The importance of batteries has taken a new life with the advent of electric cars. Now that more studies are being made on how to improve batteries, we can at least expect a few of these researchers to have some kind of breakthrough. Take this one from the University of Waterloo. Researchers from the university have released a new paper claiming a breakthrough in the use of negative electrodes made of lithium metal. How is this relevant to the auto industry? The short answer is that it could potentially triple the range of electric vehicles.
