Possibility of using features to indicate battery aging patterns and cycle life
This pattern highlights that an important factor contributing to the degradation of battery capacity, from 10 % to 20 %, is the deterioration of the electrode’s material and the resulting loss of available Li-ions. In the microscopic morphology observations, no evidence of Li-plating was identified in any of the four test cases.
Capacity loss can be defined as an irreversible loss of the ability of the battery to store charge . A higher internal resistance reduces the efficiency of the cell, which leads to less usable energy being available and more heat being generated.
