When Henrik Fisker relaunched its electric car startup last year, he announced that their first car will be powered by a new graphene-based hybrid supercapacitor technology, but he later announced that they put those plans on the backburner and instead will use more traditional li-ion batteries.

Now the company is announcing a “breakthrough” in solid-state batteries to power their next-generation electric cars and they are filing for patents to protect their IP.

Get ready for some crazy claims here.

Solid-state batteries are thought to be a lot safer than common li-ion cells and could have more potential for higher energy density, but they also have limitations, like temperature ranges, electrode current density, and we have yet to see a company capable of producing it in large-scale and at an attractive price point competitive with li-ion.

Now Fisker announced that they are patenting a new solid-state electrode structure that would enable a viable battery with some unbelievable specs.

Here’s what they claim (via GreenCarCongress):

“Fisker’s solid-state batteries will feature three-dimensional electrodes with 2.5 times the energy density of lithium-ion batteries. Fisker claims that this technology will enable ranges of more than 500 miles on a single charge and charging times as low as one minute—faster than filling up a gas tank.”

Here’s a representation of the three-dimensional electrodes:

Fisker has been all over the place with its new Emotion electric car and we have highlighted that in our look at Fisker’s unbelievable claims.

But its latest solid-state project is led by Dr. Fabio Albano, VP of battery systems at Fisker and the co-founder of Sakti3, which adds credibility to the effort.

Albano commented on the announcement:

“This breakthrough marks the beginning of a new era in solid-state materials and manufacturing technologies. 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.”

Electrek’s Take

Like any battery breakthrough announcement, it should be taken with a grain of salt. Most of those announcements never result in any kind of commercialization.

For this particular technology, Fisker says that it will be automotive production grade ready around 2023.

A lot of things can happen over the next 5 years.

In the meantime, Fisker plans to launch its Emotion electric car at CES 2018 in just 2 months. Fisker already unveiled a prototype of the new electric car and started taking pre-orders this summer.
