In the campaign, a mobile phone or smartphone can be used for a variety of purposes: call for help, find a way to a safe place, talk with loved ones. But even after the power source is completely discharged and the mobile device stops working for its intended purpose, lithium batteries of a mobile phone or smartphone can be used as a kind of lifebuoy for producing fire.
Making fire with a lithium battery of a mobile phone or smartphone, three different ways to get a spark from a battery.
Thanks to powerful lithium batteries with valuable chemical components, personal mobile electronic devices such as mobile phones, smartphones, tablets and navigation systems can be used to make fire. Moreover, long after they cease to function. Thanks to lithium ions, batteries have such a high energy density that when they are closed, their contents begin to heat up and then burn with the appearance of a flame.
When you try to get to the battery, you will encounter some difficulties. This is no coincidence. Manufacturers are guided by safety concerns. After you still remove the battery from the mobile device, try to use the remaining charge in it, connecting its positive and negative terminals to each other using a knife or other metal object equipped with a handle that does not conduct electric current.
The spark that has appeared should be enough for the tinder to smoke. However, if you are careless, an undesirable side effect is also possible – a rather strong electric shock. If this technique does not work, lay the battery on the ground and pierce it with the tip of a knife. In this case, the protection is impaired and a short circuit occurs in the battery. It will cause a sharp short-term release of energy.
How to make fire with the lithium battery of a mobile phone, smartphone or tablet.
1. To get to the battery, remove the back cover from the phone.
2. Remove the battery.
3. There are three different ways to trigger a spark:
Connect the positive and negative terminals of the battery to each other.
Pierce the surface of the battery with a knife so that lithium is connected to the air.
Pour water onto the lithium battery. This will cause a mini explosion.
A similar effect, which will manifest itself even stronger, in the form of a microexplosion, can be caused by pouring water on the battery. The liquid breaks the protection circuit, which prevents the lithium battery from contacting each other. This leads to a peak voltage..
Move away quickly from the battery in this condition. A flame will emit, and in addition, toxic compounds will be released. Fire caused by lithium ions is dangerous, toxic, and difficult to extinguish. Therefore, the described method should be resorted to only in the most extreme case. When it comes to survival. Do not try to resort to it in other conditions..
