Safer separators enabling current and next-generation lithium batteries

Meta Materials Expanding into Next-Generation Battery Materials to Enable Safer Transportation

Agreement to Acquire Assets and Extensive IP Portfolio of Optodot Corporation

HALIFAX, NS / ACCESSWIRE / June 17, 2022 / Meta Materials Inc. (the "Company" or "META®") (NASDAQ:MMAT, FSE:MMAT), a developer of high-performance functional materials and nanocomposites, today announced it has signed a definitive agreement to acquire substantially all of the assets and intellectual property, including 67 issued and 22 pending patents, of Optodot Corporation ("Optodot") for an aggregate of $48.5 million, comprised of $3.5 million in cash and $45 million of META shares of common stock. Optodot is a leading developer and licensor of nano-composite battery separators and infrared optical coating technologies, based in Devens, Massachusetts. The acquisition is expected to close in June, subject to customary closing conditions and regulatory approvals.

Optodot at the Forefront of Battery Development

On March 16, 2021, Optodot Corporation added a cutting‐edge U.S. patent to its portfolio of more than 90 pending and issued battery patents worldwide. This new IP is directed to Optodot’s NanoPore® Electrode Coated Separator (ECS) technology, defining an advanced design and manufacturing option for next‐generation batteries. With ECS, electrodes—for example, lithium metal anodes—are directly deposited onto the separator to form a separator/electrode stack.

Optodot Obtains New U.S. Patent for Advanced Battery Manufacturing Process

On March 22, 2022, Optodot Corporation was granted a new patent entitled “Methods of producing batteries utilizing anode metal depositions directly on nanoporous separators.”  U.S. Pat. No. 11,283,137, Dr. Carlson's 50th issued U.S. patent, is directed to lithium metal anodes (or any other anode active metal) deposited directly on any porous separator layer.  It is part of a family of patents that covers the deposition of electrode coatings directly on separators, a method which reduces not only manufacturing capital costs, but also unit and labor costs for lithium batteries.

Optodot Corporation Obtains New U.S. Patent for Battery Separators with Increased Thermal Conductivity

On January 4, 2022, Optodot Corporation was granted a new U.S. patent entitled “Nanoporous Composite Separators with Increased Thermal Conductivity.”  The patent, U.S. Patent No. 11,217,859, is directed to separators with greatly increased thermal conductivity compared to ceramic coated separators, which have a thermal insulating plastic layer.  Improved safety is crucial for the adoption of high energy-density lithium battery technology.  This is Optodot’s second U.S. patent in this family.
