With ultrasonication, the batteries are fully discharged in less than 2 hours, which is equivalent to a reduction of more than 90% in the required duration. As stated, the main reason for the time-consuming discharge of the LIBs was the deposition and corrosion caused by the reactions between the salt solution and the electrodes.
A typical discharge profile of the lithium–sulfur battery has two discharge plateaus at 2.3 and 2.1 V, which represent the conversions of S 8 to Li 2 S 4 and Li 2 S 4 to Li 2 S, respectively. In addition, at the end of discharge, Li 2 S is formed as the voltage drops.
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.
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.
External electrochemical discharge can be used to eliminate the effect of corrosion. Some measurement devices may involve in discharging the batteries during experiments. The demand for Lithium-ion batteries (LIB) is expected to increase exponentially due to the electrification of society.
