Lithium Battery Electrode Recycling
Lithium Battery Cathode Sheet Crushing & Recycling Line
A configurable mechanical recycling system for separating cathode active material from aluminum foil in lithium-ion battery cathode sheet production scrap. The line integrates controlled feeding, crushing, delamination, screening, classification and dust collection into one coordinated process. Designed for NMC, LFP and other prepared cathode-sheet materials, with equipment selection adjusted to coating condition, foil thickness, feed size, required capacity and target recovered fractions. Final configuration is confirmed after reviewing your material photos, chemistry, condition, capacity and target outputs.
01 / Production line overview
Recover Cathode Powder and Aluminum from Electrode-Sheet Scrap
Prepared cathode-sheet feedstock, not complete battery packs or energized cells.
Cathode sheet recycling requires controlled liberation of the coated active material from thin aluminum foil without turning the entire feed into an unnecessarily mixed fine fraction. BREM configures the line around the actual electrode-sheet condition, coating adhesion, chemistry and required output quality.
The system is designed for prepared lithium-ion cathode sheet scrap generated during battery and electrode manufacturing, including edge trim, rejected sheets and coated aluminum foil. Material passes through staged size reduction and delamination, followed by screening and air/gravity classification to separate active-material-rich powder from aluminum-rich fractions.
Unlike a complete battery crushing line, this process starts with electrode-sheet material rather than energized cells or battery packs. The equipment configuration therefore focuses on efficient coating liberation, powder collection, foil recovery, dust containment and stable continuous operation.
The final line can be configured as a compact cathode-sheet recycling cell or integrated into a larger battery-material recycling plant.
01 — Feedstock-Specific Configuration: Configured around cathode chemistry, coating condition, foil thickness, moisture, dimensions and contamination level.
02 — Staged Material Liberation: Multiple crushing and delamination stages reduce excessive aluminum pulverization while releasing the coated cathode material.
03 — Powder / Aluminum Separation: Screening and aerodynamic or gravity classification separate cathode powder from aluminum-rich fractions.
04 — Enclosed Dust Control: Negative-pressure transfer and centralized dust collection control fine particulate throughout the processing line.
This page describes a cathode-sheet recycling route. Pack dismantling, module dismantling, cell discharge and electrolyte extraction from whole cells are not standard stages for this line.
02 / Feedstock & Outputs
Prepared Cathode-Sheet Feedstock, Separated Material Fractions
This production line is intended for prepared lithium-ion cathode electrode materials rather than complete battery packs or energized cells. Feedstock condition has a direct effect on equipment selection and final separation performance.
Feedstock
LFP Cathode Sheets
Lithium iron phosphate cathode sheets and related coated aluminum foil scrap from electrode and cell manufacturing. Typical forms: continuous sheet offcuts; rejected coated foil; cut cathode pieces; prepared cathode scrap.
Mixed Prepared Cathode Scrap
Prepared cathode-sheet material with known chemistry and controlled contamination. Mixed feed should be reviewed before final equipment selection.
Outputs
Cathode Active-Material-Rich Powder
A fine powder fraction containing the liberated cathode coating material recovered from the aluminum foil substrate. Final composition depends on feed chemistry, coating formulation and process settings.
Recovered Aluminum Foil Fraction
An aluminum-rich fraction separated after coating liberation and classification, suitable for downstream refining or aluminum recycling according to the required project specification.
Fine Collected Cathode Powder
Fine particulate captured from enclosed process air and dust-collection points and managed as part of the recovered powder stream where the material specification permits.
Feedstock should be identified by chemistry and supplied in a condition suitable for mechanical processing. Free liquid electrolyte, high residual solvent, unknown hazardous contamination or complete energized cells require separate engineering review and must not be assumed to be standard cathode-sheet feed. Output purity, particle-size distribution and residual coating on aluminum are material-dependent and should be confirmed through sample testing before final performance commitments are issued.
03 / Complete Production Line & Process Overview
From Cathode Sheet Scrap to Separated Powder and Aluminum Fractions
The line combines staged mechanical liberation, particle-size control, material classification and centralized dust handling. The exact number of machines and process stages is adjusted to the cathode-sheet condition and target outputs.
Process Stages
The line combines staged mechanical liberation, particle-size control, material classification and centralized dust handling.
Controlled Feeding
Prepared cathode sheets are introduced at a controlled rate to stabilize downstream loading and reduce sudden material surges. Feed size and form determine whether pre-cutting is required.
Primary Size Reduction
Large sheets or bundled scrap are reduced to a manageable size for stable downstream processing while avoiding unnecessary generation of ultra-fine aluminum.
