There are many reasons for the inconsistencies of lithium-ion batteries, which are mainly produced during the manufacturing process and the use process. Every step of the manufacturing process, such as the uniformity of the slurry during batching, the control of the areal density and surface tension during coating, will cause differences in the performance of the single cell.
CMXbattery engineer Studied the impact of lithium-ion battery manufacturing process on battery consistency, and focused on the impact of lithium-ion battery production and manufacturing processes on water-based binder system on battery consistency. During the use of the battery, Xie Jiao engineer al. Believed that the connection method and structural components / devices, the operating conditions and the environment will affect the consistency of the battery pack. Because the energy consumed by each connection point is inconsistent, the performance and aging rate of each component or structure are also inconsistent, so the impact on the battery is also inconsistent. In addition, because each cell in the battery is located differently, the temperature is different, and the performance degradation is also different, these will amplify the inconsistencies of the cell.
