Tesla automobiles do not use the lithium-cobalt-oxide chemistry that is in the Dreamliner batteries. They rely on Panasonic nickel-cobalt-aluminum lithium-ion batteries.Second, Boeing's 'fixes' completely ignore what Elon is saying. The central issue is not just spacing. It's cell size.
Boeing elected to use a battery with a grouping of eight large cells, Tesla's batteries contain thousands of smaller cells that are independently separated.Boeing refuses to address this issue so they will continue to have problems until they do.
