Alkaline battery application

The history of alkaline power battery application is also a history of alkaline battery development. Based on the zinc-manganese dry battery in the 1950s, the alkaline zinc-manganese battery is not only higher than the zinc-manganese dry battery but also has a wide operating temperature range. It improves storage performance and leak-proof performance and is more suitable for continuous discharge of high current. In the 1980s, people's environmental awareness increased, and mercury-free alkaline batteries entered the market in the mid-1990s. Since the 1960s, extensive research has been carried out on rechargeable alkaline zinc-manganese secondary batteries, but due to its shallow depth of discharge and short cycle life, it has not yet been commercialized.

Whether in the civilian sector or in the military sector, alkaline battery applications are primarily used as portable power sources. The advantages described below allow alkaline batteries to be used in the following areas:

1. High current characteristics: It can be used in equipment that requires large current supply, such as cameras, cameras, electric toys, tape recorders, etc.

2. High capacity and low internal resistance characteristics: can provide a more stable working voltage and longer working time, suitable for remote control, instrumentation, handheld terminals and so on.

3. Excellent high-temperature discharge performance and high operating voltage characteristics under medium current discharge: make alkaline batteries have advantages in certain special fields, such as downhole operation and high-temperature working environment.

4. Excellent storage performance and leak-proof performance: making it a necessity in military communication equipment, such as supporting power for tactical radio, field telephone, terminal equipment, instrumentation, etc. Since alkaline batteries can be stored for three years and can be used for up to five years, they can be used as storage batteries for production, life and military purposes.

At present, the role of alkaline batteries is mainly to replace the market of raw zinc-manganese dry batteries. In developed countries, the basic replacement has been basically achieved, and China is also in the process. From the future development prospects, future research on alkaline batteries mainly focuses on high-power heavy-duty discharge performance, battery capacity, and storage life improvement. From the technical requirements, there is also mercury-free production and use rechargeable. Of course, there are also product requirements for improving multiple performances at the same time. As long as the price allows, there are examples of design solutions in this area. For example, there is a high-power battery in the alkaline battery series, which can work for 67 minutes at 1000mA. For the dry battery, it belongs to the high power category. The ordinary alkaline dry battery can provide a very limited capacity under this current condition, which is unable to meet the requirement of one hour of operation.
