This technology provides a cell structure for measuring battery samples in a sealed environment. It features a tightly coupled upper and lower cell structure, a sealant to prevent electrolyte leakage, a spring and moving screw for pressure control, and temperature and pressure sensors to precisely evaluate sample characteristics.
Conventional measurement devices have open cells, making it difficult to use volatile electrolytes. Furthermore, when measuring at the particle level, limitations such as poor contact between the sample and current collector, instability due to vibration, and external environmental interference have historically reduced measurement accuracy.
This technology forms protrusions and depressions where the upper and lower cells meet and applies a sealant to completely seal the sample. It is configured to finely adjust the contact pressure between the current collector and the sample using fixing screws, moving screws, and springs. Temperature and pressure sensors collect real-time data to enhance the accuracy of electrochemical evaluations. It can be applied to the analysis of pressure-dependent characteristics of single active material particles, the evaluation of volatile organic electrolyte cell behavior by temperature, and quality verification equipment for material companies, enabling the acquisition of highly reproducible electrochemical data under controlled mechanical and thermal conditions.
