A type of battery that could eventually store twice as much energy as a conventional one could be about to move beyond niche applications to wearable devices, phones, and even electric cars.

Solid-state batteries, as they’re called, have been available for a while and are used in some wireless sensors, but they have been too expensive to use elsewhere. Applied Materials, one of the world’s biggest equipment suppliers for the semiconductor and display industries, says it can make these batteries much cheaper. This could clear the way for slimmer, longer-lasting smart watches as well as electric cars with a range similar to gas-powered ones.
