Fisker’s scientists have reached an early breakthrough in solid-state technology. The wider team includes the co-founder of solid-state battery technology pioneer, Sakti3 – a first inventor of the seminal patents. Implications for Fisker’s vehicles beyond 2023 – as well as the larger EV industry as a whole – are significant. The patent includes claims over novel materials and manufacturing processes that are critical in achieving the required energy density, power and cost targets that are paramount for the widespread use of electric vehicles.

Fisker Inc.’s Scientists File Patents on Superior Energy Density Tech, Shattering Conventional Thought on EV Range and Charge Times

  • Fisker’s scientists, including the co-founder of global battery tech pioneer Sakti3, filed patents this week on flexible, superior energy density solid-state batteries.
  • Breakthrough technology will enable dramatically longer 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.
  • Automotive applications anticipated to be production grade ready from 2023 onwards.
  • Fisker’s solid-state batteries will feature three-dimensional electrodes with 2.5 times the energy density of lithium-ion batteries.

 

REVOLUTIONARY SCIENCE. MULTIPLE INDUSTRY FIRSTS

  • Current limitations in solid-state technology include low electrode current density, limited temperature ranges, limited materials availability, high costs and non-scalable manufacturing processes.  Early results show that Fisker’s solid-state technology enables the construction of bulk three-dimensional solid-state electrodes with 25 times more surface area than flat thin-film solid-state electrodes and extremely high electronic and ionic conductivities – enabling fast charging and cold temperature operationAs a result, Fisker’s battery delivers 2.5 times the energy density of typical lithium-ion batteries – with the potential of costing one third of the 2020 projected price of those batteries due to advances in materials and manufacturing.
  • Several failure modes affect solid-state batteries, including low power and low rate capability due to high contact resistance and low ionic mobility in the layered electrode structures. Delamination issues due to volume changes and residual stresses during charge/discharge processes; dendrite penetration and stability vs. metallic lithium electrodes; and low ionic diffusion, particularly in low temperature climate due to solid-state material limitations, are also roadblocks. With the newly announced technology, Fisker’s scientists are addressing these technical bottlenecks.

  • Fisker anticipates the technology may be ready for automotive applications post 2023. Such long lead times are due to the lack of supply chains with particular raw materials and appropriate manufacturing tools, as well as established quality procedures for materials repeatability. Once the technology is fully validated, the battery will deliver a vehicle range of more than 500 miles on a single charge, and charging times as low as one minute – allowing technology to bypass the internal combustion engine and push the automobile into mass electrification. Fisker is in active discussions with various industrial groups around potential non-automotive partnerships – with the possibility of battery applications that may be commercialized much earlier than 2023.
  • Fisker’s flexible solid-state electrode construction will enable batteries with versatile voltage and form factors. They may be wound in cylindrical cells with higher voltage output, allowing usage of current tooling and machinery for battery packs – in addition to lesser cell-to-cell connections, thermal management and safety requirements. This further reduces battery system costs.

 

THE FISKER EMOTION LUXURY ELECTRIC FOUR-DOOR SEDAN: CES 2018 LAUNCH.

  • The much-anticipated 2018 launch of the Fisker EMotion luxury electric vehicle at the Consumer Electronics Show will showcase a proprietary battery module with advanced thermal management using 21700 NCM cells from LG Chem. The company has been simultaneously working on proprietary technology that will enable charging for a 127-mile range in nine minutes. Fisker’s solid-state battery and extreme fast charging technologies will be on full display at the vehicle’s launch at CES.

“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.”

“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.”
