Your batteries.

Our charging technology.
Unrivaled performance.

Our third-party validated breakthrough Charge Control technology improves battery performance 2x to 4x and your market share - no matter the size, cost, or complexity of your product

We are proud to enable greater sustainability and lowering of carbon footprint for a greener planet.

Revolutionizing battery charging

Conventional Charging vs Iontra

Rechargeable battery cells today suffer from fundamental damage mechanisms during charging such as lithium plating, dendrite growth and SEI growth on the battery’s anode. This is a safety hazard, reduces usable capacity as well as battery life, and limits charge speed. Iontra’s patented sensing and charging technology prevents this cell damage and unleashes your battery’s true performance potential. 

 

CC/CV Charging

Iontra Charging

Charging is no longer a limitation. It’s a competitive advantage.

Iontra delivers longer cycle life, faster charging, safer batteries, and improved cold weather performance for the cells you use today. And we do this while lowering your carbon footprint & helping you meet your sustainability goals.

≤0°C

Charging Capability

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.

how iontra does it

Iontra’s key to faster charging and longer battery life? Advanced signal processing and innovative 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.

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.

Third-Party Validation

Iontra advancements are proven with data and validated by objective industry authorities, including seven (7) reports from UL Solutions (UL), National Renewal Energy Laboratory (NREL), the University of Michigan, and Novonix. All validation reports are available on request.

Validation Reports

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

Novonix

BTS, September 2021

Iontra capability would be highly beneficial to battery chemistries that suffer from dendritic growth such as those based upon lithium and zinc.

University of Michigan

Dasgupta Lab Report, 2018

The message is clear: Iontra improves cycle life for charge rates greater than spec sheet when compared to industry standard CC/CV charging techniques.
