IATA Class 9 Lithium Batteries

A battery contains two or more cells that are electrically connected together and fitted with devices necessary for use, such as a case, terminals, and protective devices. A battery cell is defined as a single encased electrochemical unit, with one positive and one negative electrode, which exhibits a voltage differential across its two terminals. Batteries are commonly transported by air, alone, or encased in electronic devices.

The term lithium battery refers to a family of batteries with different chemistries, comprising many types of cathodes and electrolytes. They differ from other batteries in the high charge density, which means they have a long lifespan, and high cost per unit. Lithium batteries are separated into two main categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are generally primary (non-rechargeable) batteries that have lithium metal or lithium compounds as an anode. They are used to power devices such as watches, calculators, cameras, and temperature data loggers. Lithium ion batteries are secondary (rechargeable) batteries in which the lithium ions move between the anode and the cathode. These batteries are commonly used in consumer electronics such as mobile phones and laptop computers.
