The MIT company, SolidEnergy has made a huge advancement in energy storage technology with the development of a lithium-ion battery cell capable of holding the same amount of energy in half the size of its ion counterpart — meaning your phone battery could double in life, and electric cars can go twice the distance on one charge. The new cell replaces carbon anodes with a thin lithium foil anode which helps reduce the battery’s size dramatically. The new design also incorporates a solid electrolyte coating which prevents overheating, as well as a non-flammable liquid electrolyte. Drone batteries are expected to debut on the market November of this year, with smartphone batteries to follow in 2017 and EV batteries in 2018
