Lithium Ion Battery

Time to Read: 1m 23s

A lithium ion battery (sometimes written as Li-ion battery or LIB) is a type of rechargeable battery commonly used for consumer electronics, as well as other applications. Lithium ions in these batteries move from the negative electrode to the positive during discharge, and from the positive electrode to the negative while recharging. Li-ion batteries come in a broad range of sizes, shapes, formats, chemistries, and charge levels. They are among the most popular rechargeable batteries for portable electronic devices because of their outstanding energy densities, durability, and cost.

A Brief History

The first lithium batteries were created by researchers at Exxon in the 1970s (until this development, most batteries utilized a nickel-cadmium chemistry). Additional research and development throughout the '70s and '80s lead to the chemical-metallic makeup currently used in lithium ion batteries, and continuing development has lead to many further updates and improvements in LIBs.

Advantages of Li-ion Batteries

Lithium ion batteries are much lighter than other energy-equivalent secondary batteries, are available in a wide variety of sizes and shapes to fit the many different devices they power, and have no "memory effect." They have high open circuit voltage compared to other battery types, allowing for increased power transfer at a lower current. LIBs also have a very slow self-discharge rate when not in use, and are more environmentally safe than other battery chemistries due to the construction of their component parts.
