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.

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.
Charge-Control Technology
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
1.
Candidate Generation
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.
2.
Recipe Testing
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.
3.
Repeatability Cycling
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.
4.
Customer Validation
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.
Third-Party Validation
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

Iontra Solutions & Services
The Iontra difference:
working with you.
Our underlying technology is the proprietary Iontra Charge-Control Algorithm, which maintains battery health while greatly enhancing performance. Once you’ve seen it work, it’s hard to imagine charging any other way.
Our Commitment to you
When it comes to big leaps forward, we know that proof is paramount. So we provide specific use case testing and analysis to generate customized Charge-Control, hardware you can test at your facilities with our fourth-generation cycling platforms, and services you need to implement Iontra’s technology into battery-powered products of any size.
On-Site Validation at Your Facility
Seeing is believing. After we have tested your cells and proven what Iontra Charge-Control technology can do for you, we’ll send a cycler so you can observe it for yourself. You will be able cycle cells with your current methodology and with Iontra charging. The result: immediate (and remarkable) improvements in charge speed, cycle life, and other factors. Cycle after cycle.
Battery Characterization and Cycling Services
Send us some of your batteries. We will cycle them targeting your performance goals and send you a full report containing all electrochemical data from the most optimized charging algorithm. Based on cycling data and a physical tear down of your batteries, we demonstrate specific performance improvements for your batteries charged with Iontra technology.
Product Integration Services
Iontra’s proprietary algorithm, licensed and coded with the Charge-Control Recipes, is flashed on an application-specific MCU. This Iontra-enhanced chip delivers your defined improvements to the life cycle, charge speed, capacity utilization cold weather performance, and safety of rechargeable batteries.
Currently we are using commercial MCUs for product integration, we’re also developing our own cost- and performance-optimized battery charger MCU for your products to redefine “best-in-class” performance.
Improved performance at any scale.
There has never been more demand for high-performance lithium batteries. And at every scale – from cars and trucks to hearing aids and headphones. And Iontra is working to bring you solutions, affordably without any performance compromise.
