TENIX Cathode Additive Reaches Commercial Production in Oklahoma

Ten-Nine Technologies has begun commercial-scale manufacturing of TENIX, a cathode additive aimed at curbing the chemical breakdown that causes battery performance to fade over time. The company is ramping up output at its Oklahoma facility.

TENIX is blended into cathode material during cell manufacturing at just 0.5–2% of the cathode’s weight. In practical terms, that translates to roughly 0.5–2 kg of additive for every 100 kg of cathode material processed. The small dosage is intended to slow degradation without altering the core chemistry of the cathode.

By moving TENIX from lab-scale to commercial production, Ten-Nine Technologies is positioning the additive as a drop-in option for battery makers looking to extend cycle life. The Oklahoma site now serves as the company’s production base for the material.

Questions remain about how widely the additive will be adopted across the industry, but the shift to commercial output marks a step beyond research-stage development for the company.
