The attenuation of battery power performance results from capacity decay and impedance growth . ... ... In the battery community, empirical models are mainly used to predict the aging of the cell.
Consequently, ion transport through CEI, and within the cathode is largely slowed down, contributing an important part of capacity degradation. Moreover, the dissolve of transition metal, and change of crystal structure of cathode further trigger the capacity loss of batteries at low temperature.
However, faced with diverse scenarios and harsh working conditions (e.g., low temperature), the successful operation of batteries suffers great challenges. At low temperature, the increased viscosity of electrolyte leads to the poor wetting of batteries and sluggish transportation of Li-ion (Li +) in bulk electrolyte.
The aging mode of the battery is quantified by the capacity ratio of electrodes and the SOC bias of the positive electrode. To better understand the variation of internal parameters with battery aging, the simplified electrochemical model is used to identify the parameters in Ref. [ 24 ].
The design and development of the electrolyte can reduce the freezing point of the solvent, improve the ionic conductivity, and then, increase the capacity of the battery at low temperatures, which result in a considerable improvement in the discharge capacity of the LIBs at low temperatures [14, 16].
In the beginning, the loss of delithiated material in the negative electrode only has a weak effect on the battery capacity, because the negative electrode has excessive active substances, and the OCV curve of the negative electrode remains unchanged at the low SOC stage.

Attenuation causes slower signal rise times, rounding the front edge of the signal and increasing the likelihood of data errors (Figure 2). Dealing with attenuation-related distortion can be more challenging than dealing with the attenuation itself. Figure 2: In addition to reducing signal strength, attenuation is a source of signal distortion.
