High performance battery applications call for thermally and chemically most stable separator membranes. Novamem is proud to be the first supplier worldwide to provide nano- to microporous pure PEEK membranes (no chemical modification such as sulfonation). Our PEEK membranes have a yet unbeaten porosity, which is combined with all advantageous material properties of pure PEEK. Their very thin structure (in the range of a few microns) allows very rapid transport characteristics. Our unique and patented technology furthermore allows us to tune pore sizes in a very broad range (nanometers to micrometers) depending on your specific needs. This makes Novamem PEEK membranes ideal for your battery separators.
