Battery Separator Tensile and Puncture Testing Machine

Product Overview

This battery separator tensile and puncture testing machine is an advanced mechanical testing system engineered specifically to characterize the physical and structural properties of thin-film membranes and battery separators. By combining computer-controlled closed-loop actuation, precision motor transmission, and high-sensitivity load cell sensing, this equipment delivers rigorous evaluations of tensile strength, puncture resistance, elongation, and yield behavior across ultra-thin materials.

Designed for lithium-ion battery research facilities, quality assurance laboratories, and advanced polymer film production lines, the system provides critical mechanical benchmarking data. It empowers material scientists and manufacturing engineers to accurately evaluate puncture resistance against electrode burrs or dendrite formation, ensuring separators prevent internal short circuits and maintain structural integrity during cell assembly and cycling.

Built with heavy-duty structural rigidity and low-noise mechanical components, this testing instrument ensures consistent, repeatable performance across thousands of continuous test cycles. The integrated control software provides real-time tracking of force, displacement, deformation, and test speed, giving testing teams complete confidence in meeting strict industrial testing standards.

Key Features

• High-Precision Multi-Mode Actuation: The precision electric motor transmission delivers stable, smooth crosshead motion from 1 mm/min to 500 mm/min, ensuring strict compliance with dynamic tensile and low-velocity puncture testing protocols.
• High-Sensitivity Load Cell Sensing: Integrated sensor architecture provides a 200 N force capacity with a high resolution of 0.01% F.S. and a measurement accuracy of ±1%, enabling micro-force resolution on ultra-thin polymer films.
• Extended 800 mm Testing Stroke: The vertical crosshead clearance accommodates high-elongation polymeric separators, elastomeric substrates, and composite membranes without stroke limitation constraints.
• Accurate Deformation & Displacement Tracking: Features 0.01 mm displacement resolution and ±1% deformation accuracy over a wide 2% to 100% range for exact strain, yield, and elongation-at-break determinations.
• Dual Mechanical Testing Capability: Seamlessly switches between high-precision tensile grips and standardized puncture probe fixtures to evaluate tensile yield, ultimate tensile strength, puncture load, and puncture energy in a single platform.
• Computer-Integrated Software Control: Dedicated acquisition software allows multi-parameter control of force, displacement, deformation rate, and velocity with automated stress-strain curve generation, statistical logging, and automated reporting.
• Robust Structural Rigidity: Engineered with an anti-deflection single-column load frame that eliminates system compliance errors during delicate puncture and tensile cycles.
• Comprehensive Safety Architecture: Incorporates electronic upper and lower crosshead travel limiters, real-time load overload protection, and emergency stop features to safeguard operators and delicate sensor components.
