HAIDA HDV-001 Membrane Mechanical Strength Tester for Battery Separators

Overview

The HAIDA HDV-001 Membrane Mechanical Strength Tester is a purpose-built mechanical testing system engineered for quantitative evaluation of critical mechanical integrity parameters in microporous polyolefin and ceramic-coated separator films used in lithium-ion and sodium-ion battery cells. It operates on standardized uniaxial tensile and quasi-static puncture principles compliant with ISO 1798, ASTM D882, ASTM D3763, and GB/T 2792–2014 methodologies. The instrument applies controlled force via servo-motor-driven crosshead displacement while synchronously measuring load (N) and displacement (mm) with high-resolution transducers and encoder feedback. Its design prioritizes repeatability under low-force regimes (0.1–500 N range typical), essential for characterizing thin (<30 µm), anisotropic, and moisture-sensitive separator substrates without edge slippage or premature yielding.

Key Features

• Modular dual-test configuration: integrated tensile module and puncture module—both independently calibrated and interchangeable without realignment
• High-precision load cell with ±0.5% full-scale accuracy and 0.01 N resolution, traceable to NIM (National Institute of Metrology, China)
• Adjustable grip geometry accommodating strip widths from 5 mm to 25 mm and film thicknesses from 8 µm to 50 µm
• Self-aligning puncture probe (diameter: 1.0 mm, hemispherical tip per ASTM D3763) with automatic zero-force compensation prior to contact
• Thermally stable aluminum frame with vibration-damping base, minimizing environmental interference during sub-1 N measurements
• Compliance with GLP documentation requirements: all test parameters—including preload, rate, hold time, and failure criteria—are programmable and digitally logged

Sample Compatibility & Compliance

The HDV-001 supports standard separator formats including dry-process PP/PE biaxially oriented films, wet-process PE monolayers, PVDF-coated ceramic composites, and nonwoven-glass hybrids. Sample clamping employs pneumatic or manual dual-grip systems with serrated jaws and adjustable pressure (0.1–0.8 MPa) to prevent slippage without inducing localized deformation. All test protocols align with international regulatory expectations for battery material qualification: data outputs satisfy audit requirements under IATF 16949, ISO 9001:2015, and support submissions to UL 1642, UN 38.3, and GB/T 31485–2015. Calibration certificates include uncertainty budgets per ISO/IEC 17025:2017.

Software & Data Management

HAIDA TestSuite v3.2 software provides full control, real-time visualization, and automated report generation in PDF and CSV formats. The interface supports multi-step test sequences (e.g., preconditioning at 23 °C/50% RH per ISO 291, followed by tensile ramp-to-failure at 50 mm/min). Audit trails record operator ID, timestamp, firmware version, calibration status, and raw sensor data—fully compliant with FDA 21 CFR Part 11 when deployed with optional electronic signature and role-based access controls. Raw force-displacement curves are exportable for third-party analysis (e.g., MATLAB, OriginPro) and include metadata tags for lot traceability (batch ID, sample ID, ambient conditions).

Applications

• Quantification of tensile strength (MPa) and elongation-at-break (%) for incoming separator qualification
• Evaluation of puncture resistance (N) to assess dendrite penetration resistance during cell cycling
• Comparative aging studies: mechanical degradation after thermal exposure (85 °C/90% RH, 24–168 h) or electrolyte immersion (LiPF₆ in EC/DMC)
• Process validation of coating uniformity and calendering effects on mechanical anisotropy
• Supporting DOE (Design of Experiments) for separator formulation optimization in R&D labs
• Generating data packages for OEM battery safety certification and tier-1 supplier audits

FAQ

Does the HDV-001 comply with ASTM D882 for thin plastic film testing?
Yes—the instrument implements the exact gauge length (50 mm), crosshead speed (50 mm/min), and specimen conditioning requirements specified in ASTM D882-22, with documented verification reports available upon request.
Can it test separators with ceramic coatings or surface treatments?
Yes—its low-noise load measurement architecture and adaptive grip pressure control prevent delamination artifacts during initial loading, enabling reliable characterization of coated and laminated architectures.
Is software validation documentation provided for regulated environments?
Yes—IQ/OQ protocols, URS mapping, and 21 CFR Part 11 compliance checklists are included in the Validation Support Package (optional add-on).
