The Best Lithium Batteries and Their Features

Lithium batteries are all the rage now, and they have certainly unseated the good old alkaline battery for some very good reason. Being able to last more than twice as long means a much better value for money. Sure, they are slightly more pricy than their alkaline counterparts, but this price comes at a distinct advantage of having your appliance last for much, much longer than usual. This length can sometimes reach 3 – 5 times the predicted use time. This article will discuss some of the great features of lithium batteries and why they are taking the electronic mobile world by storm.

Firstly, what is the difference? Well simply put, in a lithium battery, lithium metal or compounds are used as the battery's anode and this means that it can produce up to and over 4.0V – which is much more than zinc carbon and alkaline batteries. For consumer use, the most common incarnation of the lithium battery is the one that uses a metallic lithium as the anode and the cathode is placed in the hands of manganese dioxide. Salt of lithium is dissolved in the battery in an organic solvent. Because of their high energy density, these batteries have found their applications in many long life, low drain critical devices for both consumers and the medical industries. A good example is that the medical industry has seen great success in switching their pace makers over to using lithium batteries.

Small lithium batteries are the best incarnations of this technology because it is able to power effectively devices like PDA's, watches, calculators, small computers and remotes quite effectively over a long period of time. Their high energy density and their energy to weight ratio makes it an excellent choice to ensure that an appliance will run for a very long time without worry of swapping or constantly charging the battery. The most common one is the small lithium battery – resembling nothing more than a coin, this 3 V variety is made up of lithium and manganese and is about 20 mm in diameter and no thicker than a small coin. Not only limited to these small electrical appliances, lithium batteries are also great for quick drain high energy devices like digital cameras, as they can maintain a higher voltage for a longer period of time. Their recharge times are also mainly shorter than alkaline rechargeable batteries.

Many major manufacturers are turning their attention to improving the lithium technology and extend the life of the battery to longer periods and shoreer recharge times. As appliances get more and more complicated as the years go by, these great lithium batteries need to adapt as well. More complex chemical combinations and use of new space aged metals will allow the battery life to extend even further. Who knows, in the near future, we might have a veritable nuclear power plant in the palm of our hands. Technology has always been able to surprise us. For now, the world is quite comfortable with some of the best lithium batteries out there.
