Purpose

During the charging and discharging process of lithium-ion batteries, the insertion and extraction of lithium ions in the positive and negative electrodes cause changes in the volume of the electrodes and the generation of gas, resulting in changes in the expansion force of the battery; The change in expansion force of lithium-ion batteries will have an adverse effect on their electrochemical performance, which may lead to a decrease in battery capacity and a shortened lifespan. Therefore, monitoring battery expansion during charging and discharging processes is necessary

The significance of the change in swelling force is obvious;

Monitoring the expansion and deformation changes of lithium-ion batteries provides accurate reference for compact design of battery modules and packs, and provides effective data support for energy density and safety considerations of battery packs;

characteristic

Pressure loading uses digital settings, eliminating the need for manual operation and external pressure regulating devices. It is easy to operate and has good repeatability; Servo control combined with high-precision pressure sensor closed-loop control, high pressure accuracy, fast loading and unloading response; Independent digital display and real-time collection and storage of testing pressure, timely cut-off of testing and saving of data in case of poor testing, dynamic display of testing process curve, more intuitive; Both test data and test waveforms can be stored on the computer's hard drive, which can be reopened for viewing, analysis, and comparison, facilitating data traceability;
