In-Depth Analysis of Internal Cell Structural Characteristics, Operation Mechanism and Performance Optimization of Lithium Ion Batteries As the smallest core unit of energy storage and power battery systems, the cell fundamentally determines the battery’s capacity ceiling, cycle life, safety performance, discharge stability and weather resistance through its microscopic structure, material ratio and packaging technology. Compared with the external protection circuit, shell structure and management system, the internal cell architecture is the underlying carrier of core battery performance and the main source of performance attenuation and hidden faults during long-term operation. Many terminal battery problems such as bulging, sudden capacity drop, soaring internal resistance, poor low-temperature performance and insufficient thermal stability are not caused by improper later use, but by internal structural defects, unbalanced component matching and insufficient micro-process precis
