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.
Our process — developed at the University of Houston — recovers spent LFP cathode-active material by directly repairing the LFP rather than breaking it down to intermediate salts. This is direct regeneration — not hydrometallurgy, not pyrometallurgy.
| Elemental balance | Restore oxidized Fe and replenish missing Li |
| Crystal structure | Repair lattice distortion and particle degradation |
| Carbon coating | Restore the damaged conductive carbon layer |
The original particle size and morphology engineered into the starting material — all the engineering work the original cathode synthesis did. We do not destroy the LFP structure to recover it. We repair it.
Conventional recycling treats spent LFP as a chemical feedstock — strip it down to elements, then re-synthesize cathode material from scratch. We treat spent LFP as a damaged product: repair what cycling broke, and leave the engineering intact.
Dissolves the cathode first, then spends heavily to rebuild value through separation and purification. Output is leached metal salts still requiring downstream re-synthesis.
High-temperature smelter loops. Effective for nickel-, cobalt- and copper-rich streams, but poorly suited to LFP — it destroys the structure and leaves lithium value to costly downstream purification.
Preserves the cathode structure, particle morphology, size, and surface chemistry — the part of the value that took the most energy and money to put there in the first place.
Unlike nickel-cobalt cathodes, LFP's economic value lies mainly in its engineered structure rather than its elemental content. Breaking LFP down destroys that value and forces costly re-synthesis.
| 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. |
The same operator sits at both ends: the pack lands back in the same portfolio. Texas built the largest grid battery fleet in the country, and today essentially all of its spent cathode leaves the state when it is recycled at all — while replacement material is imported back in. Texas should not have to import the materials to keep its own fleet running.
