What Amionx does

Amionx is a private battery safety technology company headquartered in Carlsbad, California, founded in 2016 as a spinout from American Lithium Energy (ALE). ALE had developed advanced custom batteries for military applications — including unmanned vehicles, weapons systems, and a U.S. Army-commissioned bullet-safe battery — and had received a Department of Energy ARPA-E grant to study ultra-safe battery packs for electric vehicles. Amionx was created to commercialize the resulting SafeCore technology, which originated from that military and DOE-funded research.

SafeCore is a proprietary, trade-secret-protected material layer added at the cell level during lithium-ion battery manufacturing. When a cell approaches thermal runaway from internal short, overcharge, impact, or heat, the material physically separates key components inside the cell, cutting off electrical flow before fire or explosion can occur. Unlike battery management systems that respond to symptoms after onset, SafeCore acts as an internal fuse at the cell level. The company emphasizes ease of integration: virtually no increase in bill of materials, no major capital expenditures, no increase in cycle time, and implementation within six months at the manufacturer's existing facility.

Amionx operates as a B2B technology licensing business, targeting lithium-ion battery manufacturers serving electric vehicles, consumer electronics (smartphones, laptops, power banks), and grid-scale energy storage. Revenue derives from licensing and royalty arrangements with these manufacturers rather than direct product sales. Its only publicly named commercial partner is Powerbanc Group, which is implementing SafeCore in consumer power bank products. The company has raised approximately $11 million cumulatively across a 2017 round led by Qualcomm Ventures and a 2021 Series B led by Hongkou Management and Inherent Group alongside Qualcomm Ventures.

Core offering

Amionx licenses its proprietary SafeCore safety technology to lithium-ion battery manufacturers for integration during cell production. SafeCore acts as an internal fuse within the battery cell, creating a physical gap between key components when overheating threatens thermal runaway, thereby shutting off electrical current and preventing fire or explosion. The technology is sold to manufacturers of EV batteries, consumer electronics batteries, and grid-scale energy storage systems.

Product overview

Amionx offers SafeCore as its primary and only product—a battery safety technology that prevents lithium-ion batteries from starting fires. SafeCore is a single core technology that integrates directly into battery cells during manufacturing, acting as an internal fuse mechanism. The technology was developed from military research (originating from American Lithium Energy's work with the U.S. Army and Department of Energy) and is designed for application across electric vehicles, energy storage systems, and consumer electronics including power banks. The company operates as a spinout from American Lithium Energy (ALE), which manufactures custom batteries for military applications.

Direct peers

• KULR Technology Group: KULR develops thermal management and runaway prevention solutions for lithium-ion batteries across EV, aerospace, and energy storage applications. Directly comparable to Amionx in targeting cell- and pack-level battery safety with a B2B technology offering.
• Microvast: Microvast is a lithium-ion battery cell and pack manufacturer that emphasizes safety features, including thermal runaway prevention chemistries and separator technologies. Comparable to Amionx in addressing lithium-ion safety, though at the cell-maker level rather than as a licensable safety layer.

Emerging players

• Enevate: Enevate develops silicon-dominant Li-ion battery technology for EVs with claims of faster charging and improved safety characteristics. Comparable to Amionx as an emerging player pushing lithium-ion safety/performance boundaries, though through cell chemistry rather than a discrete safety layer.
• Sila Nanotechnologies: Sila produces silicon-anode battery materials aimed at improving energy density and safety for EVs and consumer electronics. Comparable to Amionx as an emerging battery-materials innovator licensing into major cell makers, though its mechanism (anode chemistry) differs from SafeCore's cell-level fuse.
• QuantumScape: QuantumScape is developing solid-state lithium-metal batteries marketed in part on intrinsic safety advantages over conventional Li-ion. Comparable as an emerging player whose commercial thesis depends on improved Li-ion safety, though targeting alternative chemistry rather than a drop-in safety layer.
• Solid Power: Solid Power develops all-solid-state battery cells with safety and energy density benefits for EVs. Comparable as an emerging next-gen battery player competing for the same OEM safety-driven design wins that Amionx targets.
