Zinc manganese battery is the most common batteries in daily life and belong to international standardized products. Like 18650 battery, the zinc manganese battery has a simple structure, a long storage time, is easy to carry, is less affected by external humidity, temperature and other environments, and has stable and reliable performance.
1. Zinc manganese battery types and comparison
The zinc manganese battery is a primary battery that uses manganese dioxide as the cathode and zinc as the anode to generate current through redox reactions. It is widely used in various life scenes. The common models are number 5 and number 7 batteries.
Compared with other primary batteries, zinc manganese battery has the advantages of high power, good discharge performance, high battery capacity, and long storage life. According to different electrolytes and electrode structures, zinc manganese battery can be divided into carbon zinc manganese battery and alkaline zinc manganese battery.

From the perspective of upstream raw materials in the industrial chain, the main raw materials for zinc manganese battery is processed from some non-ferrous metals (copper, zinc). According to statistics, in 2021, China's nonferrous metals industry will overcome the negative impact of repeated epidemics, grasp the opportunities of recovery in the Chinese and international markets, and the overall operation of the industry will be stable.
3. Analysis of current situation of zinc manganese battery industry
Global
From the perspective of the global alkaline manganese battery market size, according to statistics, due to the impact of the new crown epidemic, the import and export of alkaline manganese batteries will decrease in 2020-2021, and the growth of the market scale will be hindered.
In 2021, the global alkaline manganese battery market size will be US$7.76 billion, a year-on-year increase of 1.3%. As the impact of the epidemic gradually weakens, the growth rate of the global lithium vs alkaline batteries market will return to normal levels. It is estimated that the global alkaline manganese battery market will reach US$10.86 billion in 2028, with a compound growth rate of 4.9% from 2021 to 2028.
China
With the development of China's zinc-manganese industry, internationally renowned brand companies have gradually withdrawn from the production process due to the impact of high local labor and raw material costs. China has become the world's largest zinc manganese battery production base.
Zinc manganese batteries, lithium primary batteries, and storage batteries are all primary batteries. According to statistics, the output of primary batteries and battery packs in China will reach 41.12 billion in 2021, a year-on-year increase of 0.7%. It is estimated that the output of primary batteries and primary battery packs in China will exceed 42 billion in 2024.
In terms of import and export, China's alkaline manganese batteries are mainly exported. According to statistics, China will export 14.51 billion alkaline zinc manganese battery in 2021, a year-on-year increase of 10.2%, and the export value exceeds US$1.3 billion, a year-on-year increase of 9.4%.
4. Future development trend of zinc manganese battery industry
Compared carbon zinc battery vs alkaline, the counter electrode structure of alkaline zinc manganese battery increases the relative area between the cathode and anode of the battery. The battery capacity and discharge time of the alkaline manganese battery are 3-7 times that of the same type of carbon manganese battery. In terms of operating temperature, alkaline manganese batteries are more resistant to low temperatures, and are more suitable for high-current discharge and stable operating voltage scenarios.
In addition, the alkaline manganese battery is mercury-free, cadmium-free, lead-free, green and environmentally friendly, and will not cause heavy metal pollution to the environment. In 2021, China will export 14.505/14.499 billion alkaline zinc manganese battery and carbon zinc manganese battery respectively. The proportion of alkaline zinc manganese battery in the export structure of zinc-manganese batteries continues to increase, and carbon-manganese batteries will gradually be replaced by alkaline-manganese batteries in the future.
The electric toy market grew moderately, and the demand for zinc manganese battery was stable. Toys are divided into non-powered toys and electric toys according to different powers. Among them, electric toys are very popular among children because of their sports and controllable functions. According to PND data, the global toy market sales will reach US$104.2 billion in 2021, a year-on-year increase of 9.7%, and sales will hit a record high.
In terms of the Chinese market, according to data from the China Toy and Baby Products Association, the sales of the Chinese toy market will reach 85.46 billion RMB in 2021, a year-on-year increase of 9.6%. It is expected that the retail sales will reach 91.4 billion RMB in 2022. The global and Chinese toy market as a whole showed a moderate growth trend.
The update and iteration of home appliances has brought about incremental demand for zinc manganese battery. Zinc manganese battery is an important part of home appliances. The release of demand for home appliances will further promote the increase in zinc manganese battery. Secondly, the upgrading of the product structure of home appliances, especially the requirements for environmental protection, can promote the development of alkaline zinc manganese battery with higher environmental protection and performance requirements.
