Accelerated aging at high temperatures may cause massive heat accumulation inside the battery, resulting in the thermal runaway of the battery, which is why the temperature rarely exceeds 60 °C in actual accelerated aging research. High-temperature cycling also affects the degradation of battery active materials.
These aging phenomena will result in increased battery resistance, battery short circuit, and other consequences . Separator aging is generally not considered in accelerated aging studies. This is because it has little impact on battery capacity in the early stage of battery lifetime.
For example, in order to store more energy, most LIBs used in ESSs are designed to be energy dense with poor rate performance. Consequently, they are not suitable for high current rate acceleration but rather more appropriate for SOC and DOD acceleration. For temperature, it is suitable for the accelerated aging of most types of batteries.
The main aging mechanisms of fast charging batteries are lithium plating and loss of active materials. Of course, accelerated aging would be pointless if the battery suffers significant lithium plating and active materials loss .
Accelerated aging methods are designed to accelerate the degradation of a product by subjecting it to harsher working conditions than normal use. For LIBs, it can be used to investigate the aging mechanisms and rapidly evaluate battery lifetime under various stress conditions.
Assuming that the increased SOC or DOD of the battery only accelerates the interfacial side reactions, causing a small amount of active lithium loss, then accelerated lifetime prediction becomes feasible . SOC accelerated aging is also the most commonly used method in battery calendar life research.
Externally, battery aging is noticeable as a measurable loss of capacity and increase in internal resistance. Behind this are a variety of chemical reactions and physical phenomena that influence the available amount of …

Accelerated aging, as an efficient and economical method, can output sufficient cycling information in short time, which enables a rapid prediction of the lifetime of LIBs under various working stresses. Nevertheless, the prerequisite for accelerated aging-based battery lifetime prediction is the consistency of aging mechanisms.
Battery form factors include cylindrical, pouch, and prismatic, and the chemistries include LCO, LFP, and NMC. The data from these tests can be used for battery state estimation, remaining useful life prediction, accelerated battery degradation modeling, and reliability analysis. A description of each battery and each test is presented below.
Extreme temperature, large charge-discharge rate, and high DOD are common accelerated aging factors in battery use. Besides, the cutoff voltage of charge and discharge …
