Understanding the mechanisms of battery aging, diagnosing battery health accurately, and implementing effective health management strategies based on these diagnostics are recognized as crucial for extending battery life, enhancing performance, and ensuring safety [7].
Accurate predictions of the remaining battery lifetime at different operating conditions are essential for the battery management system to avoid potentially dangerous battery failures and guarantee reliable and efficient operation. The remaining battery lifetime information is also critical for battery second-life applications.
The aging effect in storage and in use will affect the cycle life of the battery. The negative electrode aging dominates the battery aging, and the side reaction plays a key role in the aging process. The interaction between the surface of negative electrode materials and electrolyte to form SEI has been widely studied and described. I.
Battery aging diagnosis and SOH prediction are to improve battery performance from the internal mechanism, so as to extend battery life and realize real-time monitoring of battery life. The tracking of aging characteristics of retired battery packs and the online evaluation system of SOH need to be improved.
However, the aging of batteries is not only the reduction of SOH, but also accompanied by the weakening of battery charging and discharging capacity and the deterioration of battery stability. The charging and discharging capacity of batteries with high aging degree will change significantly under extreme conditions [83, 84].
Lithium-ion batteries are widely used in energy-storage systems and electric vehicles and are quickly extending into various other fields. Aging and thermal safety present key challenges to the advancement of batteries. Aging degrades the electrochemical performance of the battery and modifies its thermal safety characteristics.
Therefore, researchers can not only predict the future performance of the battery (e.g., resistance increment, SEI formation, and change in the voltage curve) without time-consuming aging tests but also optimize battery design to improve expected performance metrics.
Common SOH prediction methods. Under unrelated conditions (offline), measuring the aging parameters (capacity, internal resistance, etc.) of lithium-ion batteries to obtain the characteristic parameter values of the battery at this time, and finally using the SOH definition to evaluate the current degree of battery attenuation.
