A Polymer Li-ion battery (whiles Li-ion battery or LIB) is a member o a faimily o rechairgeable battery teeps in which lithium ions muive frae the negative electrode tae the positive electrode during dischairge an back when chairgin. 

Polymer Li-ion battery are popular because they have a number of important advantages over competing technologies:
Polymer Li-ion battery are generally much lighter than other types of rechargeable batteries of the same size. The electrodes of a Lithium ion battery are made of lightweight lithium and carbon. Lithium is also a highly reactive element, meaning that a lot of energy can be stored in its atomic bonds. This translates into a very high energy density for lithium-ion batteries. Here is a way to get a perspective on the energy density. A typical lithium-ion battery can store 150 watt-hours of electricity in 1 kilogram of battery. A NiMH (nickel-metal hydride) battery pack can store perhaps 100 watt-hours per kilogram, although 60 to 70 watt-hours might be more typical. A lead-acid battery can store only 25 watt-hours per kilogram. Using lead-acid technology, it takes 6 kilograms to store the same amount of energy that a 1 kilogram lithium ion battery can handle. That's a huge difference.
Polymer Li-ion battery hold their charge. A Lithium ion battery pack loses only about 5 percent of its charge per month, compared to a 20 percent loss per month for NiMH batteries.
Polymer Li-ion battery have no memory effect, which means that you do not have to completely discharge them before recharging, as with some other battery chemistries.
Lithium ion batteries can handle hundreds of charge/discharge cycles.

That is not to say that Polymer Li-ion batteries are flawless. Polymer Li-ion battery have a few disadvantages as well:
Polymer Li-ion battery start degrading as soon as they leave the factory.Lithium ion battery  will only last two or three years from the date of manufacture whether you use them or not.
Polymer Li-ion battery are extremely sensitive to high temperatures. Heat causes lithium-ion battery packs to degrade much faster than they normally would.
If you completely discharge a Polymer Li-ion battery , it is ruined.
