Safer Batteries | U.S. Built
Electrotech Industries is building a U.S.-based manufacturing platform for safety-first sodium-ion energy storage designed for long-life, high-utilization deployment across grid resilience, data centers, telecom, and commercial power.
The Challenge
Electrification, AI workloads, grid congestion, and resilience requirements are driving demand for reliable power. Lithium-ion scaled early adoption, but its limits are now showing:
A Technology Inflection Point
Legacy technologies established the market, but they were not designed for every use case the grid now requires. Electrotech is building the manufacturing foundation for the next generation of storage.
The Chemistry Foundation
Electrotech's platform is built on sodium chromium oxide (NCO) — a sodium-ion chemistry selected for safety, long service life, high utilization, and scalable manufacturing across utility, commercial, telecom, and distributed energy applications.
What Electrotech Builds
Electrotech turns validated demand into standardized, bankable systems — manufactured at scale, without bespoke project complexity.
The Platform
A shared NCO chemistry runs across a portfolio of application-specific products, supported by a repeatable manufacturing foundation built to scale across utility, commercial, telecom, and residential markets.
Utility-Scale
Utility-scale NCO energy storage system engineered for long-duration applications, bankable performance, and repeatable manufacturing across grid, microgrid, and large-site deployments.
High-power GridSpan configuration designed for shorter-duration applications requiring fast response, peak shaving, grid stabilization, and high-utilization dispatch.
Distributed — Commercial, Industrial & Residential
Modular 48V storage platform for telecom, commercial, and distributed sites requiring safe, serviceable backup power.
Expandable behind-the-meter storage for larger C&I and light-industrial sites where modularity, uptime, and deployment simplicity matter.
Compact wall-mounted storage for residential and small commercial applications requiring safe, reliable integration with distributed energy systems.
Core Manufacturing Advantages
Standardized configurations reduce custom engineering, simplify procurement, and improve repeatability across deployments.
Manufacturing-led execution supports shorter delivery cycles and more predictable project timelines.
Domestic sourcing and platform standardization reduce exposure to procurement volatility and imported-battery constraints.
A productized model supports consistent builds, scalable QC, and stronger unit economics as volume increases.
Manufacturing Roadmap
Initial U.S. assembly, supplier qualification, contract manufacturing, and first commercial deployments.
U.S.-based cell production, domestic cathode operations, regional integration hubs, and non-FEOC compliance pathway.
Expanded U.S. manufacturing capacity, multi-GWh annual production, and shorter delivery timelines.
Validation & Bankability
Electrotech is executing a structured validation and certification strategy to support bankable deployments — including third-party testing, insurance-backed warranties, and utility-focused evaluation.
