Recovering Critical Elements for a Circular Battery Supply Chain

Recovering critical minerals from used batteries isn’t just about recycling. It restores the life cycle and adds value to these materials. At NavPrakriti, every gram we recover reduces the energy lost in mining, reduces emissions, and saves resources for future generations. Our hydrometallurgical refining for lithium batteries recovers high-purity intermediates and battery-grade lithium carbonate (Li₂CO₃, 99.5%), Cobalt sulphate (CoSO4), and Nickel sulphate (Ni2SO4) from active material concentrates, cathode, and anode residues.

What We Process at Our Battery Metal Recovery Plant

Active material concentrates

from NMC, NCA, LCO, and LFP chemistries

Cathode and anode scrap

from production or decommissioned units

Copper and aluminium foils

recovered during dismantling and discharge phases

Completing the Circle of Clean Energy

Driving a Greener Tomorrow through an Eco-friendly lithium-ion refining process

What you discard as waste might have the potential to be rediscovered. At NavPrakriti, we believe in precision-driven processes. Our Hydrometallurgical Refining Facility is designed for EV battery recycling and material recovery. We can recover up to 98% of critical minerals like nickel, cobalt, and lithium. For metals such as copper and aluminium, we extract them efficiently to make sure the loss is minimal, while separating and repurposing plastics responsibly.

What We Do: Hydrometallurgical refining for lithium batteries

At NavPrakriti, we follow a CPCB and EPR-aligned, multi-step hydrometallurgical refining process for batteries. The process is designed for accuracy, efficiency, and minimizing waste. We monitor each stage through ICP-OES and analysis to ensure chemical integrity and product uniformity before dispatching it to you. We use advanced technology developed in collaboration with CMET, Hyderabad, which helps us minimise material loss and maximise recovery efficiency.

Intake and Registration

After collecting the used batteries, we document each one and assign a unique identification number for better traceability.

Safe Opening

Since the batteries often contain hazardous materials, the packs are opened in controlled, de-energized environments with fire and electrostatic protection.

Testing and Data Logging

We test each module and cell for capacity, SoH (State of Health), and voltage. The process involves:

  • Visual and electrical inspection to identify damage or
    leakage
  • OCV and IR testing to check voltage and internal
    resistance
  • Visual and electrical inspection to identify damage or
    leakage
  • OCV and IR testing to check voltage and internal
    resistance
Grading and Sorting

We then categorize the cells as A, B, or C grade based
on test results.

  • Grade A: Over 85% SoH, suitable for premium ESS
    applications can perform up to 12–24 months
  • Grade B: 70–85% SoH for stationary and moderate-duty
    systems offer high performance up to
Cell Matching and Balancing

Cells with similar performance characteristics are grouped together to ensure stable operation.

Our Outputs and By-Products

Our EV battery recycling and material recovery produces:

  • Sulphates and Carbonates of Nickel, Cobalt, and Manganese, which can be used for cathode production
  • The lithium-ion battery material recovery process refines lithium carbonate(Li₂CO₃) to 99.5% purity.

Quality Control and Certification at NavPrakriti

At NavPrakriti, we make sure our every product’s output is verified through standardized Certificates of Analysis (CoA) and material traceability records. This is an essential part for PIBOs (Producers, Importers, and Brand Owners) who want to comply with EPR. We also have a strict quality framework that ensures that every shipment meets both domestic and international standards for purity, safety, and consistency.

  • Each batch is analyzed within a 3–5 day window to confirm the chemical composition, metal concentration, and moisture levels.
  • Once assays are validated, settlements are processed within 7–10 working days.
  • Our in-house laboratory employs Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) for trace metal quantification, X-ray Fluorescence (XRF) for compositional profiling, and gravimetric validation for cross-verifying purity and yield.

Why Choose NavPrakriti

Metal recovery from used lithium batteries requires an advanced facility, high precision, and a controlled environment.

Here’s why you should choose our battery material recovery services:

Promoting Circular Economy

Battery refurbishment is a key step in building India’s circular battery ecosystem. It closes the loop tween manufacturing, use, and recycling, ensuring thatmaterials stay in motion, waste is minimized, and sustainability becomes an achievable standard.

Lower Emissions Footprint

By extending the life of existing batteries instead of manufacturing new ones, refurbishment reduces overall lifecycle carbon emissions by up to 60%, inimizing the environmental impact of mining, refining, and logistics in the global battery supply chain.

Affordable Energy Storage

Refurbished batteries provide a cost-effective lternative to new lithium-ion packs, reducing total energy storage costs by up to 50%. So, whether it’s a refurbished laptop battery or an industrial ESS, avPrakriti helps make clean energy more accessible.

Reduced Resource Extraction

Repurposing existing cells helps delay the demand for virgin raw materials such as lithium, cobalt, and nickel. By recovering more value from what already exists, NavPrakriti reduces the pressure on global mining and supports responsible material use. This is a sustainable approach to refurbish lithium ion battery systems for reuse.

Doing our part for a cleaner planet.

Transitioning to a sustainable future requires the responsible use of our valuable and finite resources.

Through our focus on battery recycling, we aim to minimize environmental impact and foster a sustainable future, keeping our people and planet in mind. This approach allows us to keep the well-being of both nature and communities at the forefront of our operations.

Through our efforts, we seek to drive meaningful change and create a world where future generations can thrive in harmony with their environment. It all starts with NavPrakriti.
