Tesla Inc has expressed its interest in producing a new battery for its Model 3 sedan vehicles in China that will last for a million miles, according to reports from Reuters.
The new battery won’t only extend the life of electric vehicles, Tesla believes it will also bring the cost of EV’s down to the point where they’re on par with conventional petrol powered vehicles.
The new “million mile” battery strategy was jointly developed with China’s Contemporary Amperex Technology Ltd (CATL) and makes use of technology developed by Tesla in collaboration with a team of academic battery experts recruited by Musk.

It was exclusively reported by Reuters in February that Tesla was in advanced talks with CATL to use its lithium iron phosphate batteries, which don’t use any cobalt to manufacture. Cobalt is the most expensive metal in current EV batteries.
Along with developing lithium iron phosphate batteries, CATL has also developed a less expensive way to package its batteries. Called ‘Cell-to-pack’, this method eliminates the middle step of having to bundle cells when installing it into the vehicle. Tesla is expected to use the technology to help reduce both the battery weight and cost of its vehicles.
“We’ve got to really make sure we get a very steep ramp in battery production and continue to improve the cost per kilowatt-hour of the batteries — this is very fundamental and extremely difficult,” Musk told investors in January. “We’ve got to scale battery production to crazy levels that people cannot even fathom today.”
