Therefore the leakage current of the Lithium coin battery should be acquired in μA level to precisely estimate the state of charge (SOC) of the battery for utmost using harvested energy in indoor applications. The leakage current of a battery can be measured by the battery test equipment.
The leakage current of a battery can be measured by the battery test equipment. However, existing battery simulators are not accurate for small capacity Lithium coin batteries (such as 10 μA measurement accuracy in the dynamic model battery simulator of Keithley 2281S).
Hence, with the increase of applied voltage, leakage current increases accordingly. As seen from Fig. 4, at the final phase of the constant-voltage charging stage for the 1st cycle, the leakage current is 1.92, 0.70, 0.35, and 0.31 mA at the applied voltage of 4.1, 4.0, 3.9 and 3.8 V, respectively.

The leakage current at the applied voltage of 4.1 V is 2.7 and 6.2 times higher than that at 4.0 V and 3.8 V, respectively.
The leakage currents are the residual current when LIC cell was potentiostatically charged for 1 h at the voltage of 3.4–4.2 V. The leakage current of EDLC was measured at the constant voltage of 2.0–2.5 V. 3. Results and discussion Fig. 2 shows the cell voltage and electrode potential versus time during charging and discharging processes.
The leakage current at the applied voltage of 4.1 V is 2.7 and 6.2 times higher than that at 4.0 V and 3.8 V, respectively. Furthermore, we repeated this procedure for 3 additional times, and noticed that the leakage current decreased remarkably.
