The open-circuit voltage test cell is not a conventional single cell used for energy storage and discharge, but rather a standardized test cell specifically designed for accurate and repeatable open-circuit voltage measurements. Through a highly controlled chamber structure, carefully selected inert materials, and precise assembly processes, it provides researchers with an ideal testing environment that eliminates interference and focuses solely on the intrinsic characteristics of the electrolyte. It serves as a laboratory benchmark instrument for evaluating electrolyte SOC and diagnosing system imbalances.
