Battery manufacturing involves the production of batteries, which are devices that store electrical energy for use in various applications, from smartphones to electric vehicles. The process typically includes assembling components like electrodes, separators, and electrolytes, which are essential for the battery's function. The manufacturing process can vary depending on the type of battery, such as lithium-ion or lead-acid batteries. Quality control is crucial to ensure safety and efficiency, as batteries must meet specific standards to perform reliably in their intended applications.
