$KULR Prior to KULR, Dr. Walker was employed by NASA Johnson Space Center where his career primarily focused on the design and optimization of safe lithium-ion (Li-ion) battery assemblies for human spaceflight applications. More specifically, he focused on the thermal management of Li-ion battery assemblies, battery safety in general, and the development of new calorimetric techniques for thermal runaway characterization. Dr. Walker is also a co-inventor of NASA’s recently patented Fractional Thermal Runaway Calorimetry techniques which provide the capability to discern the fraction of thermal runaway energy ejected away from the Li-ion cell versus that which remains with the cell. https://finance.yahoo.com/news/kulr-technology-group-appoints-dr-130000251.html
