DETROIT (Michigan News Source) – The investment portion of automaker Stellantis has announced an agreement with California-based battery maker Lyten Incorporated. The $323 million investment is aimed at helping double revenue for the car company by the year 2030.

Lyten makes lithium-sulfur battery packs that they claim can double the energy density of current batteries and improve driving range and payload issues.

Lyten’s batteries do not use nickel, manganese and cobalt that is found in many lithium-ion batteries. According to Lyten, the key is the company’s proprietary “3D graphene” supermaterial. Although 2D graphene has been around since 2004, winning a Nobel Prize in 2010, Lyten took it a step further by taking it from the lab to commercial applications.

However, there are concerns about the longevity of a lithium-sulfur battery and how it could be recycled.
