Customer ServiceTherefore 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).
When the applied charge current is larger than the leakage current, a positive sign (terminal voltage increase) can be observed. Otherwise a negative sign appears. By gradually changing the charge current using the successive approximation search algorithm, the leakage current will finally converge to the applied charge current.
There was an immediate voltage change when the high rate pulses were applied. The maximum current that could be applied to the cathodes, at the rated charging voltage limit for the cells, was around 10 C. For the anodes, the limit was 3–5 C, before the voltage went negative of the lithium metal counter electrode.
While lithium ion technology has matured, risk of failure, fire and even explosion while in use is an ongoing concern for battery makers. In order to decrease the risk of failure in the field – and these failures can be catastrophic - the root cause must be identified and any defective cells must be filtered out before they reach the end user.
The cell was charged and discharged with a current of ±40 mA between 2.75 V and 4.2 V. Voltage increases steadily while charging the battery. During this step, lithium ions are extracted from the cathode and intercalate into the anode’s graphite layers. The cell is potentiostatically held at 4.2 V after reaching the upper voltage limit.
