Introduction: The Hidden Weakness in High-Performance Batteries In the race for higher energy density, battery manufacturers—whether for Electric Vehicles (EVs) or advanced Solar PV cells—are pushing materials to their limits. We focus heavily on chemistry and capacity, but we often overlook a mechanical "silent killer": Adhesion Failure.
If an electrode coating peels off the current collector, or a busbar detaches from a solar cell, the product fails. For years, quality control labs relied on standard 180° peel tests. But in the real world, stress doesn't always happen in a straight line. To predict the true lifespan of next-generation energy products, you need to see the whole picture. This is where the TOPHUNG Multi-Angle Battery Stripping Tester is revolutionizing the R&D landscape.
Why "Standard" Peeling Tests Are No Longer Enough Traditionally, ASTM or ISO standards dictate a fixed angle (usually 90° or 180°) for peel testing. While effective for basic QC, these fixed angles miss critical data points:
Complex Geometries: In cylindrical or prismatic battery cells, electrode tabs withstand stress at varying angles during swelling and contraction.
Inconsistent Coatings: A coating might pass a 90° test but fail catastrophically at 45° or 135°, revealing micro-cracks that shorten battery cycle life.
Real-world Simulation: Flexible electronics and wearable batteries are constantly twisting. A static 90° test cannot simulate the dynamic forces these products endure.
The Solution: Tophung’s Variable Angle Precision The TOPHUNG Multi-Angle Battery Stripping Tester transforms how engineers analyze adhesion strength. Unlike rigid, single-function testers, this machine is designed for the versatility required by modern material science.
Key Features That Matter for 2026:
Adjustable Testing Angles: The core innovation allows operators to test peel strength at various angles (e.g., 45°, 90°, 135°, 180°). This helps plot a "failure curve," giving researchers a complete understanding of how the adhesive or coating behaves under different stress vectors.
High-Sensitivity Sensors: Battery electrode coatings (like Anode/Cathode materials on copper/aluminum foil) are delicate. Our high-precision load cells capture micro-fluctuations in force that heavy-duty industrial machines miss.
Specialized Fixtures: Whether you are testing the stripping strength of lithium battery electrodes or the adhesion of PV ribbons on solar cells, our specialized clamps ensure the sample is held securely without inducing secondary damage.
Application: Where is this Machine Essential? This equipment is not just for one industry. It is a critical asset for:
Lithium-Ion Battery R&D: optimizing the binder formulation to ensure active materials stay attached to the foil during thousands of charge cycles.
Solar Photovoltaic (PV) Manufacturing: Testing the peel strength of silver paste and busbars to prevent delamination in harsh outdoor environments.
Flexible Electronics: Ensuring that conductive layers do not peel off when the device is bent or folded.
Conclusion: Invest in Precision, Secure Your Reputation In the competitive energy market, a batch of batteries that fail prematurely due to delamination can destroy a brand's reputation. The difference between a "good" battery and a "great" one often lies in the mechanical integrity of its internal layers.
Don't guess how your materials will behave. Test every angle. Upgrade your lab with the TOPHUNG Multi-Angle Battery Stripping Tester and ensure your products are built to last.
