Lithium-ion battery thermal runaway is the cancer of energy storage applications.

Energy Storage


As demand grows for more powerful portable electronics, battery powered tools, and electric vehicles, there is need for battery systems to effectively meet increased power and energy density requirements. Because of their energy density, higher voltage, and negligible memory effects, lithium-ion batteries are the popular choice for a wide range of applications, especially in portable electronics. However, larger power demands and increasing cell density of lithium-ion battery packs result in higher operating temperatures, especially under peak loads. Although rare, news of exploding electronic devices due to thermal runaway in lithium ion batteries (Li-B) are well documented and raise serious safety concerns.

Li-B cells with cobalt cathodes should never rise above 130°C (265°F). At 150°C (302°F) the cell becomes thermally unstable causing a condition that can lead to thermal runaway in which flaming gases are vented. During thermal runaway, the high heat of the failing cell can propagate to adjacent cells causing them to become thermally unstable as well. To increase safety, packs are fitted with dividers to protect the failing cell from spreading to neighboring cells.


KULR has developed a cost effective passive thermal management system to prevent Li-B thermal runaway. KULR’s proprietary system offers design simplicity and eliminates the need for costly mechanical equipment and additional capacity to power them.
