Meta Supplies acquires property and IP of Optodot; battery separators and coating expertise


Meta Supplies Inc., a developer of high-performance practical supplies and nanocomposites, signed a definitive settlement to accumulate considerably all the property and mental property, together with 67 issued and 22 pending patents, of Optodot Company for an mixture of $48.5 million, comprising $3.5 million in money and $45 million of META shares of frequent inventory.

Optodot is a developer and licensor of nano-composite battery separators and infrared optical coating applied sciences, primarily based in Devens, Massachusetts. The acquisition is anticipated to shut in June, topic to customary closing circumstances and regulatory approvals.

META’s Superior Supplies and Battery Merchandise group will proceed joint improvement, licensing, and manufacturing scale-up of Optodot’s expertise in partnership with main OEMs. Optodot merchandise might be mixed and coated with META’s PLASMAfusion expertise, and META plans to develop capability at its facility in Thurso, Québec.


META will strengthen its proprietary portfolio of battery supplies with NPORE nano-composite ceramic separators to reinforce security, efficiency, and value in electrical automobiles. Further potential purposes for NANOPORE nanoporous membrane expertise embody ultrafiltration and medical metamaterial units.

The race to electrification and a brand new world during which electrical energy replaces gasoline and diesel is simply getting began. Shoppers need EVs with elevated vary and fast charging to get again on the highway rapidly. Batteries must be dependable and secure, whereas lowering price to drive wider adoption.

Optodot has developed disruptive, high-performance ceramic nanomaterials in partnership with main battery and medical tools OEMs. By means of this strategic acquisition, META expands its nanomaterials library and core experience to deal with key challenges in battery security and different purposes, opening multi-billion-dollar markets.

The worldwide marketplace for lithium-ion battery separators was an estimated $5.1 billion in 2021 and is projected to achieve $9.0 billion in 2025 (Supply: Yano Analysis Institute Ltd.). Separator shipments had been about 5.5 billion sq. meters in 2021 and are projected to achieve 15.9 billion sq. meters in 2025 (Supply: SNE Analysis). About 15 million m2 are required per GWh of battery capability (10-20 million m2, relying on the battery configuration).

Optodot licensed its 1st Technology boehmite ceramic battery patents to LG Chem in 2016; Optodot can also be a portfolio firm of LG Know-how Ventures. Optodot improvement initiatives have been funded by the US Division of Power and Protection Division, and it’s at the moment a subcontractor on a US Navy Section II SBIR venture led by Imperia Batteries, a division of Bodily Sciences Inc.

Optodot has collaborated with a spread of corporations, together with international automotive OEMs and main battery corporations. Improvement work can also be performed on the Roll-to-Roll Fabrication and Processing core facility on the College of Massachusetts Amherst. Within the area of infrared optical coatings, Optodot safety marking expertise is licensed by a worldwide medical tools producer to stop using counterfeit consumables.

Background. A battery separator—a porous membrane positioned between the electrodes of a battery—prevents contact between the anode and cathode whereas facilitating the transport of lithium ions. The problem in designing secure battery separators is to optimize porosity and ion transport, scale back the load and thickness of inactive supplies, whereas sustaining thermal and mechanical stability.

First technology separators are sometimes made by coating a plastic substrate on one or either side with ceramic materials. Second Technology NPORE nano-ceramic separators eradicate using plastic substrate and supply best-in-class dimensional stability with

In March 2021, Optodot was issued US Patent No. 10,950,837, titled “Strategies of Producing Batteries Utilizing Anode Steel Depositions Instantly on Nanoporous Separators.” Third Technology NPORE ECS Electrode Coated Separator expertise, developed with funding by the DOE, goals to scale back the price of manufacturing lithium-ion batteries and the inactive parts price by 20-40%, whereas enhancing battery security, lifetime, and power and energy density.


NPORE ECS incorporates new inactive parts of separator, present collectors, and termination supplies, and makes use of a less complicated and quicker battery meeting course of. With ECS, electrodes-for instance, lithium metallic anodes-are instantly deposited onto the separator to kind a separator/electrode stack.
