WHY FIXX?
Built for a Rapid Changing Energy Landscape
Energy infrastructure is evolving quickly, driven by electrification, AI infrastructure growth, grid modernization, and increasing demand for resilient domestic supply chains.
Fixx Energy meets that challenge through disciplined American battery manufacturing and a long-term commitment to reliability, quality, and operational execution.
Everything we do is grounded in three principles.
Purpose.
A clear mission to build the infrastructure that powers a more resilient, more reliable energy future.
Driven.
By an unwavering commitment to safety, operational excellence, and manufacturing quality, and by the belief that energy storage done right changes how the world manages power.
Power.
The kind that reliably flows from our cells into the grids, communities, and industries that depend on them.
Led by experienced industry veterans, Fixx Energy builds on more than a decade of battery manufacturing heritage at its Smyrna facility. Entering its next chapter, the company is focused on advancing American LFP battery manufacturing for the evolving energy storage market.

Technology
Proven LFP Technology. Manufactured with Experience.
Lithium iron phosphate (LFP) has become the leading chemistry for modern energy storage due to its safety profile, long cycle life, and strong economics across grid, industrial, and next-generation power applications.
Fixx Energy builds on more than a decade of battery manufacturing experience and an established U.S. manufacturing platform to produce advanced LFP battery cells designed for demanding energy infrastructure environments.
Proven Manufacturing Heritage
The foundation of reliable battery performance starts with manufacturing discipline, process control, and operational experience.
Fixx Energy builds on manufacturing operations with roots dating back to 2012 at its Smyrna, Tennessee facility, a platform shaped through years of battery mass production experience and continuous operational refinement.
Today, that manufacturing heritage supports the next generation of American-made LFP battery cell production for critical energy infrastructure applications.
Designed for Demanding Infastructure Applications
LFP chemistry is well suited for applications requiring long operational life, high reliability, and consistent performance over extended cycling environments.
These characteristics make LFP an increasingly important technology for utility-scale storage, industrial power systems, and rapidly growing high-uptime infrastructure environments where operational continuity matters.
With long cycle life and strong thermal stability, LFP continues to set the standard for modern stationary energy storage applications.
Safety and Reliability at Scale
In critical infrastructure environments, safety and reliability are essential. LFP chemistry offers strong thermal stability and long-term operational durability, helping support safer and more resilient energy storage deployments.
Fixx Energy builds on a battery manufacturing heritage tied to years of safe, real-world deployment experience across demanding applications. That operational history helps inform a disciplined approach to manufacturing, quality control, and safety-focused execution.
Combined with mature manufacturing processes and operational rigor, Fixx Energy is focused on producing American-made LFP battery cells engineered for dependable long-term performance in modern energy infrastructure environments.
Technology
FIXX ESS Cell Production
The production of lithium iron phosphate (LFP) winding prismatic cells requires highly automated manufacturing processes engineered for precision and consistency at scale. These rectangular, space-efficient cells have become the leading form factor for modern Battery Energy Storage Systems (BESS).
Advanced process controls and intelligent manufacturing systems help reduce variability, identify micron-level defects within milliseconds, and reinforce quality assurance in critical areas including welding precision and foreign object control. This disciplined manufacturing approach supports reliable, high-quality battery cell production for demanding energy infrastructure applications.
