Why does the cell phone battery explode? In general, few people will associate cell phone explosions with batteries, but in fact, the real source of cell phone explosions is cell phone batteries. There are two factors in this, one is the problem of the product itself; the other is the result of improper use. Now let's put these two factors down for a while, let's talk about why the battery will explode? The quality of the mobile phone battery itself is very important Well, after understanding the principle of cell phone battery explosion, the two explosion factors introduced earlier can be understood by our capacity, so in simple terms, it is mainly the following three points: The quality problem of the battery itself: mainly due to internal defects of the battery, excessive impurities of raw materials, unqualified processes, and inconsistent design of battery safety protection. Long-term overcharging of the battery: Under the condition of long-term charging, over-charging and over-current will also cause high temperature and high pressure, which may cause hidden dangers. Moreover, lithium batteries may instantaneously discharge under a special temperature, humidity and poor contact conditions to generate a large amount of current, causing spontaneous combustion or explosion. Battery short: When the phone is in a high temperature state, or is subjected to impact, metal friction, etc., it may cause a short circuit in the battery, causing an explosion. How to avoid an explosion Using a quality charger or original charger, the charging process of the lithium battery is generally constant current, and then constant pressure, in order to ensure that the mobile phone battery is not easy to overcharge, some mobile phone chargers will have self-discharge function after full charge. Just to avoid overcharging. Use the original battery, you must avoid the use of cottage batteries, inferior batteries, because the general appearance of the battery will be covered with a layer of security film, when the pressure inside the battery reaches a certain level, it will burst the safety film release pressure, and the battery itself will not explode . However, inferior batteries may not have a safety film. The price of hundreds of brand batteries and 30 to 40 pieces is not only a difference in price. Do not charge the mobile phone at low temperature. When the temperature is below 0 °C, the charged power will be significantly lower than the normal power, which will result in insufficient balance of positive and negative reactions, resulting in crystal precipitation of excess lithium ions. , causing the diaphragm to be pierced, causing a short circuit inside the battery to cause an explosion. Do not put your phone in a place where it is not easy to dissipate heat while charging. Some people are used to charging the phone in the bed before going to bed. This is very dangerous. When charging, it is found that the mobile phone should be powered off immediately, and you don't need to use the mobile phone immediately after the power is turned off. Do not use the mobile phone to make calls, etc. If the battery is deformed or drummed, do not use it. Do not place the battery in a high temperature environment, and do not violently strike or squash it, so avoid sun exposure when charging. Point the side of the phone with the screen towards you. Careful friends may find that the explosion of the phone, the damage is basically the back, especially the bottom of the battery, because it is the seam of the packaging battery, the most vulnerable. If we put the screen side towards ourselves when we put the phone, even the explosion will also be shot outwards.

Some foreign media reported that an American user woke up in the morning and found that the iPhone4, which was placed on the bedside, suddenly smoked and sizzled. She immediately wrapped the cigarette in her notebook bag and threw it into the sink. There was no accident. This is a real case. This is not the first case of cell phone battery explosion. In Baidu, the search for "mobile phone battery explosion" is a keyword search. There are 1,460,000 related searches, which have to be shocked.
