your computer generated pic is full of air "The site at Harker, near Carlisle, will be powered by a £25m battery complex that will be under construction soon." was to be finished 2019 , is it ? I can see the idea and its cheaper than trying to recycle which is proving very difficult to say the least , but these units will become scrap , as for mining , we have been for over 100 years so I see there is a lot more information studies etc , in the short EV evolution I can already see some massive problems appearing but as usual economics/money are guiding they way. I am still not convinced but need to go a mow the lawn (Kawasaki petrol) so will think about it
