Special Issue Information

Dear Colleagues,

Lithium-ion batteries are the enabling technology for electric mobility, stationary storage and portable electronics. However, performance degradation over time remains a critical challenge, directly affecting reliability, safety and economic viability. Understanding aging mechanisms and developing accurate diagnostic and lifetime assessment methodologies are, therefore, essential to accelerate technological innovation and support large-scale deployment.

This Special Issue aims to gather cutting-edge research addressing the fundamental and applied aspects of lithium-ion battery aging. Contributions are welcome on physicochemical degradation mechanisms at material, cell and system levels, as well as on advanced characterization techniques, data-driven diagnostics and predictive modeling approaches. Emphasis is placed on linking degradation phenomena to measurable indicators and operational stress factors, including temperature, cycling conditions, fast charging and high-energy-density designs.

The Special Issue also encourages studies that bridge experimental investigation with modeling, artificial intelligence and digital twin approaches for state-of-health estimation and remaining useful life prediction. By integrating multi-scale understanding with advanced diagnostic tools, this collection seeks to support more reliable lifetime assessment frameworks and contribute to safer, longer-lasting and more sustainable lithium-ion battery technologies.

Potential topics include, but are not limited to:

  • Advanced characterization techniques for battery
  • Degradation study
  • State of health estimation
  • Impact of operating conditions on battery degradation
  • Lifetime prediction models and remaining useful life assessment
  • Analysis of lithium-ion batteries' aging mechanisms
  • Use of AI techniques for state-of-health estimation and lifetime prediction

Accurate battery state-of-charge (SOC) estimation is a core function of battery management systems (BMSs) for electric vehicles (EVs), as it directly affects energy management, safety, and reliability. However, battery aging significantly degrades the accuracy of conventional SOC estimation methods by causing capacity loss, increased internal resistance, and changes in voltage response characteristics. To address these issues, this study proposes an aging-aware SOC estimation method that combines an equivalent-circuit model (ECM) with an extended Kalman filter (EKF). In the proposed framework, aging effects are explicitly incorporated by using offline-identified SOH-dependent model parameters, including effective capacity, RC parameters, and SOC–OCV characteristics, and scheduling these parameters within the EKF prediction and correction process according to the available SOH information. Furthermore, the performance of the proposed method is experimentally validated under an Urban Dynamometer Driving Schedule (UDDS) using cylindrical lithium-ion cells with large current fluctuations. The experimental results demonstrate that the proposed aging-aware EKF maintains stable SOC estimation performance not only in the initial battery state but also throughout the gradual aging process and up to the end of battery life. These results demonstrate the potential of SOH-scheduled, aging-aware EKF-based SOC estimation to improve SOC accuracy in aged batteries under the investigated laboratory and dynamic load conditions.
