Voltage rebound refers to a process where the battery voltage increases toward its steady-state value when there is no current pulse . 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.
Furthermore, a phenomenon called “voltage rebound” or “voltage relaxation” could impact the safety of the battery recycling process. Voltage rebound refers to a process where the battery voltage increases toward its steady-state value when there is no current pulse .
The underlining phenom-ena behind the rebound effect are not fully understood, but previous studies reported factors like temperature, state-of-charge (SOC), discharge speed, and battery age [22–24]. The voltage rebound phe-nomenon has been reported to last up to 24 h .
In the 5 wt% solutions, the voltage of the battery rose around 0.45 V, reaching 1.88 V. In contrast, in the 20 wt% NaCl electrolytes, the rebound voltage increased by >0.65 V. However, the final voltage is only 1.63 V. Thus, the experiments prove the hy-pothesis that faster discharge leads to a higher rebound voltage.
Among the discharge phenomena so far overlooked is the voltage recovery effect of batteries (a.k.a. voltage rebound/relaxation), where battery power appears to spontaneously surge, even after readings of full discharge in a circuit.
The current of the battery is i (t), which is positive on discharge and is negative on charge. The open-circuit voltage is higher than the terminal's voltage (v (t)) on discharge and lower than the terminal's voltage when the cell is being recharged.
