Lithium-ion batteries are a type of secondary battery designed for repeated charging and discharging cycles. They generate electrical energy through the movement of lithium ions between the cathode and anode. These batteries are widely integrated into electronic devices such as smartphones and laptops, and as a power source for electric vehicles. Despite their extensive adoption, the technology continues to evolve in fierce development competition worldwide, with ongoing efforts focused on improving energy efficiency, extending lifespan, and enhancing overall performance.<\/p>\n\n\n\n

If the cathode and anode of a lithium-ion battery come into direct contact, a short circuit can occur. Burrs or sagging on the processed surface may penetrate the separator and touch the opposite electrode. Therefore, strict quality control during electrode processing is essential.<\/p>\n\n\n\n

In this test, we used a specimen with a total thickness of 100\u202f\u03bcm, consisting of a 15\u202f\u03bcm aluminum substrate and the layer of active materials coated on one side, and conducted a punching test using our precision punching tool with a clearance of 2\u202f\u03bcm.<\/p>\n<\/div>\n<\/div>\n\n\n
