Fisker shows off its solid state battery for cell phones and cars

Electric car maker Fisker is showing the first stages of its high capacity solid stage battery for both mobile hones and electric vehicles.

A working battery in a case and a bulk battery without a case (above, showing the 3D electrode scaffold) are being shown at CES 2018 in Las Vegas this week. The working battery will be half the size of a cell phone battery, 2mm thick and with 'superior' energy storage 2.5 times that of lithium ion batteries says the company.

The researchers at Fisker include the former co-founder of battery technology developer Sakti3 (later bought by Dyson) who has filed patents on flexible solid state batteries with higher energy density. The solid-state batteries will feature three-dimensional electrodes to get the higher energy density with charing times as low as 1 minute and a range of over 500 miles, compared to 300 miles today. 

Batteries for automotive applications are expected to be in production 'sometime' after 2020, but Fisker is planning batteries for mobile phones earlier than that, possibly by the end of this year.

"We are truly entering a new era in the way the world thinks about vehicles, the way EVs are charged and the way personal consumer electronics are powered – with Fisker now clearly at the forefront of that revolution through our worldwide launches at CES," said Henrik Fisker, chairman and CEO of Fisker. "We've made the seemingly impossible, possible with our scientists spearheading the breakthrough in Flexible Solid-State battery technology – which is the next generation in charging everything from your personal cell phone to enabling mass adoption of electric vehicles due to unprecedented ranges and lighting fast charge times. We're incredibly excited to showcase working solid-state batteries and the vehicle."

The Fisker EMotion electric car will be produced in the US at a location to be announced during the second half of 2018, but using traditional lithium ion battery cells, giving it a range of 400 miles and a top speed of 161mph. It will also use five solid state Lidar sensors from Quanergy to provide autonomous operation up to level 4, one
