions to create new products or enhance or supplant existing membrane technologies.
