As Simon will always question, charging a battery that can run a car for 500 miles in one minute will need a pretty impressive set of cables to do so. This claim may be realistic in that they are looking 6 years out before commercial production.
Electric car-maker Fisker has filed patents for flexible solid-state battery technology that could slash charging times and improve range.
- The new battery uses a three-dimensional structure to increase surface area
- Fisker says it could allow for 500 mile range, and charging in just one minute
- The technology will be on display at the Consumer Electronics Show in Jan
2.5 times the energy density of typical lithium ion
According to Fisker, the radical new battery would deliver 2.5 times the energy density of typical lithium ion batteries.
Solid-state batteries are known to have a number of limitations, such as low power and low rate capability as a result of the layered electrode structure, and issues arising from cold temperatures, the firm explains.
But, the new technology attempts to overcome the challenges using a three-dimensional solid-state structure.
This allows the electrodes to cover 25 times more surface area than flat thin-film designs.
‘This breakthrough marks the beginning of a new era in solid-state materials and manufacturing technologies,’ said Dr. Fabio Albano, VP of battery systems at Fisker Inc.
‘We are addressing all of the hurdles that solid-state batteries have encountered on the path to commercialization, such as performance in cold temperatures; the use of low cost and scalable manufacturing methods; and the ability to form bulk solid-state electrodes with significant thickness and high active material loadings.
‘We are excited to build on this foundation and move the needle in energy storage.’
Making the impossible, possible
‘Our aggressive vision for the entire EV and automotive industry, not just for Fisker Inc., revolves around making the impossible, possible – and this global solid-state battery breakthrough is reflective of our utmost seriousness in making that vision a reality,’ said Henrik Fisker, chairman and CEO of Fisker Inc.
‘It used to be about the efficiency of the gasoline engine. Now, it’s all about who breaks the code and smashes the barriers to future battery technologies that will enable mass market electrification.
‘Our scientists have been working tirelessly to deliver. We’ve done it, and this is just the beginning.’
