If there is one thing that is on every smartphone owner's wish list, it's a longer-lasting battery.
SolidEnergy Systems, founded by MIT alum Qichao Hu, may have a solution. The 4-year-old firm developed a rechargeable lithium metal battery, which it claims can double the energy capacity of a regular lithium ion battery found in most modern gadgets.
By swapping graphite—a common battery anode—for SolidEnergy's ultra-thin metal material, the battery produces twice as much energy density, while still operating safely at high temperatures.
