Optodot and LG Chem Sign Li-ion Patent LicenseApril 25, 2016 by Jeff Shepard
Optodot Corporation recently granted a license to LG Chem Ltd. under a patent portfolio controlled by Optodot covering batteries, cells, separators and electrolyte members comprising boehmite. Boehmite is a key material used in what the battery industry calls "ceramic" coating layers.
â€œWe are pleased that LG has shown a strong interest in the boehmite technology,â€ said Dr. Steven A. Carlson, president and CEO of Optodot. â€œBoehmite ceramic coating layers offer a number of distinct benefits in lithium ion batteries, including improved thermal stability to enhance the safety of lithium ion batteries.â€
The patent portfolio includes 20 patents issued in the U.S., Japan, Korea, China, and Europe. The license permits LG Chem, the largest Korean chemical company and a leading battery manufacturer headquartered in Seoul, Korea, to utilize boehmite separator films for lithium-ion batteries.
Optodot Corporation is an intellectual property, product development, and contract services company specializing in a wide variety of products, including lithium ion batteries and separators. In addition to developing its own boehmite ceramic coating, Optodot is developing next-generation all-ceramic boehmite separators that are being evaluated by several leading lithium ion battery manufacturers.
The all-ceramic separators, trademarked NPOREÂ®, eliminate the need for the polyolefin support layer, offering an unparalleled combination of higher heat resistance and thinner ceramic separators for safer, higher energy density lithium ion batteries.
