Single point of failure
Roughly three-quarters of the world's nickel refining is concentrated in one country, leaving the global battery supply chain dependent on a single source for Class 1 nickel.
Technology
Battery-grade nickel without the autoclave
BANIQL's BEST™ process selectively extracts nickel at near-ambient temperature and atmospheric pressure — unlike HPAL's high-temperature, high-pressure autoclaves. It is an independent, non-HPAL route to Class 1 nickel, producing clean, recyclable by-products instead of toxic tailings.

The problem
The Class 1 nickel supply chain has a single point of failure
Battery-grade nickel is concentrated, energy-intensive to produce, and dominated by heat- and pressure-heavy incumbents that leave toxic waste behind.
Heat- and pressure-intensive incumbents
HPAL relies on high-temperature, high-pressure autoclaves — energy-hungry, capital-heavy, and operationally demanding to run safely.
Toxic, unmanaged waste
Conventional routes generate large volumes of acidic tailings and toxic by-products that require costly long-term containment.
The product chain
From nickel ore to the battery cell
BANIQL delivers MHP, battery-grade nickel sulfate, and Class 1 nickel metal — feeding cathode and cell manufacturing for EVs, and the superalloys behind spacecraft, jet engines, and the gas turbines powering AI data centers.
- 01
Nickel ore
Lateritic nickel ore secured under a long-term supply MOU.
- 02
MHP
Mixed hydroxide precipitate — an intermediate battery feedstock concentrating nickel for refining.
- 03
Nickel sulfate
Battery-grade nickel sulfate, the precursor input for cathode active material.
- 04
Cathode → cell
Refined nickel units flow into cathode and cell manufacturing — with Class 1 metal also serving aerospace and energy superalloys.
Process outcomes
Lighter footprint than atmospheric leaching and HPAL
Indicative, outcome-level comparison indexed to HPAL = 100 (lower is better), against atmospheric leaching and High Pressure Acid Leaching — driven by near-ambient operating conditions.
Energy intensity
indexed to HPAL = 100 — lower is better
Carbon footprint
indexed to HPAL = 100 — lower is better
Solid waste — BANIQL BEST™
Recyclable
Clean, recyclable solid by-products — agricultural fertilizer and magnesium products — sold rather than stored as tailings.
Solid waste — Atmospheric leaching
High volume
Large volumes of residue that must be neutralized to mitigate environmental damage.
Solid waste — HPAL
High volume
Large volumes of acidic tailings requiring long-term management.
Roughly 70–80% less energy and around 30× more nickel-selective than HPAL, tripling nickel concentration while operating at near-ambient temperature and atmospheric pressure.
Recyclable by-products
Clean, saleable by-products instead of toxic tailings
The BEST™ process turns what conventional routes discard as hazardous waste into useful materials.
- ✓Agricultural fertilizerSolid residue recovered as ammonium sulfate (~21% N) — a saleable agricultural fertilizer, field-tested growing corn.
- ✓Magnesium productsMagnesium-bearing streams recovered as magnesium hydroxide, Mg(OH)₂ — a saleable secondary revenue stream.
Proven, not theoretical
Validated today, positioned for the Class 1 deficit ahead
With Class 1 nickel projected to flip to structural deficit around 2028–2029 (per IEA, Benchmark Minerals and S&P Global), BANIQL pairs a working process with secured ore supply and validated product.
01
Validated product
Over 1,000 kg of battery-grade MHP produced and validated by potential customers in Korea, Japan, Taiwan, and the US.
02
Pre-pilot operating
TRL 6 process running in Indonesia since 2024 at over 100 kg/day of ore, with long-term ore supply secured under MOU.
03
Commercial pull
A signed, non-binding offtake LOI with a Korean customer — estimated at US$16.5–21M — underpins demand for BANIQL nickel units.
