Lithium-ion Battery Separator Crusher | Detailed Explanation of Lithium-ion Battery Separator Recycling Solutions

Against the backdrop of the accelerating global energy transition towards clean and low-carbon sources, lithium-ion batteries, as core energy storage units, are widely used in new energy vehicles, energy storage power stations, consumer electronics, and other fields.
With the rapid increase in the number of lithium-ion batteries in use, the recycling and disposal of waste lithium-ion batteries has become an unavoidable and important issue in the new energy industry chain.
In the lithium-ion battery recycling process, the lithium-ion battery separator, as a key non-metallic component, requires efficient crushing and recycling treatment, which directly impacts recycling safety, resource utilization rate, and overall economic benefits.
This article will systematically analyze the necessity of lithium-ion battery separator recycling and focus on introducing the Aceretech GE series lithium-ion battery separator crusher, explaining its core advantages and application value in the field of separator recycling.

Lithium-ion battery separators are usually made of polyethylene (PE) or polypropylene (PP). They are microporous polymer films located between the positive and negative electrodes. Their main functions include:
 Preventing direct contact between the positive and negative electrodes to avoid short circuits
 Allowing lithium ions to pass freely
 Improving battery safety and cycle life
Although the separator accounts for a small proportion in a single battery cell, its total amount is enormous in large-scale retired lithium-ion batteries, and its recycling value and environmental impact cannot be ignored.

Preventing potential pollution spread
Waste lithium-ion batteries contain residual electrolyte and heavy metals, which, if not properly handled, may cause long-term pollution to soil and water sources. If the separator is mixed with other components, it will increase the difficulty of dismantling and subsequent sorting.

Reducing plastic pollution
The separator is essentially a high-performance plastic film that is difficult to degrade naturally. Through professional recycling and crushing treatment, the environmental pressure caused by landfill and incineration can be effectively reduced.

Achieving PE/PP plastic resource regeneration
After crushing, cleaning, and granulation, the separator can be made into recycled plastic granules for the production of plastic products such as pallets, pipes, and building templates. 

Improving overall profitability of lithium-ion battery recycling
In the "disassembly-crushing-separation-purification" process, efficiently separating non-metallic materials such as separator membranes in advance helps to improve the purity and efficiency of lithium, cobalt, and nickel recovery.

* Lightweight and thin texture

The Aceretech GE series lithium battery separator film shredder has become an ideal choice for safe, efficient, and economical recycling in the new energy recycling industry.

A: A typical lithium battery separator film recycling process includes:
Battery disassembly or crushing pretreatment, initial separation of separator film and electrodes, separator film crushing, cleaning, dewatering, drying, and regeneration granulation or classification and utilization.

A: No. The GE series features DC53 high-wear-resistant blades (62–64 HRc) and a high-strength steel plate crushing chamber.
Compared to ordinary blades: it has a longer service life; requires less frequent blade changes; is easier to maintain; and has overall lower maintenance costs in the industry.

A: Yes.
The crushed separator film is processed through shredding, crushing, cleaning, drying, and granulation to produce recycled PE/PP plastic granules, which are used in: plastic pallets/pipes/construction formwork/industrial plastic products, achieving resource recycling.

A: When choosing a manufacturer, it is recommended to focus on:
 Whether they have experience in processing film materials;
 Whether they have case studies in the lithium-ion battery recycling industry;
 Whether the blade type and rotor structure are optimized for separator films;
 After-sales and technical support capabilities;
Aceretech has mature equipment and engineering experience in the field of lithium-ion battery recycling and plastic regeneration.

A: Yes.
The GE series is not only suitable for lithium-ion battery separator films, but can also process: PE/PP films; plastic sheets; packaging films; small hollow plastic products; and has good versatility.
