A next-generation battery material regeneration company. We restore spent lithium-ion cathode material to original performance — using less energy and producing less chemical waste than conventional recycling.
RETTAB Technology specializes in the direct regeneration of lithium-ion battery materials. Using advanced characterization techniques and a clean chemical process developed at the University of Houston, we restore spent cathode material to original performance — without the acids, bases, or high-heat smelting that conventional recycling depends on.
Our focus is lithium iron phosphate (LFP): recovering high-value material from end-of-life packs and manufacturing scrap, and returning it to battery producers as manufacturer-grade cathode active material. The name says it plainly — Rettab is battery reversed, for reversing the traditional lifecycle of energy storage.
The particle is preserved rather than destroyed. Where conventional routes break the cathode down to intermediate salts and resynthesize it, we repair the crystal structure in place — retaining the original particle size and morphology while replenishing deficient elements.
| Domestic supply | US-regenerated cathode material supports the domestic-content position that American cell manufacturers increasingly need to qualify for federal energy-storage credits. |
| Clean chemistry | No acids, bases, or high-heat smelting — a lighter-capital, lower-impact route than hydrometallurgical or pyrometallurgical recycling. |
| Closes the loop | Recovers value from spent LFP that most recyclers skip, because LFP lacks the cobalt and nickel that pay for conventional recovery. |
| Texas-sited | Houston-based, adjacent to the Gulf Coast energy-storage buildout — keeping Texas battery material in Texas. |
