From May 13 to 15, the 18th China International Battery Fair (CIBF 2026) grandly took place at Shenzhen World Exhibition & Convention Center. With the theme "Connect Globally, Empower Green Development, Shape the Future", the event covers an exhibition area of 280,000 square meters.

It has gathered nearly 3,200 leading enterprises from across the global industrial chain and attracted more than 400,000 professional visitors. The exhibition fully encompasses the entire industrial chain, including power batteries, energy storage batteries, key materials and intelligent equipment. As of today, it stands as the largest and most influential flagship event in the global battery sector.

Against the backdrop of accelerated upgrading of the lithium battery industry toward higher safety, higher precision as well as green and low-carbon development, dust control during production has become a core link to guarantee product quality, strengthen safety defense lines and realize eco-friendly manufacturing.

As a key component of the cleanliness system for lithium battery production, dust removal filter elements stand out in the Smart Manufacturing & Green Production exhibition area at this fair. Boasting outstanding strengths including high-precision filtration, anti-static and explosion-proof performance, as well as excellent corrosion resistance and durability, our filter elements have attracted widespread attention from the industry.

During the production of lithium battery cathode and anode materials such as lithium iron phosphate, lithium cobalt oxide and graphite, a large volume of ultra-fine combustible and explosive dust is generated in multiple working procedures, including material mixing, grinding, sieving, coating and calendaring. Most of these dust particles measure less than 10μm. If not properly treated, the dust will not only pollute the production environment and trigger quality issues such as cell short circuits and capacity degradation, but also lead to fire and explosion risks caused by static friction. Additionally, it will result in raw material waste and equipment abrasion, which hinder efficient production.

The lithium battery industry sets extremely stringent standards for dust removal filter elements. They are required to deliver high-precision filtration at 0.3μm grade with a filtration efficiency of no less than 99.9% to intercept ultra-fine dust. Superior anti-static performance is also essential to dissipate static electricity in a timely manner and eliminate potential fire and explosion hazards. Adopting zinc-free and copper-free materials prevents metal ion contamination on electrode sheets. Moreover, the products are tailored for high-dust and high-humidity working conditions, featuring corrosion resistance, durability and easy dust cleaning to ensure long-term stable operation.

Field Application Cases Put Product Performance to the Test

Thanks to reliable product performance, our series of lithium-battery dedicated dust removal filter elements have been widely deployed on the production lines of leading domestic lithium battery and material enterprises. They have delivered remarkable results under diverse working conditions, and have become key reference cases for numerous purchasers at this exhibition.

1. Large-scale Lithium Iron Phosphate Production Line

A leading domestic new energy material enterprise boasts an annual output of over 100,000 tons of lithium iron phosphate. Its grinding and granulation workshops feature high dust concentration, ultra-fine powder particles, and combustible & explosive dust.

After large-scale installation of our anti-static dust removal filter elements, the workshop dust emission concentration has steadily met relevant standards. The static dissipation performance fully complies with explosion-proof regulations. The service cycle of filter elements has been extended by 40%, greatly cutting annual filter replacement costs. Meanwhile, the problem of raw material loss caused by drifting ultra-fine powder has been thoroughly resolved.

2. Power Battery Cell Production Workshop

A well-known power battery manufacturer in South China faces frequent generation of fine copper & aluminum dust and electrode powder during electrode calendaring and slitting processes. Such metallic impurities tend to lower the cell yield rate.

Equipped with our zinc & copper free dedicated dust removal filter elements on site, the system effectively intercepts micron-sized metal dust and electrode powder. The workshop cleanliness is maintained at a stable standard level, leading to a notable drop in cell defect rate. Overall product consistency and safety performance have also been comprehensively improved.

3. Anode Graphite Processing Project for Energy Storage Batteries

Graphite powder is lightweight and highly adhesive, which easily causes clogging and difficult dust cleaning for conventional filter elements.

Tailored for such working conditions, our PTFE membrane dust removal filter elements feature excellent hydrophobic and anti-stick properties to ensure thorough pulse jet cleaning. Even under long-term high-dust operating environments, the filters maintain stable air flow rate, reducing equipment downtime and maintenance frequency. They are fully applicable to the full-process dust removal for graphite crushing and sieving.

Empowering Smart Green Manufacturing to Drive High-quality Industrial Development

At CIBF 2026, our lithium-battery dedicated dust removal filter elements stand out with core strengths of safety, high efficiency, high precision and long service life. Well integrated with intelligent manufacturing equipment and clean production solutions for lithium batteries, they serve as a key supporting product for the green, intelligent and high-quality development of the lithium battery industry.

From cathode and anode material production, cell manufacturing to dust recovery and environmentally compliant emission, dust removal filter elements run through the entire dust control workflow across the lithium battery industrial chain. They not only safeguard production safety and product quality, but also enable raw material recovery, energy consumption reduction and full compliance with environmental regulations. This perfectly echoes the exhibition theme of Empower Green Development, Shape the Future.

Against the backdrop of booming global new energy industry, the lithium battery sector will keep raising requirements for clean production, safety and environmental protection. Going forward, Longchen will continue to focus on R&D and product performance optimization. We will launch more customized filtration solutions for new energy sectors including lithium batteries and energy storage. Working hand in hand with upstream and downstream partners in the industrial chain, we will accelerate the transformation of China’s lithium battery industry from scale expansion to value upgrading, and contribute to the green, low-carbon and high-quality development of the global new energy industry.
