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.
"With two times the energy density, we can make a battery half the size, but that still lasts the same amount of time as a lithium ion battery," Hu told MIT News. "Or we can make a battery the same size as a lithium ion battery, but now it will last twice as long."
Plus, the SolidEnergy battery can be manufactured using existing Li-ion infrastructure, making them easier to produce in bulk for a host of devices. The technology will arrive in drones this fall, before rolling out to smartphones and wearables in 2017, and electric cars in 2018.
