Generate alkalinity in situ
A bipolar membrane generates hydroxide inside the feed channel, bringing pH control directly into the electro-membrane process.
Resource Recovery Technology
Electrically driven membrane co-precipitation
A more direct, more circular path to battery-metal recovery.
ElectroMCP changes the recovery architecture—not just one separation step. Using low-voltage electricity and bipolar membranes, it generates alkalinity inside the process, removes iron and aluminum impurities first, and then directly co-precipitates nickel, cobalt, and manganese while reducing reliance on alkaline chemicals.

Electrical control at the point of recovery
Generate alkalinity where metal recovery happens.
ElectroMCP uses water and low-voltage electricity to generate hydroxide inside the feed channel, enabling selective impurity removal, composition-preserving NCM recovery, and acid recirculation within one process architecture.
Preserve the NCM composition
After Fe/Al removal, nickel, cobalt, and manganese are co-precipitated in one operation—without separating three metals only to blend them back.
Return acid upstream
Membrane-controlled ion transport creates an acid-rich stream designed for concentration and reuse in upstream sulfuric-acid leaching.

Includes a projected 1,080 kWh/day reduction in treatment energy at a 600 m³/day reference facilityThe 60% reduction is a system target. Facility-scale figures are projections for a 600 m³/day reference case. Actual results depend on feed composition and operating conditions.
A shorter recovery pathway
From repeated chemical processing to electrically controlled recovery.
ElectroMCP turns pH control from an external dosing operation into an electrical input, enabling impurity removal and direct NCM co-precipitation in one feed pathway.
Electrically generated alkalinity
Low-voltage DC power drives bipolar membranes to generate OH⁻ from water directly inside the module.
Impurities removed first
Iron and aluminum are removed within a controlled pH window while nickel, cobalt, and manganese remain in solution.
Composition-preserving NCM recovery
Direct co-precipitation preserves the target NCM composition, reducing the need to separate and recombine individual metals.
Acid recirculation pathway
The acid-rich stream created through membrane-controlled ion transport can be linked to concentration and reuse in upstream leaching.
