Toyota wants to take your range anxiety out for a walk behind the woodshed and obliterate it from the known world. The means for doing this, the Japanese giant has revealed, might very well be contained in its new magnesium-sulfur batteries, which promise to double the energy density of the current industry-best lithium ion cells. Of course, the catch here is that the new magnesium goodness is nowhere near ready and is projected to come in 2020 at the earliest, but we're gladdened to see a long-term view being taken by car manufacturers with regard to powering vehicles electrically. Alternative methodologies currently under review in Toyota's labs also include aluminum and calcium materials, showing that there is indeed no lack of ambition for making plug-ins respectable road warriors.
