How and Why Laptop Catch fire ?

The Laptop batteries is a most significant part of the lapotp. It is the part which makes the computer to be portable. The backup power of the battery is the a main feature which attract the users. But Under the right circumstances, these batteries could overheat, potentially causing burns, an explosion or a fire.

To know about the overheating of the batteries, first we must know its working. Now lets see how
battery works. A Batteries have a negatively terminal and a positively terminal. The electrochemical reaction inside the battery
generates the free electrons and increase the concentration of the electrons inside the battery. Electrons are negatively charged so they flow towards the positive terminal . So when a battery is connected to a circuit these electrons flows from negative terminal to the positive terminal to decrease the concentration of the electrons inside the cells. This means that there is flow of chargewhich in turns called as current or electricity. This flow of charge continues until there is potential difference between the terminals.

The generation of the electrons and electricity depends on the type of battery. In case of
lithium-ion battery there is a container which contains a coil of metal and flammable liquid. To manufacture a battery small pieces of metals are created which floats in the liquid. The size limitation and the number of metal pieces floating inside the liquid are basic characteristics of a good battery. The negative and positive terminals of the battery are separated by a separator to prevent them from touching each-other.

The batteries get hot while using or charging due the resistance offered to the from flow of electrons. It can make the floating pieces of the metal to puncture the separators and which can result to short-circuiting. Now here are some reasons which can further makes the battery to catch the fire:

- Rise in temperature inside battery increase the pressure and explosion can occurs.
- The sparking can make liquid to ignite.
- Rise in temperature can melt the battery and liquid can leak out.

The people in this era need small batteries with a long backup power. These needs increases the complexities of manufacturing the good batteries. So, choosing a battery from reputed and selected vendor will be safer for your computer and for you then a cheap battery.
