There are so many things that run on batteries

The Li polymer cell was introduced in 1996. It rapidly bagged the acceptance of many due to its lightweight building and the detail that it was rechargeable. These gadgets parts are now being used in numerous electrically driven devices such as portable video players, portable computers and numerous rechargeable electronic apparatus. The energy density is one of the significant components of a good power cell used in latest gadgets and Li polymer cell has the largest energy density those are available in the market today. The life circuits are also longer and the degradation of such items is much slower than numerous. These attachable do have some disadvantages such as blowing up if they become overcharged, much quicker capability decrease and a longer recharge time. The two major lithium batteries accessible for buy are the ion and the polymer. The polymer is much safer than the ion cell because of the manner in which the lithium is suspended. The polymer cell suspends the lithium in a polymer gel and the lithium ion suspends the metal in an organic solvent medium. The medium material is highly inflammable different from the gel based polymer. The ion product mentioned earlier has a tendency to burst into flames if there is a short or if the electric circuit is trampled. The polymer is less likely to burst into flames in either case. An ion battery contains metal casing to house the suspended lithium while the polymer one does not need them because the lithium is housed in the gel in which it is hovering. This in turn makes the polymer a more lightweight and flexible due to the elimination of the cylindrical steel casings. With the polymer being lightweight and flexible this requests to the electronics developers and designers. These cells are often used for RC propellers. The polymer cells are furthermore mentioned to as Li-Po or Li-Poly battery. They are quickly restoring the vintage NiCad (Nickel Cadmium) and NiMH (Nickel steel, Hydride) batteries. Lithium is the lightest of all metals and has the highest energy per unit weight. It is no surprise then that lithium is quickly restoring nickel as the metal of alternative for any electronic power source. Prices can be good factor to consider and since the Li-Poly battery are much costlier than the nickel and lithium ion unit; you automatically have an idea that it is going to be a good product. When you make this purchase, you know you will get the best. It must be mentioned here that RC propellers are an area where these batteries are widely used.
