Lithium-ion batteries are crucial for a wide range of applications, including powering portable electronics, electrifying transportation, and decarbonizing the electricity grid. 1, 2, 3 In many instances, however, lithium-ion batteries only spend a small portion of their lifetime in operation, with the majority of their life spent under no applied load. 4 For example, electric …
Battery degradation poses significant challenges for energy storage systems, impacting their overall efficiency and performance. Over time, the gradual loss of capacity in batteries reduces the system’s ability to store and deliver the expected amount of energy.
The charge/discharge rate was found to have the most significant influence on these parameters, particularly the charging rate. These insights contribute to a better understanding of the risks associated with low-temperature aging and can aid in the prevention or mitigation of safety incidents.
As batteries degrade, their capacity to store and deliver energy diminishes, resulting in reduced overall energy storage capabilities. This degradation translates into shorter operational lifespans for energy storage systems, requiring more frequent replacements or refurbishments, which escalates operational costs.
Battery degradation also impacts on the overall efficiency of EVs. Table 3 presents a summary of the performance parameters of different types of lithium-ion battery. Darma et al. claimed that battery degradation decreases the travel range of EVs which leads to a decrease in the overall efficiency of EVs .
Several factors contribute to battery degradation. One primary cause is cycling, where the repeated charging and discharging of a battery causes chemical and physical changes within the battery cells. This leads to the gradual breakdown of electrode materials, diminishing the ability of the battery to hold a charge.
The rate of degradation increases with the charging/discharging rate, showing a linear growth relationship. Aging caused by high-rate charging/discharging leads to worsened safety features, especially at elevated temperatures. The severity of degradation further intensifies with higher rates of charging/discharging. 2.
