TRS suppresses potentially catastrophic thermal runaway (rapid jump in temperature) in lithium-ion battery packs and is now in use aboard the International Space Station

KULR Technology Group Inc () won a second US patent for its Thermal Runaway Shield (TRS) a passive propagation resistant solution designed to reduce the hazardous associated with thermal runaway (rapid jump in temperature) in lithium-ion battery packs.

The companys TRS is a sleeve-like shield that surrounds and separates individual cells in multi-cell packs and contains carbon fiber core and liquid coolant to keep an exploded cell from causing a catastrophic fire through the entire battery pack.

The unique combination and configuration of the shield passively draws intense heat of cell failures away from nearby cells while dousing the failed area in a cooling and fire-prevention liquid.

The TRS product is used by NASA to transport to and store batteries aboard the International Space Station.

Securing this patent is a substantial leap forward in our research and development of products that make batteries safer, Timothy Knowles, co-founder and chief technology officer of KULR, said in a statement Wednesday.

We are very pleased with the development of our patent portfolio. This new issuance expands the breadth and depth of our battery safety technology covering catastrophic battery failures.

In a comprehensive analyst report by Litchfield Hills Research last month, the firm estimated that KULR's technology has an addressable market of $8 billion.

Both the growth of electric-motor based transportation and demand for increased safety of lithium-ion batteries are key drivers for KULR, the report said. KULR has what we believe to be better and lighter materials for thermal management.

Michael Mo, CEO of KULR, added: Battery safety is a global concern across many large and rapidly growing markets such as electric vehicles, battery storage, 5G infrastructure, and space exploration. We continue to work with government agencies, regulators and commercial customers across the world to deploy our technology.

Campbell, California-based KULR's stock recently traded up by 1% to $1.31 a share in New York.
