[0002] Currently, large-capacity batteries (also known as battery modules or battery packs) are often created by connecting multiple single cells in parallel or series. Compared to small-capacity batteries, large-capacity batteries typically require a larger volume and weight to accommodate more electrode materials and electrolytes. This limits their application in portable devices, especially in applications with strict size and weight requirements. Furthermore, large-capacity batteries require more sophisticated charge and discharge management during use to avoid damage to battery performance caused by overcharging and over-discharging, and they also present safety issues.
