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.
The main aging mechanisms of lithium-ion batteries include loss of positive active materials (LAMp), loss of negative active materials (LAMn), loss of lithium inventory (LLI), etc . Electrochemical side reactions are the main cause of battery aging. ... ... Similarly, the aging of the battery is evaluated by a capacity decay model .
In our previous work , we found that the attenuation of battery capacity will lead to the change of electrode OCV.
The indirect method is based on voltage, current, and temperature, combined with incremental capacity analysis (ICA), differential thermal voltammetry (DTV) and other means to evaluate cell aging. The cyclic aging behavior of lithium-ion batteries at room temperature is investigated by ICA and differential voltage analysis (DVA) in Ref. [ 9 ].
Given their high energy/power densities and long cycle time, lithium-ion batteries (LIBs) have become one type of the most practical power sources for electric/hybrid electric automobile, portable electronics, and power plants. However, the performance attenuation of LIBs has limited their applications in many energy-related systems.
