Lithium Battery

Dust Collection in Battery Manufacturing

The battery production process, particularly in the electrode preparation workshop (feeding, slurry mixing, coating, rolling, and slitting), generates large amounts of combustible conductive dust containing materials such as cobalt, manganese, nickel, and graphite.

This dust not only poses a serious health hazard to employees but also poses a high risk of dust explosions. Furthermore, conductive dust can easily cause equipment short circuits, making it a key safety hazard in lithium battery factories.

Positive & Negative Electrode Batching / Mixing / Sieving Process

Application Scenarios: Full‑process for lithium‑ion material feeding, mixing, sieving and packaging.

Dust‑generating Characteristics: Continuous ultra‑fine‑powder dust emission throughout the process with high dust concentration. The dust is highly reactive and prone to static‑electricity‑triggered explosion. High powder‑purity requirement to avoid impurity contamination.
Electrode Coating / Calendering / Slitting / Die‑cutting Process

Application Scenarios: Electrode processing production lines for power batteries and energy‑storage batteries.

Dust‑generating Characteristics: Coating powder shedding, micro‑chips of copper & aluminum foils. Fine dust with strong adhesion may cause electrode defects and cell short‑circuits. Extremely high dust‑removal precision is required without damaging electrode substrates.
Cell Winding / Welding / Sealing Process

Application Scenarios: Cell assembly, tab welding, battery sealing and electrolyte injection processes.

Dust‑generating Characteristics: Low‑concentration floating dust, metallic welding fumes and aluminum‑plastic‑film micro‑dust. Strict cleanliness requirements for workshops. Excessive dust will directly reduce battery yield.
