iPad Batteries
Real World Connection:
The battery used in Apple's iPad is an internal rechargeable lithium-ion polymer (LiPo) battery. This battery is very popular and is found in many laptops and other technology because of its size, power, and lifespan.
This Apple website talks about the use of LiPo's in iPads.

The LiPo contains a temperature gague, which tells when the battery is either above or below safe temperature. LiPo batteries givethe best battery life possible with the lowest total weight. They are rechargeable whenever, and they do not require a full charge. LiPo's can be charged many times, as stated in the article. An LiPo produces 3.7 volts per cell, while a AA battery only produces 1.5 volts. The more volts, the more electric potential energy, the more item use!
When a lithium-ion battery like this one is charged, the voltage increases, creating a mountain of positive charge. The electrolytes then move to the negative electrode. When the charge is unplugged, the electrolytes return to the positive electrode.
