Kulr Technology in the US has teamed with NASA on safety and thermal management technologies that can be used for lithium ion battery packs in space.
The carbon fibre passive propagation resistant (PPR) battery design for lithium ion battery safety prevents cell to cell thermal runaway propagation and restricts the fire and explosion of a single cell thermal runaway from exiting the battery enclosure.
Kulr currently works with NASA’s Marshall Space Center and NASA’s Ames Research Center on the PPR CubeSat battery design to meet the JSC 20793 Revision D safety standard created by NASA for a crewed space mission. Kulr’s HYDRA thermal runaway shield technology was recently deployed to the International Space Station to store laptop batteries and also is currently being tested by a Tier-1 medical device maker, an electric aircraft maker and others.
The PPR design combines Kulr's HYDRA thermal runaway shield and LYRA internal short circuit testing methodology with NASA’s Fractional Thermal Runaway Calorimeter cell analysis technology to provide total battery safety. The HYDRA thermal runaway shield has been proven by various government testing authorities to stop or mitigate the impacts of dangerous lithium-ion battery failures.
“Battery safety is crucial in aerospace settings like those being built by and for NASA,” said Michael Mo, CEO of Kulr Technology. “The PPR solution developed by KULR may be the best possible defense against thermal runaway propagation which explains NASA's interest in our technology.”
