BATTERY AND TERMINAL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17788684 titled 'BATTERY AND TERMINAL DEVICE
Simplified Explanation
The abstract describes a battery with at least two ports that has a unique structure, including electrodes with protruding tabs and a non-edge area for tab placement. This design allows for stronger fast charging capability, improved heat dissipation, and even distribution of stress inside the battery. These features help alleviate interface deterioration, reduce the risk of shading and lithium plating, and enhance battery performance.

Original Abstract Submitted
The battery provided in this application and having at least two ports is obtained by winding a first electrode and a second electrode that have a novel structure (for example, a plurality of tabs separately protrude from a first long side and a second long side of an electrode, and the tabs are disposed on a non-edge area). In addition, in the terminal device including the battery, the battery and another charging/discharging component may form at least two charging/discharging links, so that the terminal device can have a stronger fast charging capability, and heat dissipation pressure of each charging/discharging link can be relieved. Moreover, stress inside the battery is evenly distributed, so that interface deterioration of the electrode that is caused by stress unevenness can be alleviated. This effectively reduces a risk of shading and lithium plating generated in a cathode charging/discharging cycle, and improves performance of the battery.
