The consequences of discharging with higher current are that you manage to get less energy than specified from the battery. The current peaks create voltage drops and at the moment when that voltage drop goes below your brown-out voltage - your circuit resets. Needless to say at that point there is still some energy left in the cell. To

6 FAQs about [Lithium battery withstand voltage leakage current]

What is the maximum leakage current of a lithium ion battery?

However, after high-acceleration impacts ranging from 15,527 to 42,608 g, the self-discharge leakage current of the battery markedly surged to 39.16, 96.31, 107.3, and 890 μA, respectively. The maximum leakage current is 146 times that before the impact, a loss too substantial to ignore.

What is the leakage current of a lithium coin battery?

When the rechargeable Lithium coin battery is employed as the storage component for indoor energy harvesting, the leakage current of the battery cannot be ignored, especially in ultra-low-power applications. The leakage current of the Lithium coin battery is commonly believed in the low μA range. However the exact value is unknown.

What happens if a lithium ion battery is damaged?

Damage to the cathode material leads to a slightly lower battery potential upon full recharge after impact and causes partial capacity loss of the lithium-ion battery. 3.3. Discussion on the redundancy design of a Li-ion battery under high-dynamic impacts

What happens if a lithium battery reaches 90 °C?

Once the temperature of LiBs surpasses 90 °C, the exothermic chemical reactions within the battery accelerate, initiating a positive feedback loop of increased heat generation. The escalating temperature can lead to thermal runaway, ultimately resulting in fires and explosions [2, 3].

Can battery leakage current be measured by a battery simulator?

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).

What happens if a charge current is larger than a leakage current?

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.
