As the world transitions toward cleaner, more sustainable energy, the demand for lithium batteries has surged dramatically in recent years. Lithium batteries have become the preferred energy storage solution for a wide range of applications, including electric vehicles, consumer electronics, and renewable energy storage systems. Accordingly, the global lithium battery industry has been experiencing substantial growth, with reports indicating a projected compound annual growth rate of 15.8% from 2023 to 2030. With this growth comes the need for consistent and reliable quality control measures to ensure the safety and performance of these batteries. One such technology is the use of battery X-ray inspection for battery quality control. Battery X-ray inspection is a powerful tool that is highly effective throughout the entire battery manufacturing process and lifecycle management.
SEAMARK's battery X-ray inspection is based on the principle of X-ray transmission. An X-ray generator produces high-energy X-rays that penetrate the battery and encounter various substances of different densities within the battery, such as electrolytes, electrodes, and separators. Because different materials absorb X-rays to varying degrees, the rays exhibit different levels of attenuation after passing through. These attenuated rays are then received by an image intensifier, which processes them through a series of image treatments to finally produce an X-ray image. These images can clearly display the internal structure and components of the battery, providing crucial insights for quality control, fault analysis, and research and development improvements.
X-rays can detect hidden defects within materials, aiding in the inspection of various industries involved in the battery supply chain, including mining, raw material processing, film inspection, battery packs and modules, fault analysis, and battery recycling. Detecting defects in battery cells before they are assembled into modules can save resources and provide feedback for optimizing the manufacturing process.
SEAMARK's battery X-ray inspection technology is a non-destructive testing method that allows manufacturers to inspect the internal components of a battery without damaging it. By using battery X-ray inspection technology, any defects or anomalies in the internal structure of the battery that could compromise its safety or performance can be identified. This includes detecting voids, cracks, or foreign particles that might have been introduced during the manufacturing process. Given the complex internal structure of lithium batteries, X-ray imaging is particularly suitable for them. Lithium batteries consist of multiple layers, each serving a specific function, such as the anode, cathode, and electrolyte. X-ray imaging helps manufacturers ensure the uniformity and correct positioning of each layer, which is crucial for the overall performance and safety of the battery. Furthermore, X-ray imaging is a fast and efficient quality control method that can be easily integrated into the manufacturing process. It allows manufacturers to conduct real-time inspections of batteries, reducing the risk of overlooking defects and minimizing potential safety issues.
