JB Straubel, one of Tesla's five co-founders and long-time chief technology officer of the EV maker, believes electric vehicle batteries should last for about 15 years.
Straubel is an authority on batteries as he was responsible for Tesla's battery development until 2019. He led cell design, supply chain and the first Gigafactory concept through the production ramp of the Model 3.
After leaving Tesla, the engineer focused on Redwood Materials, a company he founded in 2017 with the goal of providing end-of-life solutions for batteries from electric vehicles, hybrid vehicles, and even cellphones.
