Solving the
toughest problem
in batteries

Conamix is a team of work-hardened battery experts turning sulfur cathodes from the out of reach holy-grail of lithium ion cathodes into a global product with the energy, power and cycle life demanded by the EV revolution.

The lowest cost and highest energy viable cathode material on the periodic table – globally abundant and a by-product of the oil and gas industry.


Making sulfur cathodes work at real commercial performance levels – sulfur by-products reduce performance and drop cycle-life while low density single function materials impact energy and power.


Drop in slurry coatable cathode active from low cost materials.

Completely cobalt and nickel free cathode

Over 25% cost reduction at the cell level in $/kWh


Based on innovations developed at Cornell, Stanford, University of Waterloo, Berkeley Lab and other global research institutions


Conamix is on track to make lithium sulfur work on a global scale by using a ‘stack’ of multi-functional materials that will address the barriers that blocked past efforts. Conamix Sulfur Stack™ includes:

Meta particles with gradient structures that balance the transport of ions and electrons for improved power capability, energy density, and life Bi-functional cathode additives that simultaneously store Li and conduct electrons, replacing expensive and space wasting carbons A new ‘binding’ molecule that spatially constrains the electrochemical reaction storing the energy and thereby extends life Novel electrolyte components that improve the basic efficiency of the electrolyte, providing improved energy density A novel cathode design that enables a new level of safety and energy density
