Lithium Polymer Batteries

Evolving from Lithium-ion batteries, Lithium polymer batteries offer a distinct advantage over their predecessor in terms of cost, utility, durability and flexibility. A Lithium-polymer battery can be shaped to fit in an array of devices. As cell phones become thinner, it is important for battery manufactures to develop new ways to charge these ever important devices.

Using a lithium-polymer battery allows the hobbyist to shape the battery in essentially any way they please. This allows for more freedom in designing the true power behind our projects. Another advantage of lithium polymer cells over nickel-cadmium and nickel metal hydride cells is that the rate of self-discharge is much lower.

All-Battery carries a li-polymer battery for virtually any application. With varying amperages, shapes, and sizes, you are sure to find a lithium-polymer battery for whatever device you need. Shop our huge selection today and power up your device with lithium polymer energy!

The name "lithium polymer" (LiPo) is more widespread among users of radio-controlled models, where it may indicate a single cell or a battery pack with cells connected in series or parallel.

Working principle


 LiPos work on the principle of intercalation and de-intercalation of lithium ions from a positive electrode material and a negative electrode material, with the liquid electrolyte providing a conductive medium. To prevent the electrodes from touching each other directly, a microporous separator is in between which allows only the ions and not the electrode particles to migrate from one side to the other.

Charging


The voltage of a LiPo cell depends on its chemistry and varies from about 2.7-3.0 V (discharged) to about 4.20-4.35 V (fully charged), for cells based on lithium-metal-oxides (such as LiCoO2), and around 1.8-2.0 V (discharged) to 3.6-3.8 V (charged) for those based on lithium-iron-phosphate (LiFePO4).

The exact voltage ratings should be specified in product data sheets, with the understanding that the cells should be protected by an electronic circuit that won't allow them to overcharge nor over-discharge under use.

For LiPo battery packs with cells connected in series, a specialised charger may monitor the charge on a per-cell basis so that all cells are brought to the same state of charge (SOC).

Applications


  • For LiPo bat.Radio Controlled Equipment and Airsoft.

  • Personal Electronics

  • Mobile Phones, Tablet Computers, Very Thin Laptop Computers,Portable Media Players, Wireless Controllers,Electronic Cigarettes.
  • Electric vehicles: Hyundai uses this type of Battery in some of their vehicles

Nice for beginners after here they should go and take lessons how yo make robot on robotshop.com and I recommend that u purchase arduino when u comes to 4 chapter of that blog for practical purposes and to learn and observe everything perfectly...
