Abstract:

The significance of a reference electrode in elucidating internal physical and chemical processes in high-safety, high-performance lithium batteries cannot be overstated. Despite this importance, constructing and integrating a reliable reference electrode remains a challenge in academic research and product development. In this study, we explore the fundamental principles and characteristics of reference electrodes for lithium batteries. In addition, we outline key design parameters, including the selection of active materials, geometric dimensions, manufacturing processes, and detection setups. Furthermore, we present the application of a three-electrode system that integrates the reference electrode to analyze the working and failure mechanisms of lithium batteries. This approach enhances our understanding of the complex electrochemical processes within the battery system. In conclusion, we discuss the challenges associated with developing and deploying reference electrodes for lithium batteries, along with prospective directions for future research and implementation.