Secondary Crushing & Delamination
Mechanical impact and shear forces further break the electrode material and promote separation of cathode coating from the aluminum foil surface.
Fine Liberation
Material requiring additional coating release enters a controlled fine-grinding stage. The objective is to improve liberation while maintaining a separable aluminum-rich fraction.
Screening & Particle Classification
Vibratory screening separates material by particle size, removing liberated fine cathode powder and directing larger aluminum-bearing fractions to the next separation stage or recirculation.
Air / Gravity Separation
Differences in particle density, shape and aerodynamic behavior are used to separate remaining light or foil-rich material from fine active-material-rich fractions.
Cathode Powder Collection
Recovered powder fractions are collected through enclosed discharge points for downstream storage, sampling or further metallurgical processing.
Aluminum-Rich Fraction Recovery
Separated aluminum foil and aluminum-rich particles are discharged as an independent recovered fraction for downstream aluminum recycling or additional cleaning.
Dust & Exhaust Collection
Process points operate under controlled negative pressure. Fine airborne particles are captured by the centralized dust-collection system to improve housekeeping and material containment.
Recovered Material Output
The line continuously produces separated cathode powder and aluminum-rich fractions. Final product specifications are validated against the customer's feedstock and downstream requirements.
Process order may be adjusted after material testing. Some feedstocks can use fewer stages, while strongly bonded coatings or irregular scrap may require additional liberation or recirculation.
04 / Main Equipment Configuration
Core Equipment Selected Around Liberation and Separation Requirements
The equipment list is configured according to cathode-sheet dimensions, coating adhesion, chemistry, required capacity, target powder fineness and aluminum recovery requirements.
Crushing
Fine Liberation
Classification
Separation
Dust Collection
Conveyors, feeders, induced-draft components, pipework, cyclone/pre-collection modules, discharge systems, electrical controls and structural platforms are engineered as part of the complete line even where they are not represented by a standalone Product post. A double-shaft shredder may be added when feedstock regularly arrives as large continuous sheet bundles, compacted sheet scrap or oversized pieces.
05 / Technical Parameters

Capacity is affected by sheet thickness, dimensions, coating loading, binder condition, moisture, contamination level, required powder particle size and the number of liberation/separation stages. Final powder size and aluminum residual coating are material- and process-dependent and confirmed by sample testing. Do not present a fixed purity or recovery percentage unless verified by project testing or approved internal engineering data.
06 / Output Quality
Material Fractions Designed for Downstream Recovery
The line is configured to maximize useful separation between cathode active material and aluminum while maintaining stable collection of fine powder. Final quality targets should be defined according to the customer's downstream refining or recycling route.
Cathode Active-Material-Rich Powder
Liberated cathode coating recovered as a fine powder fraction. Chemistry follows the incoming cathode material, while particle-size distribution and aluminum carryover depend on feed condition and process settings.
- Particle Size
- Material- and project-dependent
- Composition
- Material-dependent; confirmed by sample test
- Recovery Performance
- Confirmed after material testing
- Downstream Use
- Downstream refining or cathode-material recovery routes defined by the project specification.
Recovered Aluminum Foil Fraction
Separated aluminum-rich foil and particles with most of the cathode coating mechanically removed. Residual coating is evaluated according to the customer's downstream aluminum-recycling requirement.
- Composition
- Aluminum residual coating is material- and process-dependent
- Recovery Performance
- Confirmed by sample test
- Downstream Use
- Aluminum recycling or additional cleaning according to project requirements.
Fine Collected Cathode Powder
Fine material captured from process-air collection points. Depending on the feedstock and quality specification, this fraction can be combined with the main cathode powder stream or handled separately.
- Particle Size
- Fine fraction
- Downstream Use
- Managed with the main cathode powder stream or handled separately where the specification requires.
For commercial projects, BREM should confirm the target metrics before contract commitment, including particle-size range, aluminum content in the powder fraction, residual coating on recovered aluminum and acceptable material loss.
07 / Safety Engineering
Safety Controls for Fine Powder, Moving Equipment and Process Stability
Cathode-sheet recycling removes the high-energy risks associated with processing complete energized cells, but fine particulate, mechanical equipment and possible residual process chemicals still require engineered controls.
Controlled Feeding
Stable metering prevents overloads and reduces sudden accumulation inside crushing and separation equipment.
Temperature Monitoring
Key processing points can be equipped with temperature monitoring to identify abnormal friction, bearing conditions or unexpected heat rise.
