The voltage of the lithium ion battery drops gradually as it discharges, with a steep drop in voltage only towards the end. This rapid drop in voltage towards the end of the discharge cycle is the reason why Li-ion batteries need to be managed carefully to avoid deep discharges that can reduce their cycle life.
The most important key parameter you should know in lithium-ion batteries is the nominal voltage. The standard operating voltage of the lithium-ion battery system is called the nominal voltage. For lithium-ion batteries, the nominal voltage is approximately 3.7-volt per cell which is the average voltage during the discharge cycle.
This study investigates long-term capacity degradation of lithium-ion batteries after low temperature exposure subjected to various C-rate cycles. Findings reveal that low temperature exposure accelerates capacity degradation, especially with increased C-rates or longer exposure durations.
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 .
Degradation mechanism of lithium-ion battery . Battery degradation significantly impacts energy storage systems, compromising their efficiency and reliability over time . As batteries degrade, their capacity to store and deliver energy diminishes, resulting in reduced overall energy storage capabilities.
Xiong et al. presented a review about the aging mechanism of lithium-ion batteries . 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.
