What Are The Different Types of Rechargeable Battery Chemistries?



Batteries in portable consumer devices ( laptop batteries, notebook batteries, camcorder batteries, cell phone batteries, digital camera batteries, cordless phone batteries, etc.) are principally made using either Lithium Ion (Li-Ion) or Lithium Polymer (Li-Polymer) technologies. Each type of rechargeable battery technology has its own unique characteristics:



Li-Ion: Li-Ion has quickly become the emerging standard for portable power in consumer devices. Li-Ion batteries produce the same energy as NiMH batteries but weigh approximately 35% less. This is crucial in applications such as camcorders or notebook computers, where the battery makes up a significant portion of the device's weight. Another reason Li-Ion batteries have become so popular is that they do not suffer from the memory effect at all. They are also better for the environment because they do not contain toxic materials such as Cadmium or Mercury.



Li-Polymer: This is a newer type of Li-Ion battery. It uses a solid polymer electrolyte that looks like a plastic film. It contains a gelled electrolyte which is less susceptible to leaking and uses a bag type enclosure rather than a rigid metal case. This leads to a lighter and thinner battery and it is considered safer because the gelled electrolyte is less likely to leak. It is also more resistant to overcharge.
