This one will run and run, if you forgive the pun! I've had conversations with many battery experts and manufacturers that hold this view, but many others don't. Largely those with a V2G or second life battery business model. But many trials are ongoing, including a large one in the UK by CENEX. It will be very interesting to see as the V2G concept is pretty significant in what could be achieved, if batteries aren't shredded in the process.
