Hmmmm…

Fisker has filed patents for solid-state batteries

So what makes this newsworthy? The claims:

• 2.5 times the energy density of current batteries
• A car would have a 500-mile range
• It would take only one minute to charge that car
• Cheaper than lithium ion batteries
• Lower risk of fire

The target is electric cars. But 2.5 times the energy density means laptop batteries that last far long, cell phones that last for days, electric aircraft from drones to airliners, man-portable lasers and railguns/coilguns capable of meaningful performance.
