Battery researcher Jeff Dahn: Why the million-mile battery makes sense
The battery research team around Jeff Dahn continues to work on the million-mile battery. As the Tesla battery researcher explained at an online conference, the actual goal is not to make an electric car drive 1.6 million kilometres with it but to be able to use the battery in V2G applications.
