Problem
Current lithium and critical metal recycling processes rely heavily on chemical reagents and generate significant wastewater, limiting recovery efficiency and environmental sustainability. Only a small fraction of lithium from spent batteries is currently reclaimed, creating supply constraints for clean‑energy technologies.
Solution
Re-Volt employs a proprietary electro‑separation platform that uses an electrical potential across advanced membranes to selectively extract lithium, nickel, cobalt, copper, and other valuable metals from lithium‑ion battery waste and geothermal brines. The process minimizes chemical usage and achieves near‑zero wastewater discharge, delivering higher recovery rates for target metals while removing impurity metals such as iron, aluminum, and zinc. Recovered metal salts are produced at high purity, enabling direct reuse in new battery manufacturing and supporting a closed‑loop circular economy for critical materials.
Target Audience
Primary customers are battery recyclers, lithium‑ion battery manufacturers, and producers of geothermal brine that require efficient, environmentally responsible recovery of lithium and other critical metals.
Features
- Electro‑membrane technology that drives metal separation using precise electrochemical potentials, reducing reliance on harsh chemicals
- Multi‑stage workflow including impurity removal (95‑99% Fe, Al, Zn), electrolytic recovery of Ni and Co (>70% yield), and high‑purity lithium carbonate extraction
- Integrated copper and graphite separation to recover additional valuable battery components
- Near‑zero wastewater generation through closed‑loop water management
- Scalable design applicable to both spent Li‑ion battery streams and geothermal brine sources
