Li-Ion The Battery Of Choice

The recent trend for battery powered laptops and other portable equipment to become smaller and more power hungry has led to the creation of the lithium-ion (Li-ion) rechargeable battery.  These batteries are compact and lightweight.   The electrodes used in the Li-ion batteries are made of lightweight lithium and carbon.  When compared to the more traditional rechargeable batteries the lithium-ion batteries offer a far better performance. vtc5

The lithium-ion batters used in laptops are not the same and the primary lithium batteries used in cameras.  Li-ion technology has over the years emerged as a superior source of power for a variety of applications since its introduction in 1990.

With the added growth of the electronics and the new demands, Li-ion batteries have witnessed unprecedented popularity.  These batteries are used in laptops, iPhones, iPods, PDAs and other electronic equipment.

The energy density is what determines the size and weight of batteries.  For today’s market the goal is to minimize both the wright and size of the portable equipment.  With their significantly better volumetric energy density the Li-ion batteries give the designers the ability to create smaller, more  powerful devices.  These Li-ion batteries are not only used in consumer electronics, they are also used in aerospace, defense and automotive applications when high energy density is needed.

Li-ion cells have a much higher operating voltage than others so fewer cells are needed to build a pack.  This reduces the battery assembly costs and increases the battery reliability.

There are various reasons for the positive acceptance of the Li-ion battery in this rapidly growing market.  Benefits of using these batteries include a higher energy density, better cycle life, higher voltage per cell, great low temperature performance, simple battery management, slower self- discharge when not in use (about 5% per month). These batteries are easy to charge and they are environmentally friendly as well.

Unlike so many other batteries, the Lithium-ion batteries do not have a “memory effect”.  This means they do not have to be completely discharged before they are recharged.  These batteries also will stay new for a long time and will take hundreds of charge and discharge cycles.

Li-ion batteries can be created in various shapes and sizes so they are easy to use in all types of devices.

The Li-ion batteries do have one flaw.  They have the ability to burst into flames.  This happens very rarely, perhaps a couple battery packs in a million.  A fire may occur if the coating on the battery is punctured or if the battery is damaged and a short occurs.  You can lower the fire risk by not storing your batteries at high temperatures and by not overcharging your batteries.

Li-ion batteries are the most energetic and powerful batteries in use today and you cannot go wrong using them.  Their lack of memory effect makes the Li-ion battery all the more attractive to consumers.
