Lithium Battery Anode Die-Cutting Process Dust Control

Project Overview

This project addresses dust control for lithium battery anode die-cutting. A high-efficiency pulse cartridge dust collection system from Detai Technology captures and purifies anode active dust, copper foil debris, and conductive agent dust from die-cutting operations. It meets lithium battery workshop standards for high cleanliness, anti-static/explosion-proof performance, and continuous operation, delivering reliable dust control for electrode forming processes.

On-Site Pain Points

• High-speed stamping generates ultra-fine graphite dust and copper foil debris that adhere to electrodes, causing secondary contamination and reducing battery yield/safety.
• Anode graphite dust is flammable/explosive and prone to static buildup, creating major safety hazards.
• High-speed continuous production demands stable airflow, thorough cleaning, and low maintenance without disrupting production rhythm.

Application Results

• Workshop dust concentration falls significantly; electrode defect rates decline, and battery yield rises steadily.
• Dust-related wear on molds/guides is eliminated, reducing failures and extending maintenance intervals.
• Safe, stable operation passes lithium battery industry safety and environmental audits.
• Low noise and simple maintenance align with high-speed anode die-cutting production rhythms.
