Battery Separator Wetlaid Nonwoven Production
topic
Battery separator wetlaid nonwovens from glass microfibre, polyethylene, and composite fibre blends provide the porous ion-permeable separator in lead-acid batteries and some lithium-ion battery formats, with absorptive glass mat separators soaking and retaining electrolyte while maintaining electronic insulation between electrodes at precisely controlled basis weight, thickness, and porosity calibrated to battery electrochemistry requirements.
Role
Provides the critical functional component of absorbed glass mat lead-acid batteries used in automotive and UPS applications where the absorbent glass microfibre separator holds liquid electrolyte in contact with the electrode plates while preventing electrical short circuits, with separator wetlaid quality parameters including basis weight uniformity, thickness, and wettability being critical determinants of battery performance and service life.
