[font size=4]The batteries should last twice as long as comparably sized rivals.[/font]

[font size=3]Scientists have known for decades that lithium-metal batteries offer a powerful combination of energy density and compactness. Unfortunately these batteries also present challenges: they are difficult to recharge and they have an unfortunate tendency to burst into flame.
Boston-based startup
SolidEnergy Systems, spun out of
the MIT lab of Donald Sadoway in 2012, claims to have solved these problems with a novel anode structure and hybrid electrolyte. Qichao Hu, SolidEnergys founder, first showed a prototype last fall that is half the size of an iPhone 6 battery and offers more battery life per charge. The company says it will sell batteries for smartphones by early next year, and for electric vehicles in 2018. First, though, its going after a more specialized market: drones.
Specifically, Hu points to the high-altitude drones and balloons being developed to provide Wi-Fi in remote areas. They need to be powered by batteries, but the current lithium-ion battery lifetime is very short and the batteries are heavy. SolidEnergys new battery, he says, provides the same capacity at half the volume and half the weight.

Selling batteries for drone makers could be a clever means of entry for a new battery company, many of which have had trouble competing with established battery providers like Panasonic, which has a multi-billion-dollar contract to supply electric-car maker Tesla with batteries. But while SolidEnergys technology is novel, it is still unproven at the scale necessary to grab a portion of the growing drone market, to say nothing of cell phones and electric vehicles.
