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.
