Ateios

Ateios Systems (Ateios) is a battery technology company that develops electrode manufacturing processes and materials intended to raise production speed while lowering cost, energy use and factory footprint. Its platform, branded RaiCure, is presented as a drop-in electrode coating solution for existing manufacturing lines. The company states its electrodes reach loadings above 10 mAh/cm2 with approximately 50% higher density, roughly 20% cost reduction, five-times production speed, and claimed reductions of 98% in operating expenditure, 75% in capital expenditure and 98% in emissions. The materials are described as chemistry-agnostic, PFA-free verified and recyclable.

The company's earlier work centered on thin, flexible, customizable batteries for wearables, IoT devices, medical devices and other flexible electronics, using a "cure-on-command" process that shortens component curing from hours to seconds and allows electrodes and cells to be die-cut into custom shapes and applied robotically. Ateios supplies battery manufacturers with recyclable, solvent-free electrodes and also positions itself as a provider of advanced battery, materials and software solutions. Product releases have been described across major lithium-ion chemistries including LCO, LFP and NMC, with the stated aim of scaling to GWh volumes and supporting a domestic battery supply chain.

The company operates a sampling funnel in which prospective customers answer qualifying questions to receive a sample electrode or battery along with production estimates.

Founding story

Ateios was founded in 2018 by Rajan Kumar, PhD, together with fellow graduate student Carlos Munoz, out of research on stretchable batteries at the University of California San Diego Jacobs School of Engineering. After spinning out and engaging early customers in wearables and the Internet of Things, the team developed a patent-pending manufacturing technique for thin-film batteries.

Business model

Ateios sells electrodes and battery manufacturing technology to battery producers and device makers, offering its coating process as a drop-in replacement within existing production lines and providing custom form-factor cells. Customer engagement begins with sample electrodes or batteries and production estimates.

Revenue is derived from supplying electrodes, batteries and related battery, materials and software solutions to manufacturers and device makers.

Traction

The technology attracted customers in the flexible electronics industry prior to the 2020 seed round, and the Battery Innovation Center provided equipment and facilities enabling regular commercial-quantity battery deliveries. Work with Eastman Kodak has been publicly cited by the company, and the company reports plans to scale to GWh volumes with product releases across LCO, LFP and NMC chemistries. TechCrunch lists $9.1 million raised as of January 1, 2025.

Latest developments

Ateios Systems announced the close of a $7.25 million Series A to scale next-generation battery electrode manufacturing, with proceeds directed toward R&D on the electrode platform, production capacity and hiring.
