The CR123 battery is a type of lithium battery commonly used in various electronic devices. It is a non-rechargeable battery known for its high capacity and stable voltage. The “CR” in CR123 stands for the cylindrical lithium battery, and the “123” stands for its size—specifically, it has a diameter of about 17 millimeters and a length of about 34.5 millimeters.
CR123 batteries are often used in devices such as cameras, flashlights, smoke detectors, and other small electronic devices. They are known for their long shelf life and ability to provide consistent energy output over their lifetime. Remember that CR123 batteries are non-rechargeable, so once they are used up, they should be disposed of properly and replaced with new ones.
Chemistry of cr123 battery
The CR123 battery, also known as the CR123A, runs on lithium chemistry. Let’s dig deeper into the CR123 battery pack:
1. Lithium Anodes: The anode (negative electrode) of a CR123 battery is usually made of lithium metal or lithium alloy. During the discharge, lithium ions move through the electrolyte from the anode to the cathode, carrying an electric current.
2. Cathode materials: The cathode (positive electrode) of a CR123 battery is usually a mixture of lithium manganese dioxide (LiMnO2) or lithium iron disulfide (LiFeS2) These materials are chosen because of their ability to absorb lithium ions well in the discharge.
Lithium Manganese Dioxide (LiMnO2): This cathode material is commonly used in CR123 batteries. It provides high stability and excellent performance at different temperatures.
Lithium Iron Disulfide (LiFeS2): Some CR123 batteries can use this new cathode material, which also provides high power and is known for its durability and durability
3. Separator: The separation in a CR123 battery is usually a thin, porous layer that prevents direct contact between the anode and cathode and allows lithium ions to leak in. This separation is necessary to maintain the integrity and safety of the battery.
4. Electrolyte composition: The electrolyte is a conducting solvent that facilitates the movement of lithium ions between the anode and cathode. It also plays an important role in the overall performance of the battery. Typically, the electrolyte in a CR123 battery is a lithium salt dissolved in a solvent.
Working Principle: During the discharge, lithium ions move through the electrolyte from the anode to the cathode, producing an electric current. This flow of electrons energizes the coupling device. During discharge, the chemical reactions of the anode and cathode are reversible, so that the battery is used until the raw materials are exhausted or depleted.
It is important to note that the CR123 battery is non-rechargeable. Attempting to recharge could pose a safety hazard, as non-rechargeable lithium batteries are not chemically engineered to withstand the stress level of the charger.
