Mercury free raw materials and spare parts for alkaline manganese battery

In order to promote the mercury free process of alkaline manganese battery, we should pay solid attention to the construction of several bases. The quality of EMD for mercury free alkaline manganese battery needs to be further improved, especially the content of heavy metal impurities needs to be further reduced, and some efforts should be made to improve the battery potential and high voltage discharge capacity.

Many of the micro powder graphite used in alkaline manganese dioxide batteries are processed from squamous graphite, which contains high contents of Fe, Cu and other elements. Without effective control measures and detection means, the production of mercury free battery with this graphite can lead to major quality accidents.

If mercury free zinc powder has not yet passed the test, we must start with the selection of high-quality zinc materials, and we must also study the appropriate processing methods. In Bi CA zinc alloy with Ca instead of Al is more conducive to reduce the chronic short circuit during the storage period of mercury free alkaline manganese dioxide battery. Selecting zinc powder with low dependence of gas evolution on discharge depth is an important measure to solve the storage and leakage resistance of mercury free battery.

The performance of diaphragm for alkaline manganese dioxide battery needs to be further improved, the density and uniformity should be improved, and the retardation should be increased. The diaphragm winding technology provided by Korea is spiral winding method. In order to meet the requirements of mercury free, it is recommended to appropriately adjust the winding angle to increase the number of effective layers. Reducing the thickness of diaphragm paper and increasing the number of winding layers is also a tendency of the international alkali manganese battery industry.

Traditional zinc paste thickeners such as CMC have poor stability due to the use of mercury free zinc powder, which can not meet the requirements of mercury free batteries. In order to improve the anti vibration performance and storage performance of mercury free alkaline manganese battery, it is recommended to select zinc paste thickeners with high viscosity and good stability such as PA and PA Na, and select the appropriate ratio. The performance of the battery can obtain ideal results. The standardization of spare parts of alkaline manganese battery is the basic condition for the realization of mercury free alkaline manganese battery. It is very important to establish several alkali manganese battery spare parts bases and strengthen the quality control of spare parts to improve the quality of alkali manganese battery and realize mercury free alkali manganese battery.
