Differential Expansion and Voltage Model for Li-ion Batteries at ...
Differential voltage analysis (DVA) is a conventional approach for estimating capacity degradation in batteries. During charging, a graphite electrode goes through several phase transitions observed as plateaus in the voltage response. The transitions between these plateaus emerge as observable peaks in the differential voltage.
Lithium-ion battery lifetime extension: A review of derating …
As the derating factor changes with battery aging, the maximum and minimum values and the median/mean value of derating factors are presented to show the decreasing current/voltage. When the derating factor is less than one, the derating methods extend battery lifetime by a maximum of 290.7% and a minimum of 45.4%.
