Revolutionizing battery charging
Conventional Charging vs Iontra
Rechargeable battery cells today suffer from the fundamental vulnerability of plating and dendrite growth on the battery’s anode. This reduces usable capacity as well as battery life and limits charge speed. Iontra’s patented technology prevents this cell damage and unleashes today’s battery’s true performance potential.
No Charging Build-up
Charging is no longer a limitation. It’s a competitive advantage.
You decide how best to use the performance advantages provided by Iontra. Improvements to any combination of cycle life, faster charge, cold weather charging, and capacity utilization are possible, while always maintaining superior safety.
Longer Cycle Life
Replacing batteries often? We can increase cycle life by 2x or even 4x. Our customers are amazed how long their batteries retain like-new performance.
Tired of waiting for your batteries to charge? Achieve up to 2-4X faster charging with our solution!
Faster AND Safer charging is now possible with Iontra technology. Our solution makes micro-adjustments to charging, thus reducing resistance, eliminating plating, and enabling safe, high voltage charging across the operating temperature range. This significantly reduces the risk of thermal runaways and other operational risks, keeping your products safer for your customers.
As temperatures drop, so does the capacity and stability of lithium batteries – especially below freezing. Most batteries need to be above 0-10°C before they can charge effectively or risk plating damage. Our technology makes it possible to charge batteries at or below 0°C (proven on packs at -20°C) while keeping the batteries safe and healthy. This is a major step forward for outdoor products such as electric cars, trucks, outdoor battery-operated equipment, and even power tools used at construction sites.
Our technology is battery chemistry agnostic and is designed to maximize the performance of today’s and next gen battery technologies including Li-metal, LiS, Zn, Na-ion, Solid state and others.
how iontra does it
Iontra’s key to faster charging and longer battery life? Advanced signal processing and innovative adaptive Charge-Control.
The Iontra charging algorithm is custom engineered for our customers’ product performance goals. Seamless to the user, the battery safely charges faster and lasts longer. Here’s what we do to make it happen – in a fraction of a second.
Iontra’s proprietary Charge-Control technology gives your products a competitive advantage. We unlock the potential in all batteries for longer life and higher performance, even in extreme cold temperatures
We begin with our experimental process to define boundary conditions beyond the customers’ spec sheet. We generate variations of multiple algorithm parameters, and design experiments to explore a large parameter space.
We evaluate 30-60 different charging recipes, with 1-2 cells per recipe along with controls. We then cycle the cells to 50% of the target cycle life, and examine initial performance data alongside our customer.
Our team cycles replicates of various recipes to 100% of the target cycle life. The conclusion of phases 1-3 generates a final recipe that maximizes performance targets.
Phase 4 involves cycling cells with the final recipe either at the customers' site or in Iontra's headquarters. This produces our final round of statistically relevant new product development data to qualify the recipe for commercial use.
Proven by global industry experts.
Iontra advancements are proven with data and validated by objective industry authorities, including UL Solutions (UL), National Renewal Energy Laboratory (NREL), the University of Michigan, and Novonix. All validation reports are available on request.
Cells cycled at traditional 3C CCCV rates lost 13% [SOH] of the cell capacity, Iontra 3C cells lost [only] 4% [SOH] in the same number of cycles
