Fisker is parting ways with battery technology supplier Nanotech Energy for the upcoming EMotion all-electric luxury sports sedan.

Its Fisker Nanotech joint venture was going to use battery cells made from graphene for the EMotion’s battery pack. The JV, called Fisker Nanotech, came to be with founder Henrik Fisker’s announcement of Fisker Inc., in October 2016.

The EMotion will instead receive its power through advanced cylindrical lithium-ion NCM chemistry cells provided by LG Chem, Fisker said.

Nanotech Energy had its plate full with Fisker, neglecting other client projects.

“In order to meet the timetable for Henrik Fisker, we would have had to just focus on that and that alone,” said Jack Kavanaugh, chairman and acting CEO of Nanotech Energy. “It wasn’t right for us as a company to just focus on one thing.”

Fisker had been vocal about Fisker Nanotech last fall with introduction of the EMotion. That battery was going to bring 400 miles of range, and able to receive 125 miles worth of recharging in just 9 minutes. It would support a drive train capable of hitting a top speed of 161 mph.

Fisker said changing over to LG Chem won’t hurt those performance metrics.

Graphene is known for providing a very strong structural element, Kavanaugh said. That helps charge and discharge cells faster while improving safety and range. The cells could come from another source like lithium ion.

The electric carmaker will continue to “work with Nanotech on the applications of graphene,” but it will use battery cells provided by LG Chem in the EMotion, Fisker said.

The battery cells will come from LG Chem, which Fisker said his company is confident will provide what they need for power and fast charging.

Fisker Inc. will continued working on sold state battery technology, but that will be a few years out. Solid state batteries replace the liquid electrolyte used in lithium ion batteries with a solid one. They’re capable of being more compact and stable, allowing for more voltage to be stored in a smaller battery pack.

“We are enhancing and expediting our efforts in solid-state technology and will be announcing our recent developments and partnerships on the near future,” Fisker said.

Fisker said that technology remains five to seven years away, if not more. Going mass market with solid-state batteries will happen sometime “ahead of 2025.”

The startup automaker has been receiving refundable $2,000 deposits for the EMotion. Without giving numbers, Fisker said that 2019 delivery goals have already been met with down payments. Future deposits will to Emotions released in 2020.

Fisker had a previous fallout with a battery technology supplier. A123 Systems provided the battery packs for the Fisker Karma until it went out of production in late 2012.

Fisker had been given enough batteries for Karma production until the first part of 2013, but the company had gone through upheaval losing much of its inventory. That came from Hurricane Sandy flooding a New Jersey port in November 2012, destroying 338 Karmas.

Fisker Automotive filed for bankruptcy in 2013, following A123 System’s filing in October 2012. Both companies were purchased in their BK settlements by Chinese auto parts giant Wanxiang Group.
