Meta Materials Reaches 500 Patent Milestone and Expands Portfolio of Granted US Lithium Battery Patents

HALIFAX, NS / ACCESSWIRE / March 15, 2023 / Meta Materials Inc. (the “Company” or “META®”) (NASDAQ:MMAT, FSE:MMAT), a developer of high-performance functional materials and nanocomposites, today announced an additional granted US patent directed to lithium batteries, using novel separators including but not limited to nanoporous ceramic NPORE® separators. META develops innovative materials to prevent battery fires, make batteries safer and more efficient, extend vehicle ranges and make battery supply chains more sustainable. META now has a total of 501 active patent documents, of which 315 patents have been issued.

This new patent, US Pat. No. 11,605,862, issued March 14, 2023, entitled Batteries Utilizing Anode Coatings Directly on Nanoporous Separators. It is aimed at lithium batteries where the anode or negative electrode comprises a dispersion or “wet” layer of anode materials. A second related patent from Meta Materials, US Serial No. 17/733,235, has received a Notice of Permission and will be issued shortly.

dr Steve Carlson, Executive Vice President, Advanced Materials and Battery Products at META, is the inventor. dr Carlson was named Inventor of the Year 2022 by the New York Intellectual Property Law Association (NYIPLA) for his inventions in the field of safer lithium batteries. This newly issued patent is his 54th US patent. META has a portfolio of more than 115 active patent documents worldwide related to lithium-ion battery technologies and battery and battery separator products.

“Battery fires are still a common problem in all applications, from mobile devices to e-bikes and electric vehicles. Both of our new products have features that help prevent thermal runaway,” said George Palikaras, President and CEO. “Due to the energy transition towards renewable grid sources and electric vehicles, the demand for copper is expected to increase dramatically. With solid copper foils accounting for approximately 10% of the weight of a typical battery cell, our NCORE™ product can significantly improve the efficiency and sustainability of batteries and electric vehicles.”

Next week, META will be presenting and exhibiting at the International Battery Seminar & Exhibit in Orlando, FL, March 20-23, 2023 at booth #917. META’s combined solution to improve battery safety and prevent thermal runaway at the cell level includes nanoporous NPORE® ceramic separators and NCORE™ metal-polymer current collectors. NPORE® separators are uniquely heat stable to prevent thermal runaway, with less than 1% shrinkage up to 220°C. NCORE™ eliminates up to 96% of copper or aluminum content, reduces battery weight by approximately 5%, frees up space for more activity material, and includes a fuse-like feature for increased safety.

“To protect our wide range of technology platforms, products and manufacturing technologies, META continues to expand its IP portfolio,” said Dr. Shann Kerner, META’s Chief Intellectual Property Officer. “We now have 501 active patent documents from 126 patent families, 68 of which contain at least one granted patent. This is an 86% increase compared to 269 active patent documents in 74 families a year ago.”
