Characteristics and Behavior of Cycled Aged Lithium Ion Cells
Abstract
Data collected on "standard" Li-ion cells confirms a change in kinetic behavior as Li-ion cells cycle. The data shows distinct regions through out the cycle life of the cell. The data suggests that the net coulombic output as well as the relative state-of-charge maintained throughout the cells use is as important as total cycles and calendar time when considering cell aging. The data provides a valuable base for both improved charge routines and safety analysis.
