According to the industry standards (GB/T 31484-2015), the maximum leakage current allowed in a battery system is defined as the threshold to classify soft and hard SC faults, which is C/3.7 , where C refers to battery nominal capacity.
Battery leakage is the escape of chemicals, such as electrolytes, within an electric battery due to generation of pathways to the outside environment caused by factory or design defects, excessive gas generation, or physical damage to the 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.
In the presence of electrolyte leakage, not only will the content of the battery electrolyte decrease but the electrolyte will also continue to react with various components of air , resulting in decomposition and a change in the electrolyte composition.
The leakage of battery chemical often causes destructive corrosion to the associated equipment and may pose a health hazard. Zinc–carbon batteries were the first commercially available battery type and are still somewhat frequently used, although they have largely been replaced by the similarly composed alkaline battery.
The byproducts of the leakage may include manganese hydroxide, zinc ammonium chloride, ammonia, zinc chloride, zinc oxide, water and starch. This combination of materials is corrosive to metals, such as those of the battery contacts and surrounding circuitry.
