Ten-Nine Technologies is scaling production of TENIX, a cathode additive designed to reduce degradation in rechargeable batteries, including those used in electric vehicles (EVs).
TENIX is blended into cathode material during battery manufacturing at approximately 0.5 to 2% of the cathode’s weight. The company says the additive can be incorporated into existing cathode production lines without requiring new manufacturing equipment or a battery redesign.
According to Ten-Nine, third-party testing showed more than 75% additional charge-discharge cycles in batteries using the additive. The company also reports a 10% reduction in internal resistance, which can reduce energy losses as heat and improve charging performance.
Ten-Nine says TENIX can reduce battery heat generation by approximately 40% over the battery’s lifetime. Lower heat generation could reduce thermal stress as cells age and place less demand on battery thermal-management systems.
The technology is also being developed for manganese-rich cathodes, which use less nickel and cobalt than many conventional EV battery chemistries. Manganese-rich materials can offer cost and supply-chain advantages but have historically faced challenges with cycle life.
Ten-Nine currently has production capacity of 100 tons of TENIX, which the company estimates is sufficient to treat approximately 50,000 to 200,000 typical EV battery packs depending on additive loading.
The company is conducting evaluation trials with battery manufacturers that collectively represent more than half of global battery production volume and is accepting orders for 2026–27 delivery from its production facility in Tulsa, Oklahoma.
TENIX can also be used in batteries for energy storage, industrial equipment, and other applications.
