Learn MoreWhen the lithium-ion battery discharges, its working voltage always changes constantly with the continuation of time. The working voltage of the battery is used as the ordinate, discharge time, or capacity, or state of charge (SOC), or discharge depth (DOD) as the abscissa, and the curve drawn is called the discharge curve.
The discharge current is the amount of current drawn from the battery during use, measured in amperes (A). Li-ion cells can handle different discharge rates, but drawing a high current for extended periods can generate heat and reduce the battery's lifespan.
During discharge, lithium ions move from the anode back to the cathode. This movement generates an electric current, which powers your device. Proper discharge management is essential to avoid over-discharging, which can permanently harm the cell and diminish its capacity. 2. Li-Ion Cell Discharge Current
The discharge curve basically reflects the state of the electrode, which is the superposition of the state changes of the positive and negative electrodes. The voltage curve of lithium-ion batteries throughout the discharge process can be divided into three stages
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.
During the discharge of a LIB, the internal state of the battery is non-linear with heterogeneities in the concentration of the Li-ions in both electrodes and the electrolyte. When battery discharge is terminated, the current in the circuit is switched off, and the Li-ions move from an area of higher concentration to a lower concentration area.
