Performance Evolution and Reliability Assessment of Energy Storage Systems under Challenging Operating Conditions

The rapid development of renewable energy integration, electrified transportation, smart grids, and flexible energy infrastructures has significantly increased the demand for advanced energy storage systems. Energy storage technologies, including batteries, supercapacitors, hydrogen-based storage, and hybrid energy storage systems, play critical roles in renewable energy utilization, power system flexibility, load balancing, and energy management. With the increasing deployment of energy storage systems in diverse applications, including electric vehicles, energy storage stations, microgrids, and renewable energy systems, their operating environments are becoming increasingly complex. Variations in temperature, charging and discharging conditions, cycling profiles, load fluctuations, and long-term operation can significantly influence the performance evolution, degradation behavior, and reliability of energy storage systems. Understanding the mechanisms behind performance changes and reliability degradation under challenging operating conditions is therefore essential for improving the long-term utilization and sustainable deployment of advanced energy storage technologies.This Research Topic aims to present recent advances in the performance evolution and reliability assessment of advanced energy storage systems under challenging operating conditions. While significant progress has been achieved in energy storage materials, device design, thermal management, battery management systems, and safety control technologies, several challenges remain in understanding degradation mechanisms, predicting system lifetime, identifying failure evolution pathways, and ensuring reliable operation throughout the service period. Emerging approaches, including multi-physics modeling, advanced characterization, intelligent monitoring, state estimation, and data-driven methods, provide new opportunities to analyze energy storage behavior, evaluate reliability, and develop effective strategies for lifetime improvement and safety enhancement. This Research Topic seeks to promote interdisciplinary research that bridges fundamental mechanisms and practical applications for more reliable and durable energy storage systems.This Research Topic welcomes Original Research Articles, Review Articles, Mini Reviews, Perspectives, Methods, and Case Studies addressing the performance evolution, reliability assessment, and safety challenges of advanced energy storage systems.
