Lithium Batteries

October 15, 2008 | Filed Under Battery | Comments Off 

Lithium batteries are batteries that use lithium metals compounds as an anode. Depending on the design and compounds used, lithium cells can produce voltages between 1.5 and 3.0 V, which is 2 times the voltage of a zinccarbon or alkaline battery. Lithium batteries are widely used in products such as portable consumer electronic devices.

Examples:
Li-Mn (manganese dioxide)
This type is used in most consumer grade batteries (~ 80% of the lithium batteries), because it is made of inexpensive materials. It is suitable for low-drain, long-life, low-cost applications due to its high energy density per both mass and volume.

Li-ion (lithium ion battery) (rechargeable)
Lithium ion batteries are commonly used in rechargeable consumer electronics, due to their excellent energy-to-weight ratios, the lack of a memory effect when recharged, and their slow loss of charge when not in use.
