Further, Boeing's indications that heat damage in one battery cell would not harm adjacent cells proved false, Hersman said.
SUMINOE, JAPAN, Thursday, April 22nd - Tesla officials today visited Panasonic's new Lithium-ion battery cell manufacturing facility in Suminoe, Japan.
Boeing has suggested an electrical insulator that wraps around each battery cell to isolate each cell from each other and the battery case.
The tests also failed to spot that overheating in one battery cell could cascade to the others, causing a fire, the NTSB added.
Many companies are working on coming up with better materials for the cathode or the anode in order to increase the energy density of the battery cell.
