Lithium batteries leak only in certain situations. The main reasons for lithium battery leakage include poor manufacturing quality, improper use, overcharging, mixing of different models of batteries, etc. Lithium battery leakage may cause the battery to fail to work, external deformation, volume expansion, and even cracks.
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.
Generally, lithium battery will not leak electrolyte or any other chemical materials in normal conditions. For abnormal conditions, it leaks. There are many reasons why a lithium-ion battery might start to leak. For example, both poor manufacturing quality and improper using methods will increase the possibility of lithium battery leaking.
Today we were discussing the fact that Li-Po batteries have a leakage, that somewhere (I don't know the source) is indicated to be the 20% of the capacity in one month. So at first glance, seems that the smallest battery, as long as it can store the necessary energy to survive when there is no light.
It is not recommended to repair a leaking battery. Electrolyte inside the lithium battery is poisonous and corrosive, you’d bettery dispose leaking lithium battery to dedicated recycling station.If your lithium battery is leaking, you’d better change it as soon as possible to prevent acidic liquids from corroding your equipments.
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).
