Button Batteries Have Been Widely Used
Because of the small size of the button cell, it has been widely used in all kinds of miniature electronic products. such as pacemakers, electronic hearing aids, electronic watches, counters, cameras and so on.
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. As shown in Figure 134. 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, most of the materials used to name, such as silver oxide batteries, button batteries, alkaline manganese batteries.
The shape of the button battery is like a small button. Button Cell The characteristic diameter is larger, the thickness is thinner application range various kinds of electronic products back-up power supply.
button battery Generally, there are two types of button battery models, which are rechargeable and not charged. The charge consists of 3.6V Rechargeable Lithium Ion button battery  (Lir series), 3V rechargeable Lithium-ion button battery (ML or VL series); non-charged including 3V lithium manganese button Battery (CR series) and 1.5V Alkaline Zinc Manganese button battery (LR and SR series); More common button batteries are used for toys and gifts on the AG3, AG10, AG13 batteries, computer motherboard batteries, Button Cell models for the CR2032 in the electronic dictionary inside the CR2025, CR2016 or SR44, SR626, etc., used in the electronic meter; the name 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, the latter two digits indicate the thickness; Typical models are: 6F22 (9V), 4f22 (6V), 15f20 (5V), 10A (9V), 11A (6V), 23A (12V), 25A (9V), 26A (6V), 27A (in), 476A (6V), 120h7d (8.4V), 2x625a (3V), etc.
Application of button 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; 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), cathode (cathode) and its electro-contact fluid. As shown in the right picture. Its appearance is stainless steel material, and as a positive, Button Cell its negative extremely stainless steel round cover, 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, most of the materials used in the name, such as silver oxide batteries, lithium batteries, alkaline manganese batteries.
Button Battery Construction
Because of the use of button batteries, the combination of the battery pack is very small, but the discharge strength is not large, used in small motors, small radio transmission DC power supply. button battery because of low cost, usually contain harmful substances, Button Cell the environmental harm is quite large, this kind of battery needs everyone's effective recovery, do not arbitrarily discarded. The button battery, as the name suggests, is a button-shaped battery
