The battery shelving reaction is a chemical process that occurs inside the battery during storage before the battery is not used. Similar processes also occur at the shelving phase between two discharge, but when the electrolyte component changes (as the Leclanche battery), the properties and rates of the reactive reaction occurs. The key shelving reaction caused by the corruption of the LeClanche battery is anodic corrosion.The corrosion reaction is greatly affected by the temperature, and is also affected by the microstructure and electrolyte ingredients of zinc. Corrosion can be suppressed by some measures. Previously common methods are: add a small amount of easily soluble mercury in the electrolyte to zinc surface. This allows the hydrogen level of zinc to increase, and a small amount of positive electric metal is dissolved, and the generation of the local corrosion battery is avoided.
The mercury is also influenced on zinc tissue, forming smooth and flat outer surface to reduce local corrosion, and also acting as a steady open circuit voltage. For the protection of the environment, the battery manufacturer has gradually reduced the use of mercury in the LeClanche battery, and now no longer use.
Therefore, other measures must be taken to prevent the corrosion of the LeClanche battery and other zinc-based batteries. These measures are: changing the battery manufacturing process, reducing the degree of air pollution; improving the purity of electrolyte and manganese dioxide; using a corrosion inhibitor. Corrosion inhibitors typically employ chromate or a red chromate (which can form a zinc oxide film), surfactant, surface modifier, and integrated agents.
The cathode shelving reaction is not very important, and some manganese dioxide will be consumed due to the gel reaction in the electrolyte.
