Cycling degradation in lithium-ion batteries refers to the progressive deterioration in performance that occurs as the battery undergoes repeated charge and discharge cycles during its operational life . With each cycle, various physical and chemical processes contribute to the gradual degradation of the battery components .
Battery degradation can be described using three tiers of detail. Degradation mechanisms describe the physical and chemical changes that have occurred within the cell. Mechanisms are the most detailed viewpoint of degradation but are also typically the most difficult to observe during battery operation.
Mitigating battery degradation is critical for extending the lifespan of lithium-ion batteries, particularly in EVs and ESS. Here are several strategies to minimize degradation: Maintaining the battery charge between 20% and 80% is one of the most effective ways to prevent overcharging and deep discharging, which accelerate degradation.
Typically, a 1–3% annual degradation rate assumes one full cycle per day at moderate temperatures. More frequent cycling or operation in extreme temperatures can accelerate this degradation further. These degrade faster than lithium-ion batteries, with rates ranging from 4–6% annually.
However, this degradation rate can vary depending on several factors such as DoD, temperature and charging habits. For example, batteries cycled near 100% DoD degrade much faster than those cycled at 10% DoD. Typically, a 1–3% annual degradation rate assumes one full cycle per day at moderate temperatures.
Authors have claimed that the degradation mechanism of lithium-ion batteries affected anode, cathode and other battery structures, which are influenced by some external factors such as temperature. However, the effect of battery degradation on EV and energy storage system has not been taken into consideration.
