Flow cell testing today is complex, slow, and material-intensive:

• Cell cycling and lifetime testing can take days to months or longer

• Electrolyte volumes >10 mL in even the smallest test fixtures require gram-scale mass of proprietary material (a major issue at R&D scale)

• Test apparati are large, expensive, and often clunky to run in parallel

• Critical experiments are challenging to iterate and statistically validate due to these time, material, and space constraints

This slows R&D and directly delays getting new battery technology to market.

Researchers, technologists, and lean R&D teams working on:

• Flow battery and flow cell cycling, lifetime, and output characteristics

• Novel / proprietary electrolyte chemistries, formulations, and their kinetics

• Comparative membrane, separator, and materials testing
  

Especially useful for those in:

• Startups & early-stage tech development

• Academic labs

• “Skunk Works” style R&D teams

• Government R&D programs
  

• Flow cell and flow battery innovations are a combinatorial problem—you need to test a wide range of materials and conditions to find breakthroughs.

• But current tools force you to test one or two test conditions at a time, with long experimental timeframes, and material and cost bottlenecks.

• The Redoxino™ Test System makes parallel, fast, resource-efficient testing possible—for controls, iteration, and real science.
  

This accelerates your technology learning rate—and your path to commercialization.

Most rely on:

• Legacy flow cell stack architectures: bolts, torque wrenches, too many parts, lots of membrane, patience, and a little luck

• External peristaltic pumps: larger and more expensive than they should be

• Glove boxes for inert gas environment: bulky, expensive, and time consuming to maintain

• DIY setups: appended together with off-the-shelf parts, requiring gloveboxes, peristaltic pumps, and lab-specific custom work
  

Typical experimental setups take up ~1-2 m² of footprint (bench/glovebox space) per test and cost >$20,000.

• Many solutions re-use legacy form factors, fixtures, and design features

• It’s non-trivial to integrate all components (flow, electrical, chemical, electrochemical, sensors, gas handling) into one low-cost, user-friendly unit

• Additive manufacturing (3D printing) has progressed to the point that critical production-quality parts are now possible to manufacture instantaneously for pennies right where you need them, and we leaned into this

• We designed the Redoxino™ Test System out of necessity—because nothing existed that met our needs as researchers

• Our deep background in chemistry, liquid handling, electrochemistry, instrumentation helped us reimagine what was possible

• The Redoxino™ Test System helps Li-ion alternatives catch up faster

• Enables statistically significant and parallelized testing for faster iteration

• Potential to increase R&D throughput by orders of magnitude
  
  

Think of it like a PCR machine for flow batteries—turnaround time and scale matter.

• We are hoping to sell complete build kits for ~$3000 (covers NRE, labor, parts)

• We are also continuously updating our open-source design files and build guides so you can fabricate, 3D print, and source parts yourself for a total bill of materials (BoM) of ~$300-500

• Our goal: Build a community of developers, researchers, inventors, and builders solving real problems together to accelerate the adoption of flow batteries and non-lithium energy storage technologies
  

We patented it, but chose to open-source it—because the world needs better tools, faster.
