Hengyi HY-0580UKNN PE Lithium-Ion Battery Separator Tensile & Puncture Strength Tester

Overview

The Hengyi HY-0580UKNN PE Lithium-Ion Battery Separator Tensile & Puncture Strength Tester is a high-precision electromechanical universal testing system engineered for mechanical characterization of thin-film battery components—specifically polyethylene (PE) microporous separators used in lithium-ion cells. Operating on the principle of controlled uniaxial force application and displacement measurement, the instrument complies with standardized test methodologies defined in ISO 1798, ASTM D882 (tensile properties of thin plastic sheeting), ASTM D3763 (instrumented impact resistance), and ISO 8510-2 (puncture resistance of flexible barrier materials). Its dual-capability architecture enables simultaneous validation of critical mechanical integrity parameters—including tensile strength, elongation at break, puncture force, and modulus—under both static and dynamic loading profiles. Designed for R&D laboratories, QC departments, and battery material suppliers, the system supports traceable, repeatable evaluation of separator performance under simulated cell assembly and operational stress conditions.

Key Features

• Modular load cell configuration supporting 12 selectable capacities (1 N to 5000 N), enabling high-resolution measurement across ultra-thin films (e.g., 9–25 µm PE separators) and robust composite laminates.
• Constant-force, constant-strain, and constant-displacement control modes compliant with ISO 527-1 and ASTM E8/E8M for standardized mechanical property derivation.
• High-fidelity motion control with speed range from 0.001 to 500 mm/min and accuracy better than ±0.5% of setpoint—critical for low-speed creep or high-rate puncture simulation.
• Integrated electronic limit protection, real-time overload detection (>110% FS), and auto-diagnostic routines for drive electronics, load sensing, and position feedback subsystems.
• Adjustable crosshead travel (800 mm) and 120 mm effective test width accommodate standard separator strips (e.g., 15 × 100 mm per IEC 62660-1) as well as multi-layer laminates and coated foils.
• Bi-directional crosshead movement with fast/slow manual override and programmable return-to-start functionality for high-throughput batch testing.

Sample Compatibility & Compliance

The HY-0580UKNN accommodates a broad spectrum of thin-film and fibrous specimens relevant to electrochemical energy storage systems. Validated sample types include monolayer and trilayer PE/PP separators, ceramic-coated separators, PVDF-based microporous membranes, aluminum/copper current collector foils (6–20 µm), conductive adhesives, and tab weld joints. The system meets mechanical test requirements outlined in IEC 62660-1 (secondary lithium cells), UL 2580 (battery safety), and GB/T 36363–2018 (Chinese national standard for lithium-ion battery separators). All force, displacement, and strain data are acquired with metrological traceability to national standards; calibration certificates conform to ISO/IEC 17025 and support GLP/GMP audit readiness.

Software & Data Management

Equipped with Hengyi’s proprietary WinTest v4.2 software, the system provides real-time force-displacement curve acquisition, multi-channel synchronized data logging (up to 10 kHz sampling), and automated report generation per ASTM E1391 and ISO 14644-1 templates. Software features include customizable test protocols (predefined or user-defined), digital signature support for operator authentication, audit trail logging (per FDA 21 CFR Part 11 requirements), and export compatibility with CSV, PDF, and XML formats. Raw data files retain full metadata—including environmental timestamps, calibration IDs, operator credentials, and instrument firmware version—for regulatory documentation and inter-laboratory comparison.

Applications

• Quantification of tensile strength, yield point, and elongation at break for PE separators under dry and wet (electrolyte-soaked) conditions.
• Puncture resistance evaluation using hemispherical or flat-tipped probes per ISO 8510-2, simulating dendrite-induced mechanical failure.
• Peel strength measurement of separator–electrode laminates and thermal shutdown layer adhesion interfaces.
• Mechanical screening of novel separator coatings (e.g., Al₂O₃, SiO₂) for crack propagation resistance and delamination onset.
• Compression modulus analysis of stacked separator-electrode assemblies under stack pressure (0.1–5 MPa range).
• Validation of aging effects—thermal, oxidative, or electrolyte-induced—on mechanical degradation kinetics via time-dependent creep and stress-relaxation tests.

FAQ

What standards does the HY-0580UKNN comply with for battery separator testing?
It supports test execution per ISO 1798, ASTM D882, ASTM D3763, IEC 62660-1, and GB/T 36363–2018, with configurable test parameters aligned to each standard’s procedural requirements.
Can the system perform both tensile and puncture tests without hardware reconfiguration?
Yes—the modular fixture interface allows rapid tooling change between tensile grips, puncture probes, peel fixtures, and compression platens, all within <60 seconds and without recalibration.
Is the force measurement traceable to national metrology institutes?
All load cells are supplied with valid calibration certificates traceable to CNAS-accredited laboratories (equivalent to ILAC-MRA signatories), and optional UKAS/NIST-traceable recalibration services are available.
Does the software support 21 CFR Part 11 compliance for pharmaceutical or medical battery applications?
Yes—WinTest v4.2 includes role-based access control, electronic signatures, immutable audit trails, and data integrity safeguards required for regulated environments.
What is the minimum measurable force resolution for 10 N load cell configuration?
With ±500,000-count resolution and no internal range switching, the system achieves sub-mN resolution (≤0.02 mN) across the full 0–10 N span, essential for detecting early-stage micro-yield in ultra-thin separators.
