lithium-ion polymer, lithium-ion polymer, or more commonly lithium polymer batteries (abbreviated Li-poly, Li-Pol, LiPo, LIP, PLI or lip) are rechargeable batteries (secondary cells). Normally, cells are composed of several identical cells plus secondary parallel to increase the capacity of the existing landfill.

Lithium ion batteries have taken over the portable electronics industry in recent years. For each unit of energy they contain, they are lighter, cheaper and smaller than other types of batteries. They do not suffer from the "memory" effect that gave nickel batteries a bad reputation, they contain relatively few toxic metals and are fairly simple to recycle.

But, in the past year, several battery manufacturers pushed the limits of energy density in Li-ion too far. Li-ion batteries use organic solvents to suspend the lithium ions. In situations where the structure of the battery is compromised, the solvent can ignite and vent the battery under pressure. The result is a fireworks display of dangerous and toxic as you can see in a video at the end of this article.

In reply to the dangers of packaging more power into a rechargeable Li-ion batteries, portable electronics manufacturers are turning to lithium polymer batteries. You can view abbreviated Li-Po (yes, like the Chinese poet) or Li-polymer, or you can see in its complete form and prolonged lithium-ion polymer battery, they all mean the same thing.

Lithium Polymer Battery Advantages and disadvantages

Advantages

flexible form factor - The lithium polymer batteries can be manufactured in a wide range of shapes and sizes

Lightweight - The lithium polymer batteries do not require that the metal casings that are required by lithium-ion

Safe - The polymer electrolyte used in lithium polymer is not flammable

Disadvantages:

More expensive than lithium-ion

Slightly smaller than the enery density lithium-ion

Slightly less effective cycles than the lithium-ion

Applications

A distinct advantage of Li-poly cells is that manufacturers can shape the battery almost but please, which may be important to mobile phone manufacturers are constantly working the phones smaller, thinner and lighter .

3-Cell LiPo batteries for RC-poly-modelsLi are more in favor in the world of radio controlled airplanes, cars and radio controlled, which benefits both lower weight and increased the operating time can be a justification sufficient for the price. Some airsoft gun owners have turned to LiPo batteries for the reasons above and the increased rate of fire they provide. However, shippers lithium-polymer-specific are necessary to prevent fire and explosion. Explosions can also occur if the battery is short-circuited, that huge current passes through the cell in an instant. The amateur radio-command to take special precautions to ensure their cables are properly connected and insulated. In addition fires can occur if the cell or block is pierced. car batteries are often radio-controlled protected by durable plastic enclosures to avoid perforation. motor speed controls are designed electronics used to prevent excessive discharge and subsequent damage to the battery. This is achieved using a low voltage cutoff (LVC) setting that is adjusted to maintain a higher voltage than the cell (typically) 3 V per cell.

Li-Poly batteries are also gaining ground in PDAs and laptops, such as Apple MacBook, MacBook Pro and MacBook Air, Amazon's Kindle, Lenovo Thinkpad X300 and Ultrabay Batteries, series OQO handheld computers The HP Mini and the Dell products with D-bay batteries. They can be found in small digital music devices such as iPods and other MP3 players and gaming equipment like Sony's PlayStation.
