Lithium Batteries Overheating and Explosion from Samsung Galaxy Note 7

Today, lithium batteries have become common place in the electronic device, including smart phones, laptop computers, electric vehicles, solar powered portable generator and even aircraft are widely used in lithium batteries, but recently Samsung Galaxy Note 7 flagship phone battery overheating occurred and explosions, so customers to re-examine the safety of lithium batteries.

According to US media reported last week, the US Federal Aviation Administration issued a consumer warning, recommendation on the plane do not open Note 7 or charge for it, not even in checked baggage. Many international airlines have also developed similar restrictions. In addition, the US Consumer Product Safety Commission has issued a recommendation to Note 7 to stop charging the phone.

Note 7 serious incidents, it is necessary to re-let some knowledge of lithium batteries, especially why it happened overheating or explosion?

What is a lithium battery, Why is it so popular?

Lithium battery technology is different from AA, AAA batteries etc we used (such as place on the TV remote control), the lithium battery can be recharged, in addition to the direct integration of electronic devices, lithium batteries need to rely on one of the lithium material to provide electrical power.

Since lithium batteries can store energy efficiently, it can slowly discharge, so it become a very popular battery is used in notebook computers, smart phones and other fields, like LiFePO4 battery pack.

Professor of materials science at the University of Michigan Institute of Technology, Stephen Hackney said, compare to other ancient battery technology, lithium batteries can store two to four times of the power in the same volume.
