Anti-aging EV battery additive that stables range, offers 75% more cycles to see production boost

An Oklahoma-based company is scaling production of its anti-aging battery additive. Called TENIX, the patented cathode additive is developed by Ten-Nine Technologies.Every time batteries charge and discharge, unwanted chemical by-products build up inside them.TENIX stops that aging process at the source. It’s blended directly into a battery’s cathode material during manufacturing – taking up just 0.5–2% of its weight, or roughly 0.5–2kg for every 100kg of cathode, which is about what’s in a typical EV battery pack. Battery additive supply enough to treat between 50,000, 200,000 typical EV battery packs It drops into cathode production lines that manufacturers already run, so adopting it requires no new equipment and no battery redesign. At its current production capacity of 100 tons, Ten-Nine 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.” Battery additive delivered over 75% more charge-discharge cycles In third-party testing, TENIX delivered over 75% more charge-discharge cycles, extending a typical EV battery’s life from a 150,000-mile warranty baseline to more than 265,000 miles. That longer life translates into roughly 40% lower cost per kilowatt-hour delivered over a battery’s lifetime, while 10% lower internal resistance means faster charging and less energy wasted as heat, according to a press release.TENIX can also cut a battery’s heat output by around 40% over its lifetime – a benefit that is becoming increasingly critical as AI-driven data centers push backup batteries harder than ever. This momentum comes as the battery industry is increasingly shifting toward manganese-rich cathodes – a cheaper, more abundant, and more geographically secure alternative to the cobalt- and nickel-heavy chemistries that dominate EV batteries today, as per the release.Ten-Nine Technologies also revealed that the manganese-rich cathodes also offer a far more secure supply chain than the nickel- and cobalt-heavy chemistries they could replace. Manganese is mined widely across Africa, South America, and Southeast Asia, rather than concentrated in a handful of countries, making it far less exposed to the geopolitical pressure points that increasingly worry battery manufacturers and policymakers alike.Manganese-rich cathodes have also long been held back by poor cycle life, exactly the problem TENIX is built to solve. Ten-Nine believes the shift could reshape the global cathode supply chain the way LFP did twenty years ago.Get the latest in engineering, tech, space & science - delivered daily to your inbox.Prabhat, an alumnus of the Indian Institute of Mass Communication, is a tech and defense journalist.
