Metallic foreign matter removal: BYDRecent Research Landscape

Metallic foreign matter and residual dressing on pole pieces cause internal shorts and cell failure. These innovations utilize automated mechanical or sensing systems to eliminate surface debris and ensure electrochemical purity.

What technical problems is BYD addressing in Metallic foreign matter removal?

Internal metallic particulate contamination

(55)evidences

Residual metallic waste and particulate matter on battery electrodes cause internal short circuits and safety failures. Eliminating these contaminants prevents cell degradation and manufacturing defects.

Substrate surface particulate contamination

(35)evidences

Foreign matter on foil surfaces during high-tension coating and curing causes electrode defects. Eliminating these contaminants prevents short circuits and improves battery cell reliability.
