What Liion does
LiiON, LLC is a US-based lithium-ion energy storage solutions provider founded in 2009 and headquartered in East Dundee, Illinois. The company designs and sells UL-certified lithium-ion battery systems, including the first UL Certified Lithium-ion High-Rate Battery System for UPS applications, alongside its proprietary eOS Energy Operating System — a patent-pending platform that combines real-time energy monitoring with an AI-driven blockchain protocol for data and grid security. LiiON's product portfolio spans SES UL-certified battery systems for data centers, the LBRS lead-acid battery replacement retrofit, modular Energy Containers, and Microgrid Solutions, addressing UPS backup, peak shaving, load management, and grid resilience use cases.
The company operates a direct enterprise sales motion targeting data centers, industrial facilities, and critical infrastructure customers across North America, with named reference customers including Amazon, Walmart, and NASA, and a cumulative installed base of more than 250 systems representing 12+ million hours of safe operating history. Revenue is generated primarily through hardware sales of battery systems and LBRS retrofits, supplemented by subscription/recurring revenue from the eOS smart energy management layer, with pricing positioned at parity with lead-acid alternatives but at roughly three times the operational lifespan.
In January 2025, LiiON was acquired by Alternus Clean Energy in a $5 million asset purchase, and in April 2026 it joined the DOE-funded Critical Facility Energy Resilience (CiFER) consortium with Eaton, Pacific Northwest National Laboratory, Binghamton University, and Electrovaya to develop larger-scale energy storage for data centers and critical infrastructure. Despite a 15-year operating history, the company remains a small organization with 1-10 employees and a minimal direct digital footprint, with its public-facing website still under reconstruction.
