Why Is Lithium Battery Recycling Becoming Increasingly Important?

Building a high-efficiency shredding line × Fulfilling ESG sustainability goals

With the growing demand for electric vehicles, smartphones, laptops, and energy storage systems, lithium batteries have become an integral part of daily life. However, when these batteries reach end-of-life and are not properly handled, they pose risks such as fire, toxic emissions, and the loss of valuable resources.

This article outlines the full lithium battery recycling process, highlights the key technical stages, and demonstrates how advanced equipment can ensure safety, efficiency, and sustainability.

From Waste to Resource: The Full Life Cycle of Lithium Battery Recycling

Pre-Treatment & Safety Protocols

The lithium battery recycling process begins with strict pre-treatment and classification:

Minimum Processing Capacity: Clients must handle a minimum of 500 kg of material for efficient system operation; 1 ton per hour (TPH) would be the optimal choice.
Safety Pre-Process: Before any mechanical handling, batteries require dedicated pre-treatment, including salt water soaking for 7-10 days for full discharge, followed by another 7-10 days of stacking to fully dry.
Classification: Batteries are sorted by chemistry (e.g., NMC, LFP) and shape (cylindrical, pouch, prismatic).Accurate sorting is vital to prevent cross-chemistry hazards during shredding.
Discharging & Disassembly: Protective shells and control boards are removed. Proper discharge is essential to prevent thermal reactions in later stages. Safety zones must include grounding and emergency shut-off systems

The YH Integrated Mechanical Separation System

Yung Hsing’s automated recycling line is designed for seamless, high-safety material separation, integrating crushing, screening, and metal recovery in one efficient process:

Primary Shredding & Safety:

Automatic feeding is linked to the Nitrogen-protected quad-shaft shredder.
Equipment Safety Features: Our system includes explosion-proof designs, a nitrogen-linked safety system.

2. Fine Crushing & Iron Removal:

The material then proceeds through a low-noise hammer mill with sound insulation.
A plug-in magnetic separator and drawer-type iron remover are used to efficiently extract ferrous metals.

Separation & Collection:

Rectangular Screening Machine removes carbon powder and fine impurities.
Gravity separation and final magnetic separation are applied to further sort remaining ferrous and non-ferrous contaminants.
Final Recovered Materials: The process yields high-value material streams, including carbon powder, aluminum foil, copper foil, and plastic film.

Emission Control & Downstream Efficiency:

Dust and Gas Control: The entire system utilizes sealed conveying systems, bag-house dust collectors, and integrated activated carbon scrubbers to filter hazardous gases and fine dust.
Custom Planning: Yung Hsing provides full consultation on whether an activated carbon scrubber is necessary based on your regional compliance requirements.

Storage hoppers enhance downstream efficiency.
