Over the lifetime of a battery, a variety of aging mechanisms affect the performance of the system. Cyclic and calendar aging of the battery cells become noticeable as a loss of capacity and an increase in internal resistance.
In this work, the aging factors of lithium batteries are classified, and the influence of positive and negative aging of battery on lithium battery is analyzed. The aging mechanism of lithium battery is divided into the loss of active lithium ion (LLI), the loss of active material (LAM) and the increase of internal resistance.
However, the aging of batteries is not only the reduction of SOH, but also accompanied by the weakening of battery charging and discharging capacity and the deterioration of battery stability. The charging and discharging capacity of batteries with high aging degree will change significantly under extreme conditions [ 83, 84 ].
The research progress of scholars in various fields in battery aging mechanism is summarized. The modeling method of lithium battery aging and SOH prediction method are described. This work provides theoretical reference for extending the service life of power batteries and the design of battery management system. 2.
The external factors will eventually show up inside the battery. External factors are also important reasons for the intensification of internal aging. Internal aging of the battery eventually causes varying degrees of internal resistance increase, loss of active lithium ions and loss of active materials.
During battery operation, the electrodes and electrolyte undergo several degradation mechanisms. The aging modes which significantly affect the electrodes are Loss of Lithium Inventory (LLI), loss of active mass and corrosion of current collectors.
