Batteries are no longer boring. Whether catching fire in Samsung Note 7s, being hailed as the answer to future electricity grids thanks to breakthrough chemical innovation, or being manufactured on a gigantic scale in Elon Musk’s gigafactory in Nevada, batteries are box office. And though battery technology is indeed advancing by leaps and bounds, there is a considerable quantity of balderdash being talked about it too.
If only we could store electricity! Then we could make it in the summer sun and on windy days, for use on cold winter nights.
