The alkaline button battery is a button-like battery that is used in a wide range of small electronic devices due to its small size. In order to distinguish between the different types of button batteries, the letters "LR" are used to denote the alkaline 1.5V button battery.
What are the process characteristics of alkaline button battery?
What is the production process for alkaline button battery?
How do I choose between alkaline button battery and other batteries?
The alkaline button battery consists of a steel case, a positive ring made of manganese dioxide semiconductors, a barrel-shaped diaphragm paper and a zinc paste inside the diaphragm paper, with a raised positive terminal at one end of the steel case. The steel case of the alkaline button battery is generally nickel plated, and there are two types of nickel plating processes in common use, one is pre-nickel plated (nickel plated on the surface of the steel strip and then stamped into a steel case) and the other is post-nickel plated (the steel case is stamped with unplated steel strip and then placed in a plating bath). The other is the post-nickel plated shell (where the unplated steel strip is punched into a shell and then the shell is plated with nickel in a plating bath).
When using the post-nickel plating process, due to the small and deep diameter of the steel shell, most of the current is taken away from the mouth part during plating because of the electromagnetic effect, and only a small amount of current enters the inside of the shell, which can easily cause blind holes in the inside bottom of the shell. Therefore the nickel plating on the inside bottom of the steel case is the weakest compared to the rest of the nickel plating. During the preparation of the alkaline button battery, there is more or less air in the contact area between the positive terminal and the diaphragm paper. During the long storage period, the alkaline electrolyte in the zinc paste (which is mainly present in large quantities in the zinc paste) can easily pass through the diaphragm paper and accelerate the corrosion of the weakness of the steel case plating by the action of oxygen, thus affecting the storage life of the alkaline button battery. Button Battery's storage life.
The general consensus is that chemically, the alkaline button battery has a slight performance advantage over non-alkaline batteries. However, non-alkaline batteries are reliable, cheaper and can be used interchangeably with alkaline batteries. Electronic devices with the "alkaline only" label are often guaranteed in situations where fast, high current consumption from the battery is required. An example of this is a flash unit on a camera that needs to be charged quickly.
With the development of technology, the products of alkaline button battery are constantly improving. Guangzhou Dolphin Information Technology Co., Ltd. has different alkaline button battery and they are all more effective, reliable and consistent.
