ReVoltX

Lithium-ion battery recycling · Alwar, Rajasthan

Closing India’s Battery Loop.

ReVoltX recovers cobalt, nickel, manganese and lithium from end-of-life lithium-ion batteries and returns them as battery-grade salts, through Dual MetallurgyX, a process developed entirely in-house.

Process: battery packs are shredded into black mass, refined by Dual MetallurgyX, and recovered as cobalt sulphate, nickel sulphate, manganese sulphate and lithium carbonate.

The problem

The Metals India Needs Are Already Here.

India’s shift to electric mobility and stored energy will retire a growing volume of lithium-ion batteries every year. Today, most of those reaching end of life are dismantled informally or leave the country as low-value scrap, while Indian cell and cathode manufacturers import the very lithium, cobalt, nickel and manganese they contain.

The Battery Waste Management Rules, 2022 have made producers accountable for what happens to their batteries. What the country needs next is recycling capacity that meets that standard and returns material fit for new cells. ReVoltX is being built to be part of that capacity.

What we do

From End-of-Life Cell to Battery-Grade Salt

01

Collect

Cells, modules and packs are received from OEMs, manufacturers and collectors with full documentation, logged lot by lot, and safely discharged.

02

Shred & Separate

Mechanical processing separates copper, aluminium, steel and plastics for their own recycling routes, leaving black mass, the concentrate that carries the critical metals.

03

Dual MetallurgyX

Our in-house hydrometallurgical process recovers lithium first, then leaches and separates cobalt, nickel and manganese into purified streams.

04

Battery-Grade Output

Each stream is crystallised to battery grade as CoSO₄, NiSO₄, MnSO₄ and Li₂CO₃, for India’s cathode and cell manufacturers.

Why ReVoltX

Why ReVoltX

Process Ownership

Dual MetallurgyX was developed and validated in our own laboratory before any plant equipment was specified. As battery chemistries evolve, we adapt the process ourselves.

Compliance From Day One

Our Consent to Establish from the Rajasthan State Pollution Control Board is in place, and CPCB R4 recycler registration is in progress. Continuous emissions monitoring is designed into the plant.

Rooted in Alwar

Located in Matsya Industrial Area Extension, within reach of Delhi NCR’s EV and electronics base, and led by partners with decades of manufacturing experience.

Our story

Built with Patience, for the Long Term.

Three of us spent decades building manufacturing businesses in PVC and cables. The fourth came from engineering and consulting. We came together around one conviction: the materials that will power India’s coming decades should be recovered, refined and reused here, responsibly.

What we saw

A growing stream of spent lithium-ion batteries from vehicles, electronics and energy storage, with most of its value lost to informal recycling or exported, while the same metals were imported back.

Why now

The Battery Waste Management Rules, 2022 and Extended Producer Responsibility created a clear need for recyclers that are both compliant and technically capable. That need will grow with every year of EV adoption.

What we are building

An integrated plant in Alwar that takes a battery from shredding to battery-grade salts under one roof, powered by Dual MetallurgyX.

How we are building it

Self-funded and deliberate. Every stage was proven at the bench before it was scaled, so that what we build is understood completely and can grow with confidence.

Where we are headed

To become a trusted part of India’s critical-minerals supply chain, keeping the country’s battery metals in circulation at home and contributing, steadily, to a more self-reliant and lower-carbon India.

Mission

To recover critical metals from India’s end-of-life lithium-ion batteries safely, responsibly and to battery grade, with care for the environment, for the people who do the work, and for the community around us.

Vision

An India where the metals in every battery are recovered and used again, and where that capability is built at home.

Technology & process

Dual MetallurgyX

A mechanical front end followed by a hydrometallurgical train, developed in-house. Described here at the level of detail we share publicly.

1

Pre-Processing

Cells and packs are discharged, dismantled and shredded under controlled conditions. Screening and separation isolate black mass from copper, aluminium, steel and plastics, which move to dedicated recycling routes.

Black massCu foilAl foilSteelPlastics
2

Lithium Recovery

Lithium is recovered early in the flowsheet instead of at the end, where it would be diluted across multiple streams. This improves lithium recovery and keeps downstream solutions cleaner.

Out
Li₂CO₃
3

Sulphuric Acid Leach

The remaining black mass is leached in sulphuric acid under controlled reducing conditions, bringing cobalt, nickel and manganese into solution and leaving graphite as a residue.

Out
Pregnant leach solutionGraphite residue
4

Solvent Extraction Train

A multi-stage solvent extraction circuit separates manganese, cobalt and nickel, one metal per circuit, and removes impurities to produce purified single-metal solutions.

Mn solutionCo solutionNi solution
5

Crystallization

Each purified solution is crystallised to a battery-grade sulphate. Hydroxide or carbonate products can be produced from the same streams to customer specification.

Developed In-House

The process is ours end to end, which allows us to adapt it as battery chemistries change.

Proven at the Bench

Each unit operation was developed and documented in our laboratory before it was scaled to plant equipment.

Verified Batch by Batch

Feed, intermediates and final products are analysed in our own laboratory before any batch is released.

Closed Loop RECOVER REFINE REUSE

The idea behind ReVoltX

Designed as a Loop

Metals recovered at ReVoltX go to India’s cathode and cell makers, become new batteries, and return to us at end of life. Each pass through the loop reduces the need for imported and newly mined material.

Environment

Keeping Batteries Out of Informal Recycling

Every battery processed at our plant is one that is not dismantled unsafely. Recovered metals reduce the need for imported and newly mined material.

People

Safety as a Discipline

Controlled discharge before shredding, full PPE on the plant floor, and a written, trained procedure for every hazardous step.

Community

Building Skills in Alwar

We hire and train chemists, engineers and operators from the region for skilled roles in a modern, regulated plant.

Quantified environmental outcomes, including CO₂ avoided and import substitution, will be published once the plant is in operation and the figures can be verified.
