Why will the battery drum and explode?

As the saying goes, the most gathering of Jin Jiu Silver 10. The mobile phone industry will be the most gathering these two months; but the new machine is naturally released, and there is also . Quality issues.

For example, recent media reports, publishing only one week of iPhone8 exploded during charging. Although Apple said that it is investigating, we will talk about the mobile phone battery before this, and why will I explode?. First, why the battery will take the truth, although this is a keyword of "iPhone8Plus explosion", but if you have seen the portraits and videos of these trusters, you will find this Accurately describe-iPhone8plus battery drum bag, the body is cracking from the internal squeeze.

As for you say it will not explode: there is this possibility, but it has not happened. Next, let's take the mobile phone battery. Why drums, after all, the functional battery drum bag is really all.

Generally speaking, we often use the lithium-ion polymer battery when charge and discharge, it will be born in the battery. It is usually absorbed during discharge, and so the battery is slightly burden is permitted (of course, iPhone8plus drums so can't wash ). So where is this excessive blotle, which is generally divided into both endome factors and.

In terms of destruction, there is no protective board inside the product, the positive and negative pole distribution is unreasonable, the basis of the alkali (electrolyte) is not average, etc., will become the cause of battery drums. Detabate, the current structure of the lithium-ion battery is shown in the figure: positive, negative electrode, intermediate electrolyte.

Tens of thousands of electrons are started from the negative electrode, after the electrolyte, reaching the positive electrode, there is current. Charging process and discharge opposite. However, when the charging conditions are not suitable, such as the voltage current is too large, it will cause the battery to heat the battery, so that the internal material analysis of the battery will be born with a gas body.

There are also other originals that will make the battery, such as the battery itself, there is a problem, there is impurities inside, or the electrolyte leakage. The external is in fact, we are also familiar, non-original charging heads and wires cause too high, the charging time is too long, the external temperature is too high, strong light direct, long-term fast and high pressure charging, etc. Second, how far is it from the battery explosion, how far is the explosion from the battery drum, which may be a key topic to interpret.

Take the iPhone8Plus of an accident as an example, the battery of the iPhone8Plus is locked in the machine. When IPHONE battery drums, it is actually a part of the battery shell locked. Once the gas is too much, the outer casing will not be exploded.

Similarly, the drum bag is caused by fever, and when the heat of the heat is too much, it will produce spontaneous combustion. The former will fry the front and rear glass panels of the iPhone8 and collapse to the quartet; the latter general fire extinguisher is unable to cause fire. It can be said that the battery drum is spontaneous and explosive.

Third, how do you reduce the damage chance? How do we solve it in an interview with a battery explosion?. According to experts, it is not difficult to summarize: For example, if the mobile phone is more than bend, please try not to use it. When the battery is bulky, please replace the battery immediately, if there is condition, the mobile phone is full of electricity or try to Early pull up charge (although there is a protection circuit to be overcharge, the circuit has the probability of failure); Ok, hands are warm.

Privately chatting, expert joking, "When sleeping, put the mobile phone will be safe" (many nights and other safety accidents have occurred at home and abroad). Fourth, the iphone8 drum incident's 话 音 音 音 到 这 这 这 事 事 电 电 电 电 电 电 电 电 电 电 电 电 电 电 电 电 电. Among them, there is a rumor that IPHONE8PLUS uses battery suppliers to Samsung SDI.

If you have any impressions on Note7 explosions last year, it is not difficult to think of the same mobile phone manufacturer at the same time as Samsung SDI. If this news is true, the edge is also worthwhile. Another level is "accident probability", generally, there is a chance of this incident in battery drums, if the phone shipments are low, the big probability drum must be a quality problem.

However, in the shipments of iPhone8plus, the final accident probability is not very high.
