Button cell (button cell) also known as a button cell, refers to the size of a small button in the shape of the battery. Because of its small size, button cell has been widely used in various miniature electronic products. Diameters from 4.8mm to 30mm, thickness from 1.0mm to 7.7mm unequal; Button Cell Generally used for various types of electronic products back-up power supply, such as computer motherboards, electronic tables, electronic dictionaries, electronic scales, memory cards, remote control, electric toys, pacemakers, electronic hearing aids, counters, cameras, etc.
The button battery is light, durable, high stability, and the advantages of power lasting. Use is more limited to precision instruments.
Button batteries are also very common batteries, small size, many models. The common button cells are composed of several chemical compositions: carbon, alkaline, zinc-silver oxide, zinc-air, Button Cell lithium-manganese dioxide, nickel-cadmium rechargeable button battery, Button Cell nickel-Hydrogen rechargeable button battery, etc. If there is a distinction between a monomer and a cascade in shape.
button battery is from the shape of the battery to divide, the same corresponding battery classification has columnar batteries, square battery, different button battery parametric battery; Category button battery Generally speaking there are two kinds of charging and not charging, the charge includes 3.6V Rechargeable Lithium-ion button Battery (Lir series), 3V rechargeable Lithium-ion battery ( ML or VL series), excluding 3V lithium manganese button Battery (CR series) and 1.5V Alkaline Zinc-manganese button battery (LR and SR series);
The type of the button battery in front of the letter indicates the type of battery, the number indicates the size, the first two digits indicate the diameter, Button Cell the latter two digits indicate the thickness;
Because of its small size, button cell has been widely used in various miniature electronic products. Diameters from 4.8mm to 30mm, thickness from 1.0mm to 7.7mm unequal; Generally used for various types of electronic products back-up power supply, such as computer motherboards, electronic tables, electronic dictionaries, electronic scales, memory cards, remote control, electric toys, pacemakers, electronic hearing aids, counters, cameras, etc. Button batteries are also divided into chemical batteries and physical batteries of the two categories, its chemical battery applications are most common. They are composed of anode (cathode) agent, cathode (cathode) agent and electro-contact liquid. Its appearance is stainless steel material, and as a positive, its negative extremely stainless steel round cover, Button Cell the positive and negative between the sealing ring insulation, sealed ring with nylon, sealing ring In addition to the insulation role, but also can prevent leakage of electrolyte. Many kinds of button batteries, Button Cell most of the materials used to name, such as silver oxide batteries, button batteries, alkaline manganese batteries. Common button Cell 1 silver oxide battery
The button battery has the characteristics of long service life and large capacity, and its application is very wide. The battery is made of silver oxide as the cathode, the metal zinc powder as the cathode, the electrolyte is potassium hydroxide or sodium hydroxide. Electricity is produced by the chemical action of zinc and silver oxide. Silver oxide button battery thickness (height) of 5.4mm, 4.2mm, 3.6mm, 2.6mm, 2.1mm five specifications, with one diameter. 6mm, 9.5mm, 7.9mm, 6.8mm Four specifications. Button Cell Select one of them according to the size of their location. Its commonly used models are AG1, AG2, AG3, ag1o, AG13, SR626, etc., its model AG for the Japanese standard, SR for the International Standard Model. 2) 2 peroxide silver button battery
The battery is basically the same structure as the silver oxide button battery, the main difference being that the anode of the battery is made of silver peroxide. 3 Alkaline Manganese button cell
The battery has a large capacity, low temperature performance, the material used is cheap, low price, can meet the demand for greater current continuous discharge requirements. Button Cell The disadvantage is that the energy density is not enough and the discharge voltage is not stable enough. The cathode of the battery is manganese dioxide, the cathode is zinc, the electrolyte used potassium hydroxide, the nominal voltage of 1.5V. 4 Mercury Button Battery
