A CR2 battery is a 3V lithium-metal-based cylindrical cell that can be used to power devices such as alarm system motion detectors, flashlights, cameras, monitors, computer memory, toys, games, LED lights, and much more. They’re usually button top, and are primary (non-rechargeable) batteries. Dimensions, Weight and Capacity of CR2 Battery CR2 batteries have a nominal diameter of 15.6 millimeters. The overall height is 27 millimeters. Its weight is 11 grams. Because the CR2 batteries are chemically very stable, they still have 90% of their original capacity even after 10 years. The stability is the result of the combination of lithium and manganese dioxide. The long-lasting function of these batteries has been verified at all operating temperatures under low-load discharge conditions. Lithium Metal BatteriesEven though a wide range of types of batteries exists with different combinations of materials, all of them use the same principle of the oxidation-reduction reaction. In an electrochemical cell, spontaneous redox reactions take place in two electrodes separated by an electrolyte, which is a substance that is ionic conductive and electrically insulated. The redox reaction is a chemical reaction that produces a change in the oxidation states of the atoms involved. Electrons are transferred from one element to another. As a result, the donor element, which is the anode, is oxidized (loses electrons), and the receiver element, the cathode, is reduced (gains electrons).
Lithium-based primary cells are batteries that have metallic lithium as an anode. These types of batteries are also referred to as lithium-metal batteries. Note that disposable primary lithium batteries must be distinguished from secondary lithium-ion or lithium-polymer, which are rechargeable batteries. Lithium-ion batteries do not contain metallic lithium. In general, lithium metal batteries, such as the CR2 battery, have a very high energy density, double that of premium alkaline batteries. They also have high cell voltage, flat discharge characteristic, low self-discharge, a very long operating life (15 to 20 years for lithium thionyl chloride), and a wide operating temperature range ( -60 ° C to +85 ° C for lithium-sulfur dioxide), excellent durability, and small cell size.An electric battery is essentially a source of DC electrical energy. It converts stored chemical energy into electrical energy through an electrochemical process. This then provides a source of electromotive force to enable currents to flow in electric and electronic circuits. A typical battery consists of one or more voltaic cells. Batteries gradually self-discharge even if not connected and delivering current. This is due to non-current-producing “side” chemical reactions that occur within the cell even when no load is applied.
If we go into detail, batteries convert chemical energy directly to electrical energy. For example, chemical energy can be stored in Zn or Li, which are high-energy metals because they are not stabilized by d-electron bonding, unlike transition metals. A CR2 battery is a 3V lithium-metal-based cylindrical cell that can be used to power devices such as alarm system motion detectors, flashlights, cameras, monitors, computer memory, toys, games, LED lights, and much more. They’re usually button top, and are primary (non-rechargeable) batteries. Primary lithium batteries have the lowest self-discharge rate hence the longest available shelf time, up to 10 years, and in temperatures up to 70. The first letter in the IEC standard system identifies the battery’s chemical composition. C is for lithium metal batteries (as CR2032). The characteristics that make lithium an exceptional electrode material for high energy density batteries include low electrode potential and very high conductivity. It is soft and malleable and can be extruded into thin foils. When the circuit is closed, the stronger attraction for the electrons by the cathode (e.g. manganese dioxide in primary lithium batteries) will pull the electrons from the anode (e.g. lithium metal) through the wire in the circuit to the cathode electrode. This battery chemical reaction, this flow of electrons through the wire, is electricity. In a primary lithium battery, the negative electrode is metallic lithium, and the positive electrode is high-density manganese dioxide (MnO 2). The electrolyte in Li/MnO 2 cells is an organic solvent mixture into which an alkali metal salt is dissolved. Li + ions go into the solution and diffuse through the electrolyte and separator to the cathode. Electrons travel through the external circuit and arrive at the cathode where MnO 2, Li + ions, and electrons combine. The MnO 2 is reduced from the tetravalent to the trivalent state. The solid discharge reaction product remains in the cathode. No gases are evolved during discharge to cause a pressurized condition
