Conamix

Conamix is an Ithaca, New York materials company commercializing low-cost, high-energy lithium-sulfur battery technology for the lithium-ion battery market. It develops cathode active materials, proprietary electrolytes and water-based cathode processing, and sells the resulting materials and cell engineering into drone, micromobility and electric vehicle applications. Its chemistry is cobalt-free and avoids constrained supply chains, with reported energy densities above 400 Wh/kg and 80% charge in under 20 minutes. Founded in 2014, the company builds on foundational technology exclusively licensed from Cornell, Stanford, Berkeley and Waterloo.

A whole-stack approach to lithium-sulfur — cathode active material, electrolyte, and water-based electrode processing engineered together — that reaches high energy density and fast charge without cobalt or other scarce, supply-constrained materials.
