How many specifications are there for button batteries?

Button batteries generally have two types: rechargeable and non-rechargeable: charging includes 3.6V rechargeable lithium-ion button batteries (LIR series), 3V rechargeable lithium-ion button batteries (ML or VL series); no Rechargeable batteries include 3V lithium manganese button batteries (CR series) and 1.5V alkaline zinc manganese button batteries (LR and SR series). 1. Lithium-ion button battery. A common disposable lithium-ion battery is a lithium manganese battery (code C) with a nominal voltage of 3V. The nominal voltage of lithium manganese disposable button batteries is 3V, the termination voltage is 2V, and the typical operating current is 0.1-0.2mA. It uses manganese dioxide with very stable chemical properties as the positive electrode material, and uses lithium metal with very high energy as the negative electrode material. 2. The rechargeable lithium-ion button battery is a secondary button battery and also a button battery that can be charged and discharged multiple times, with a nominal voltage: 3.7V and a charging voltage: 4.2V. 3. Silver oxide button battery. The button battery has the characteristics of long service life and large capacity. It is widely used and has the largest application volume. 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. 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. 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. Alkaline manganese button batteries use manganese dioxide for the positive electrode, zinc for the negative electrode, and potassium hydroxide for the electrolyte. The 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.
