Separately, shares of KULR Technology Group KULR shares jumped on Thursday after the company received a permit from the U.S. Department of Transportation certifying that its packaging for lithium cells and batteries is safe for air freight.
Prototype lithium batteries can be transported on cargo-carrying aircrafts to, from and within the U.S. only when the Transportation Department approves them.
