Problem
Lithium-ion batteries suffer from plating and dendrite growth on the anode during charging, which reduces usable capacity, shortens battery life, and limits charging speed. Conventional charging methods often fail to optimize battery performance, especially in cold temperatures, leading to inefficiencies and safety concerns.
Solution
Iontra has developed Charge-Control technology that prevents dendrite growth and plating on lithium-ion battery anodes, thereby enhancing battery performance. This technology enables faster and safer charging, extends cycle life, and improves cold weather performance. Iontra's charging algorithm uses advanced signal processing and adaptive charge control, custom-engineered for specific product performance goals. The technology makes micro-adjustments to charging, reducing resistance and enabling safe, high-voltage charging across the operating temperature range.
Target Audience
Iontra's technology targets manufacturers of battery-powered devices, ranging from small devices like hearables and wearables to portable devices like smartphones and power tools, and e-mobility applications like EVs and large drones.
