Mullen Automotive, an energy technology and electric vehicle (EV) manufacturer, announced the signing of a Partnership and Supply Agreement with Enpower Greentech Inc. (EGI), a global provider of advanced lithium-ion battery manufacturing and technology.
Under the agreement, EGI will support developing and supplying its SWIFT series solid-state battery (SSB).
The SWIFT SSB is designed for various applications beyond commercial vehicles, including aerospace, marine, drone systems, hobby vehicles, and other industrial sectors requiring high-performance energy solutions.
The agreement between the parties outlines the partnership to manufacture the SWIFT SSB modules and battery packs domestically at Mullen’s Battery Center in Fullerton, California. The Fullerton Center has three lines for manufacturing lithium-iron-phosphate (LFP) battery modules. It will continue to ramp up its engineering staff for full production and to execute this technology in early 2026.
Mullen’s Fullerton facility currently has three battery lines installed in support of US-made battery components and manufacturing. Lines include:
- High volume standard battery chemistry line
- Low volume standard chemistry R&D line
- Low volume solid-state polymer R&D line
EGI’s SWIFT Series SSB Cells are advanced silicon-anode-based semi solid-state batteries. They offer twice the energy density, ultra-fast charging capability, extended cycle life, and a cost-efficient manufacturing roadmap. Some of the top US automotive OEMs, drone manufacturers, and eVTOL companies have widely tested and validated SWIFT cells.
EGI plans to commence domestic manufacturing in late Q3 2025 at its Ann Arbor, Michigan, facility, which will continue to expand its manufacturing capacity throughout 2026. This way, EGI will offer tariff-free, high-performance pouch cells to the market.
