This paper aims to analyze the aging mechanism of lithium-ion batteries in calendar aging test processes and propose a SOH estimation model which does not rely on the input of battery aging history. In the aging mechanism analysis, both time domain data and frequency data are analyzed to explore the internal behaviors of lithium-ion batteries.
In the aging mechanism analysis, both time domain data and frequency data are analyzed to explore the internal behaviors of lithium-ion batteries. DVA is mainly carried out in the time domain analysis.
The aforementioned reactions have different impacts on battery capacity loss in a specific aging process [72, 73], which can be used to diagnose the aging of batteries. At present, the diagnosis methods can be classified into three categories: disassembly-based post-mortem analysis, curve-based analysis, and model-based analysis.
It is necessary to study battery aging mechanisms for the establishment of a connection between the degradation of battery external characteristics (i.e. terminal voltage or discharging power) and internal side reactions, in order to provide reliable solutions to predict remaining useful life (RUL), estimate SOH and guarantees safe EV operations.
Ageing characterisation of lithium-ion batteries needs to be accelerated compared to real-world applications to obtain ageing patterns in a short period of time. In this review, we discuss characterisation of fast ageing without triggering unintended ageing mechanisms and the required test duration for reliable lifetime prediction.
Since the aging reactions include cathode degradation, anode degradation, and SEI formation , their respective contribution rates to battery aging can be calculated as the equivalent capacity loss which is considered as the amount of active lithium-ion loss.
