Analysis of the types of button batteries

1. Silver oxide battery. The button battery has the characteristics of long service life and large capacity. It is widely used and has the greatest application capacity. This kind of battery uses silver oxide as the positive electrode, metal zinc powder as the negative electrode, and the electrolyte is potassium hydroxide or sodium hydroxide. Electricity emerges through the chemical use of zinc and silver oxide. The thickness (height) of the silver oxide button battery has five specifications of 5.4mm, 4.2mm, 3.6mm, 2.6mm, and 2.1mm, and its diameter has four specifications of 11.6mm, 9.5mm, 7.9mm, and 6.8mm. When choosing, choose one of them according to the size of its location. The commonly used models are AG1, AG2, AG3, AG1O, AG13, SR626, etc. The model AG is the Japanese standard, and the SR is the international standard model. 2. Silver peroxide button battery. The structure of this battery is basically the same as that of silver oxide button battery. The important difference is that the anode (glen pole) of the battery is made of silver peroxide. 3. Hammer button battery, which has the characteristics of high energy density, good storage performance, small self-discharge and long life. The disadvantage is that the internal resistance of the battery is relatively large. The positive electrode of the battery is made of manganese dioxide or iron disulfide as raw materials, the negative electrode is a hammer, and its electrolyte is organic matter. The nominal voltage of the Li/MnO hammer battery is 2.8V, and the nominal voltage of the Li(CF)n hammer battery is 3V. 4. Alkaline manganese button battery. The battery has large capacity, excellent low temperature performance, cheap materials and low price, and can meet the requirements of continuous discharge with a large current. The disadvantage is that the energy density is not enough and the discharge voltage is not stable enough. The battery uses manganese dioxide for the positive electrode, zinc for the negative electrode, and potassium hydroxide for the electrolyte. Its nominal voltage is 1.5V. 5. Mercury button batteries, also known as mercury batteries, have the characteristics of being able to be used under high temperature conditions, long-term storage, stable discharge voltage, and good mechanical properties. But its low temperature characteristics are not good. The positive electrode of the battery is mercury, the negative electrode is zinc, and the electrolyte can be potassium hydroxide or sodium hydroxide. Its nominal voltage is 1.35V.