Negative-Pressure Enclosure
Crushing, screening and powder-transfer points are enclosed and maintained under negative pressure to limit fugitive fine particulate.
Electrical Grounding & Static Control
Electrical grounding and appropriate conductive connections reduce static accumulation in powder-handling and ducting systems.
Fire / Explosion Protection Provision
Protection strategy is selected according to dust characteristics, feedstock condition, local code and final process design. Required isolation, suppression, venting or inerting measures must be determined during engineering review rather than assumed as one universal configuration.
PLC Interlocks
Equipment startup, shutdown, overload protection, fault alarms and upstream/downstream interlocks coordinate the complete line and reduce unsafe operation during abnormal conditions.
Cathode-sheet feed must be screened for free liquid electrolyte, significant residual solvent, foreign metal and other incompatible contaminants before processing. Materials outside the approved feed specification require separate review.
08 / Environmental Control
Enclosed Material Handling and Centralized Fine-Dust Collection
Environmental control is integrated into the production line rather than treated as a separate afterthought. The main objective is to keep cathode powder contained, collect airborne fines and maintain a clean, controllable processing environment.
Dust Collection
Pickup points are arranged around crushing, screening, transfer and discharge positions. Fine particulate is conveyed to a centralized pulse-jet baghouse or project-specific collection system.
Enclosed Transfer
Covered conveyors, sealed connections and negative-pressure ducting reduce fugitive powder during movement between process stages.
Exhaust Purification
Where feed condition or local regulation requires additional exhaust treatment, activated-carbon adsorption, scrubbing or other purification modules can be integrated after engineering review.
Collected Material Management
Recovered fine powder and filter residues are discharged through controlled collection points to support material accounting, housekeeping and downstream handling.
The required exhaust-treatment train depends on feedstock contamination, residual solvent/VOC condition, local emission limits and the final process configuration. Do not show every purification machine as mandatory for a dry, clean cathode-sheet project.
09 / Real Project Case
Cathode Sheet Recycling Project Configuration
BREM configures cathode-sheet recycling projects around the customer's actual material rather than applying one fixed machine list to every plant.
Representative Cathode-Sheet Recycling Configuration
A typical project starts with review of cathode chemistry, sheet size, coating condition, aluminum foil thickness, moisture and contamination. Based on the material test, the crushing and delamination stages are adjusted to release the cathode coating while maintaining a recoverable aluminum-rich fraction. Screening and air/gravity classification are then tuned to the required powder size and downstream quality target. The complete delivery scope can include material feeding, crushing, fine liberation, screening, classification, powder collection, dust control, electrical control, platforms, conveying and commissioning support.

10 / FAQ
Cathode Sheet Recycling Line FAQ
Resolve feedstock, process-route and configuration questions before the engineering enquiry.
What cathode materials can this line process?
The line is designed for prepared lithium-ion cathode electrode materials such as NMC and LFP coated aluminum foil, cathode edge trim, rejected cathode sheets and similar production scrap. Material chemistry and contamination should be confirmed before final equipment selection.
Can the line process complete lithium-ion cells or battery modules?
Not as the standard feed. This line is designed for prepared cathode-sheet material. Complete cells, modules and packs require separate discharging, dismantling and battery-processing stages before electrode material can enter a cathode-sheet recycling process.
Do NMC and LFP cathode sheets use exactly the same settings?
The same basic process concept can be used, but operating parameters and equipment settings may differ because coating properties, binder behavior, sheet thickness and target powder quality are different. Mixed chemistries should be discussed before processing.
What are the main recovered materials?
The primary recovered streams are cathode active-material-rich powder and an aluminum-rich foil/particle fraction. Fine powder captured by the dust-collection system can also be managed as a separate recovered stream where the specification allows.
How clean will the recovered aluminum be?
Residual coating on aluminum depends on the original cathode sheet, coating adhesion, liberation intensity and separation settings. BREM recommends sample testing when the project has a defined aluminum cleanliness target.
What determines the final powder particle size?
Particle size is influenced by the crushing and pulverizing configuration, screen specification, recirculation strategy and the customer's downstream process. The target range should be defined before final equipment selection.
Is dust collection included in the complete line?
Yes. Enclosed transfer and negative-pressure dust collection should be engineered as part of the complete cathode-sheet recycling system because the process generates fine active-material powder.
What information is required for a technical proposal?
Please provide cathode chemistry, material photos or video, sheet dimensions, approximate foil/coating condition, moisture or residual solvent condition, required capacity, operating hours, target recovered products, project location and any required output-quality limits.
