Ultium Cells Spring Hill Begins LG Energy Solution JF2 LFP Battery Cell Production for Energy Storage Systems

General Motors and LG Energy Solution have reached another milestone in their battery manufacturing partnership as Ultium Cells Spring Hill officially launched production of LG Energy Solution's JF2 lithium iron phosphate (LFP) battery cells for energy storage systems (ESS) on July 7. The development broadens the facility's manufacturing capabilities beyond electric vehicle batteries while reinforcing domestic battery production in the United States.

Spring Hill Facility Expands into Energy Storage

The newly manufactured JF2 LFP battery cells will be supplied to LG Energy Solution Vertech for integration into complete energy storage systems produced in the United States. These storage systems are designed to satisfy domestic content requirements, supporting customers seeking locally manufactured energy storage solutions while strengthening the country's battery supply chain.

Rapid Production Conversion Demonstrates Manufacturing Flexibility

The Spring Hill plant, operated as a joint venture between General Motors and LG Energy Solution, completed the conversion of part of its existing manufacturing capacity to LFP battery cell production in fewer than five months. This relatively short transition highlights both the operational flexibility of the facility and the expertise of its workforce in adapting production lines for new battery technologies.

Operations Resume While EV Battery Production Continues

As production volumes increase, all employees at Ultium Cells Spring Hill have returned to work following a temporary hiatus that occurred during the facility's upgrade process. Alongside the new energy storage battery program, the plant continues manufacturing electric vehicle battery cells, allowing the site to support both mobility and stationary energy storage applications.
