Li-ion (Lithium-ion) battery scrap refers to damaged, end-of-life, or manufacturing-rejected lithium batteries that are no longer suitable for use but still contain valuable materials such as:
Lithium
Cobalt
Nickel
Manganese
Copper & Aluminum foils
Graphite
What Can Be Recycled from Li-ion Battery Scrap?
Component

What Can’t Be Recycled?
Burnt, swollen, or chemically damaged cells
Plastic separators
Expired electrolyte fluid (in large-scale)
BMS (Battery Management System) IC boards (unless e-waste processed separately)
How the Li-ion Battery Recycling Process Works
There are three major recycling methods:
1. Pyrometallurgical Process (Thermal)
Burn batteries in high-temperature furnaces (600–1000°C)
Recover metals from slag (e.g., cobalt, nickel)
Disadvantage: Energy-intensive, releases gases
2. Hydrometallurgical Process (Chemical)
Shred batteries
Use acid leaching + precipitation
Extract lithium, cobalt, nickel with 90%+ purity
Eco-friendly & most used
3. Direct Recovery Method
Separate components mechanically
Restore cathode/anode with minimal chemical usage
Used in R&D & pilot plants

Environmental Benefits of Li-ion Battery Recycling
Impact Area
Benefits
Waste Management
Prevents toxic landfill dumping of lithium and cobalt
Resource Saving
Reduces need for mining rare metals
Energy Saving
Recycling uses up to 70% less energy than mining
Air Pollution
Controlled emissions compared to raw material extraction
Job Creation
Builds green jobs in circular economy sectors
Government Rules for Battery Waste Handling in India (E-Waste 2022)
Extended Producer Responsibility (EPR) – Brands must take back old batteries
Registered recyclers only can process battery waste
Fire-proof packaging required for lithium batteries transport
Must maintain data of incoming scrap and outgoing recycled material
Battery Scrap Collection & Storage Tips
Store in cool, dry place with fire-resistant bins
Sort batteries by chemistry (LFP, NMC, LCO) if possible
Use electrically insulated containers
Avoid puncturing or short-circuiting cells during transport
