American EV manufacturer, Fisker, claims a 500-mile range and greater performance for its advanced new battery tech

Electric vehicle manufacturer Fisker has patented potentially industry-changing solid-state battery technology. The American manufacturer claims the technology has the ability to power a car for over 500 miles on a single charge and aims to introduce it to its model line up in 2023.

The Californian marque has partnered with Dyson-owned solid-state battery specialists Sakti3 to develop the new and unconventional battery system for use in its future EVs. The technology involves the construction of bulk three-dimensional solid-state electrodes with 25 times more surface area than traditional thin solid-state electrodes. This enables faster charging and better performance in cold temperatures. Energy density from solid-state batteries is said to be 2.5 times greater than traditional lithium-ion batteries and is projected to cost one third of the price.

Development of solid-state batteries for vehicle use has been slow, due to the lack of supply chains for the specific raw materials needed to assemble the battery pack. The quality of the materials and the finished solid-state battery itself is currently a long way off mass production standards before Fisker decides to implement the technology.

Should the solid-state breakthrough occur, Fisker claims that solid-state-powered EV’s could have a range of over 500 miles on a single charge. It also claims charging times could be as low as one minute, but does not specify whether the battery can be fully or partly charged in the space of 60 seconds.

While solid-state batteries remain a few years away from being implemented in new cars, Fisker will showcase the solid-state battery tech at the upcoming Consumer Electronics Show in Las Vegas on 9-12 January 2018. It will be displayed alongside Fisker’s new EMotion, a 161mph four-door electric saloon with a range of 400 miles, which will rival the market-leading Tesla Model S.
