Ten-Nine Technologies’ TENIX cathode additive delivers over 75% more charge-discharge cycles, extending typical EV battery life from 150,000 to more than 265,000 miles while reducing internal resistance by 10% and lifetime heat output by ~40%.

Over 75% more charge-discharge cycles — that is the performance gain delivered by TENIX, a patented cathode additive developed by Oklahoma-based Ten-Nine Technologies. The material stabilizes lithium-ion battery chemistry during operation, directly countering degradation mechanisms that normally limit lifespan and range.
TENIX is blended into cathode material during standard manufacturing, occupying just 0.5–2% of total cathode weight — approximately 0.5–2 kilograms per 100 kilograms of cathode, matching the cathode mass found in a typical electric vehicle battery pack. Its integration requires no new equipment or redesign of existing battery architecture. At current production capacity of 100 tons annually, Ten-Nine Technologies can supply enough TENIX to treat between 50,000 and 200,000 typical EV battery packs.
“Just like people, batteries age. Products of chemical decomposition build up during use, limiting a battery’s performance and lifetime, and until now that’s just been treated as an unavoidable cost of doing business,” said Paige Johnson, Founder and CEO of Ten-Nine Technologies. “I’m a chemist so I wanted to fix that at the source rather than build a whole new battery to work around it. TENIX has a unique surface chemistry that disrupts that aging process, giving batteries more power and significantly longer life. I started this company in the back of a warehouse in Tulsa with $100,000 and four grams of material in a flask. I never imagined we’d end up here, but I always believed that if the chemistry was right, it would matter to a lot of people’s lives. That’s still what gets me up in the morning.”
In third-party testing, TENIX extended a typical EV battery’s usable life from a 150,000-mile warranty baseline to more than 265,000 miles. That increase corresponds to over 75% more charge-discharge cycles. The additive also reduces internal resistance by 10%, enabling faster charging and less energy loss as heat. According to a company press release, these improvements translate into roughly 40% lower cost per kilowatt-hour delivered over the battery’s full operational lifetime.
TENIX cuts a battery’s heat output by approximately 40% over its lifetime — a feature gaining urgency as AI-driven data centers demand increasingly intensive duty cycles from backup battery systems. This technical momentum coincides with a broader industry pivot toward manganese-rich cathodes: chemistries that are cheaper, more abundant, and less geopolitically concentrated than cobalt- and nickel-heavy alternatives currently dominant in EV batteries.
Manganese is mined across Africa, South America, and Southeast Asia — unlike cobalt and nickel, which are heavily concentrated in a small number of countries. That geographic diversification strengthens supply chain resilience for battery manufacturers and policymakers alike. Historically, manganese-rich cathodes have suffered from poor cycle life — precisely the limitation TENIX is engineered to overcome. Ten-Nine Technologies projects that widespread adoption could reshape the global cathode supply chain as profoundly as lithium iron phosphate (LFP) did two decades ago.
