Lithium polymer battery also abbreviated as LIP, LiPo, or Li-poly is a rechargeable battery belonging to lithium-ion technology. However, it uses polymer electrolyte rather than the liquid electrolyte.

Lithium batteries have transformed the revolution of technology by providing a sufficient energy source accompanied by a stable power supply. The need for more power increased, and this has led to the invention of the modular lithium battery systems.

With the fast pace in which technology grows and changes, most of the people are not aware of the batteries they use for their devices.

Lithium batteries are commonly used to power a wide range of devices, being found in remote control toys, computers backup batteries, calculators, hearing aids, MP3 players, laser pointers, remote car locks, thermometers and many others.

What is a lithium-ion battery? Well, it is known to be one of the best renewable sources of energy for small electric equipment or appliances and electric-powered tools.

The 18650 battery is a lithium-ion rechargeable battery, properly known as '18650 cell' that has a voltage of 3.7v and an amperage range of 1800 mAh and 3500 mAh (mili-amp-hours).

Well, what basically is a lithium battery & for purpose is it used? Everything in this world that is invented was a result of a need, without need nothing is invented, & why is that?

Both lithium and NiMH battery technologies have been around for quite some time. They are still powering devices in the modern age.

Rechargeable AA batteries are simple devices that provide a substantial amount of power to low-end devices that are conventional for human beings.

Lithium batteries are currently among the most used batteries in mobile electronics and electric vehicles. There are several reasons why these batteries are used over other battery technologies.
