Products Description
XW-LL-1D Tensile Testing Machines are widely used in battery manufacturing to verify the mechanical performance of materials and components, enhance battery reliability and safety, and support applications in material testing, process control, quality inspection, and more.
1. Material testing
Electrode materials: Evaluate the tensile strength of electrode materials (e.g., copper foil, aluminum foil) to ensure they resist breakage during production and use.
Battery separators: Test the tensile strength of separators to avoid internal damage within the battery.
2. Component testing
Battery tabs: Measure the welding strength between tabs and electrode sheets to confirm a secure connection.
Packaging materials: Assess the strength of battery casing and sealing materials to prevent leakage or deformation.
3. Process control
Welding quality: Examine the strength at weld joints to verify welding process stability.
Assembly force: Measure the applied force during component assembly to prevent over- or under-tightening.
4. Quality control
Peel test: Check coating or adhesive adhesion to ensure it does not easily detach.
Cycling test: Simulate mechanical stress during charge-discharge cycles to assess material durability.
5. R&D support
New material evaluation: Test the mechanical properties of new materials to optimize battery design.
Failure analysis: Analyze breakage or delamination points to improve material selection and manufacturing processes.
