LG Chem Licensing Li-Ion Battery Tech From Optodot
Originally published on EV Obsession.
Optodot Corporation and LG Chem have signed a new patent license agreement that will see the lithium-ion battery manufacturer granted the right to utilize the boehmite separators developed by Optodot, according to a new press release.
To provide some background here, boehmite is a material utilized in the “ceramic” coating layers of many modern battery designs.
“We are pleased that LG has shown a strong interest in the boehmite technology,” stated Dr Steven A Carlson, president and CEO of Optodot. “Boehmite 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.”
The press release provides more:
The patent portfolio includes 20 patents issued in the US, 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 NPORE®, 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.

Good if it results in higher density batteries.
Looks to me like it also isolates cathode and anode better, preventing any spicule formation that might lead to thermal runaway. Good stuff.
Didnt get what this collaboration is about but i think its a kind of utilizing of old generation techs constituents. Lithium ion etc batteries are finishing their gold century. Now its a time for new tech like solar tech, neutrino tech (which was developed by Holger Thorsten Schubart) and other perspective ways for energy.
Prove ’em and someone will use ’em.
Right now the new tech all seems to be ideas, not proven solutions.
No, lots of new tech headed to market now for batteries. The separator tech discussed in this article is an example. Zinc battery with manganese is another example.
After a few years of disappointment I now have a higher standard of “proven”.
The Ambi liquid metal battery was demonstrated at the prototype level but stumbled on the way to market.
I now use “proven” for products that are installed and functioning in the real world.
” offering an unparalleled combination of higher heat resistance and thinner ceramic separators for safer, higher energy density lithium ion batteries.”
solar tech is not battery tech.
From site found when searching “Holger Thorsten Schubart neutrino”
“Many groups worldwide are working quietly to harness this energy source. Neutrino Inc. is such a group leading this revolution.”
Nice science project. …and fusion energy has been just around the corner since WW2. Not ready for deployment yet.
Good news for Bolt
Hopefully the next generation mobilephone of LGs G-series will finally get a bigger battery, lol.
