The discharge characteristics of lithium-ion batteries are influenced by multiple factors, including chemistry, temperature, discharge rate, and internal resistance. Monitoring these characteristics is vital for efficient battery management and maximizing lifespan.
Understanding the Discharge Curve The discharge curve of a lithium-ion battery is a critical tool for visualizing its performance over time. It can be divided into three distinct regions: In this phase, the voltage remains relatively stable, presenting a flat plateau as the battery discharges.
Specifically, the influence of the discharge rate on the deterioration of lithium metal electrodes remains poorly understood. In this study, pouch-type Li|NMC811 cells were fabricated employing a lean electrolyte, and a comprehensive exploration was conducted into the effects of the discharge rate on the battery performance.
Less lithium-ion battery charging and discharging are more beneficial to prolong the life of the lithium-ion battery. As shown in Figure 7, the SOC of HESS gradually increases at night, while during the day, it is slowly decreasing.
At the 150th charging cycle, the charging voltage plateau of the LIB increases overall, indicating that the polarization phenomenon in the aging battery is more obvious, and the batteries cycling under −10 and −20 °C can only be charged at a constant voltage.
The limitations of conventional energy storage systems have led to the requirement for advanced and efficient energy storage solutions, where lithium-ion batteries are considered a potential alternative, despite their own challenges .
