Company Background

Since our founding in 2000, Optodot has been developing advanced materials technologies to meet the pressing needs of the 21st century world market.  Optodot continually seeks to innovate in the commercialization of next generation products based on nanoporous membranes and nanocrystalline infrared (IR) organic coatings. Our discoveries in this field have produced a wide range of products for commercial, government, and military applications.

As the demand for electric vehicles (EVs) and high-energy electric grid storage accelerates, next-generation batteries must deliver increased performance at lower cost, all while satisfying stringent safety requirements.  The separator is arguably the most important component for achieving safety at the cell level.  As a result, battery separators have been upgraded to utilize a more heat stable metal oxide-based coating on the traditional plastic separators.  Optodot’s battery patents cover various metal oxide coatings with unique heat stability, porosity, and mechanical strength properties for separators to separate and insulate the positive and negative electrodes of lithium batteries from each other.

Dr. Steve Carlson, Optodot’s CEO, invented the use of hydrated aluminum oxide/boehmite separators in the mid-1990’s.  These separators are typically made using a sol gel coating that provides nanoporous separator membranes with a narrow and uniform pore size distribution centered at less than 100 nm. Hydrated aluminum oxide-based separators are now the preferred high performance battery separators for high energy density lithium batteries and today represent a $1.5 billion market that is growing at about 35% annually as the world converts to electric vehicles.  Optodot licensed its first generation of separator patents to three of the major lithium battery manufacturers.

Taking advantage of the functional hydroxyl groups on the hydrated aluminum oxide, the second IP generation covers the use of polymers, organic carbonates, organic sulfonic acids, and other materials reacted with the hydrated aluminum oxide to make superior grades of metal oxide-coated plastic separators, called ceramic-coated separators or “CCS” by the battery industry.  Optodot recently sold its patents for CCS to one of the top lithium battery manufacturers.

The second generation of separator patents also makes use of organic material treatments to enable a metal oxide separator, with no underlying plastic layer, that is strong and flexible, even though it is 45% to 50% porous, and thin (at a thickness of around 15 microns).  Optodot is the only company with a freestanding nanoporous separator of this type, called NPORE®, which features <1% shrinkage at very high temperatures and provides enhanced safety over CCS, all while reducing costs.

The third generation of Optodot’s separator patents covers the coating of the battery electrodes directly on the separator, which Optodot calls electrode-coated separators, or “ECS.”  Lithium batteries are currently made by coating the electrodes directly on a metal current collector foil, which is a costly and heavy material whose characteristics as a substrate are less than ideal for high-volume coating output.  ECS would reduce the capital and unit battery cost of lithium battery factories.  NanoPore® ECS provides a simpler process with fewer manufacturing steps and less factory labor, while retaining the key safety benefits of the NPORE® metal oxide separator with no plastic layer.

In addition to our research in the battery field, Optodot has also made important discoveries in the field of optical materials.  Our optical material patents, featuring unique properties in the infrared to prevent counterfeiting, have been used since 2009 in invisible security markings.  These optical materials have unique and intense absorption and reflectance properties that involve nanocrystalline organic materials and nanoscale coatings with a thickness of about 50 nm.
