Let’s delve into the nitty-gritty of this: Electrolyte Decomposition: The electrolyte, a key player in a battery, is prone to decomposition over time, which affects battery capacity. Solid Electrolyte Interface (SEI) Layer Formation: Lithium-ion batteries often form an SEI layer over time, which reduces ion movement and thus, battery capacity.

Lithium-ion batteries are widely used for energy storage in electric vehicles (EV), energy-storage stations, and other situations, owing to their high energy density and low cost [ 6, 7 ]. However, an unsuitable operating temperature and charging rate can have significant negative impacts on the service life of lithium-ion batteries [ 8, 9 ].
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.
In 2003 it was reported the typical range of capacity loss in lithium-ion batteries after 500 charging and discharging cycles varied from 12.4% to 24.1%, giving an average capacity loss per cycle range of 0.025–0.048% per cycle.
Therefore, even if lithium-ion battery has a high CE, it may not be energy efficient. Energy efficiency, on the other hand, directly evaluates the ratio between the energy used during charging and the energy released during discharging, and is affected by various factors.

Capacity fading in Li-ion batteries occurs by a multitude of stress factors, including ambient temperature, discharge C-rate, and state of charge (SOC). Capacity loss is strongly temperature-dependent, the aging rates increase with decreasing temperature below 25 °C, while above 25 °C aging is accelerated with increasing temperature. Capacity loss is C-rate sensitive and higher C-rates lead to a faster capacity loss on a per cycle. …
