The first letter in the IEC standard system identifies the battery’s chemical composition. 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. Lithium-ion batteries do not contain metallic lithium. Note that disposable primary lithium batteries must be distinguished from secondary lithium-ion or lithium-polymer, which are rechargeable batteries. These types of batteries are also referred to as lithium-metal batteries. Lithium-based primary cells are batteries that have metallic lithium as an anode. The long-lasting function of these batteries has been verified at all operating temperatures under low-load discharge conditions. The stability is the result of the combination of lithium and manganese dioxide. Its weight is 11 grams.īecause the CR2 batteries are chemically very stable, they still have 90% of their original capacity even after 10 years. Dimensions, Weight and Capacity of CR2 BatteryĬR2 batteries have a nominal diameter of 15.6 millimeters. They’re usually button top, and are primary (non-rechargeable) batteries. The fundamental principle in an electrochemical cell is spontaneous redox reactions in two electrodes separated by an electrolyte, which is a substance that is ionic conductive and electrically insulated.Ī 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. A typical battery consists of one or more voltaic cells. This then provides a source of electromotive force to enable currents to flow in electric and electronic circuits. It converts stored chemical energy into electrical energy through an electrochemical process. Li (s) + Mn IVO 2(s) ⇌ Mn IIIO 2(Li +) Īn electric battery is essentially a source of DC electrical energy. 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. In general, lithium metal batteries, such as the CR2 battery, have a very high energy density, double that of premium alkaline batteries.
