What Kind of Battery Is an Alkaline Button Battery?

alkaline button

Alkaline button batteries (LR batteries) are small primary batteries that use manganese dioxide for the positive electrode, zinc for the negative electrode, and alkaline aqueous solution for the electrolyte. It is cost-effective and widely used in toys and medical appliances. At present, some major brands in the market, such as Sony, Panasonic, GP and other alkaline button batteries, protect the environment, and the mercury usage rate is 0%. The MICROPOWER brand button battery produced by our company is also environmentally friendly. It has passed ROHS certification and has a mercury content of 0%.

#1-Alkaline Button Batteries Have Very Good Characteristics, as Follows:

battery characteristics

Cost-effective: the cathode material uses relatively cheap manganese dioxide, and the anode uses zinc. Compared with silver oxide button batteries, alkaline button batteries are more cost-effective.

Superior discharge stability and heavy-load pulse characteristics: Even if it is an instantaneous high-current discharge, a stable discharge voltage can be obtained.

Superior liquid leakage resistance: Due to its own structural characteristics, alkaline button batteries have a very low probability of liquid leakage, achieving superior liquid leakage resistance.

The self-discharge rate is very small: it is stored at 20 degrees Celsius for half a year, and the discharge duration after 1 year hardly changes.

#2-What Is the Main Purpose of Alkaline Button Batteries?

purpose of alkaline button batteries

Medical equipment, electronic thermometers, anti-theft alarms, toys, LED lamps and other low-power electrical appliances.

#3-What Is the Principle of Alkaline Manganese Button Battery?

principle of alkaline button battery

The main material of the positive electrode is manganese dioxide, and the active material of the negative electrode uses special treated fine zinc powder. In addition, KOH (potassium hydroxide) can be used as an electrolyte, which can stabilize the supply voltage for a long time. The discharge reaction of the battery is:

The electromotive force shows about 1.50V, and the battery voltage shows a stable and gentle voltage characteristic to the end of discharge, and its characteristic is that the impedance characteristic during the discharge process is also very low.
