Eonix

Eonix is a technology company specializing in the development of advanced materials aimed at enhancing the performance of lithium-ion batteries. Founded in 2020 by Don DeMuth and Austin Sendek, the company is headquartered in Salt Lake City, Utah. The founders bring a blend of industrial and academic expertise to the firm. Don DeMuth has a background in scaling materials companies, while Austin Sendek holds a PhD in Applied Physics from Stanford and has experience in computational materials science, previously founding Aionics, Inc.

The core of Eonix's business is the creation and supply of pre-lithiated anode materials, including silicon and graphite, designed for battery manufacturers. These materials are engineered to increase the energy density and cycle life of batteries, directly addressing key limitations in current energy storage technology. By increasing energy density, batteries can be made smaller and lighter or store more energy in the same size, a critical factor for applications like electric vehicles and consumer electronics. Eonix's proprietary, low-cost pre-lithiation technology is designed to be a drop-in solution, allowing for seamless integration into existing battery manufacturing lines without requiring significant changes to established processes.

The company's business model is centered on supplying these advanced materials to cell manufacturers, positioning itself as a key component provider in the battery supply chain. It targets the electric vehicle, consumer electronics, and defense markets. In 2024, Eonix secured $12 million in a Series A funding round led by Sundt AS, with participation from other investors including Coatue, to scale its production capabilities from pilot to industrial levels.
