Samsung Galaxy Note 7 is made so that on exploding smartphones began to rise quite often. And, in particular, explosion of the batteries, because they are responsible for this type of fault.
Remember one thing, there is no such thing as a completely secure the battery. Links can pass the necessary quality tests, can work in almost all devices available on the market, but it’s not what it shows. Lithium-ion battery is actually a little chemical bomb. It is a gentle components that can just stop working properly. And it may be tragic and end with burns, serious injury or death to nearby people. However, this does not mean that the equipment manufacturers do not have this effect. What it is not.
Why do batteries sometimes explode?
the Vast majority of exploding batteries comes with small companies that have not accepted the decision of the brand, so they try to compete on the field technical specifications. Unfortunately, currently used lithium-ion batteries is not so easy. This technology improved to the limit and their progress and even on the Pacer then is very difficult.
I Think that the safety of the user is regarded as a limited liability company. Some small companies decide to increase the maximum charge level of their batteries to a dangerous level. Because although not everyone knows about it, the battery not use their full capacity, because of security reasons. In order to avoid overload.
in addition, poor quality batteries often do not apply some multi-layered security system that should protect the device from damage. If a few of them not working, or the battery will fail grossly, the link can become extremely hot, napuchnąć and burst. Through the thus formed hole will gush hot and acrid fluid, which under the influence of contact with air illuminates and the battery begins to produce a large quantity of acrid smoke. In short, will be that could see unhappy owners of Samsung Galaxy Note 7.
Why is battery in Galaxy note’d 7 Ah blew up?
Well, however, such a large company like Samsung rather used all the necessary protection. What, then, was the cause of the explosions of smartphones Galaxy Note 7? To better explain, you should learn how it really works battery. The battery has two electrodes, electric conductors, located on both sides of the battery. One of them collects positively charged ions and is called the cathode. The cathode is filled with oxide of lithium and other metals, and it saves electricity. The second electrode, the anode, collects negative charges. When the battery is charged, lithium ions move from the cathode to the anode. When the battery is used, the movement of ions occurs in the opposite direction.
Between the cathode and the anode is the electrolyte. It is a chemical substance that helps the ions to move. However, despite the fact that the ions are traveling between the cathode and the anode, these two components must be separated from each other, in the end, each is completely different, almost opposite, and the second element can this process be broken. To separate from each other of the anode and cathode, manufacturers of batteries using separators. The problem also could be shorting between individual cells (which also must be separated by a separator), roughly made battery.
Graphics attached to the above tweet suggests that the construction of batteries manufactured by Samsung SDI differed from those created by Chinese ALT. According to this theory the implementation could affect smaller distances between the sensor elements.
Samsung and independent analysts some time ago confirmed that these two reasons led to the failure of the smartphone Galaxy Note 7. Accident that concerns only 0.1 percent. available on the market copies, but led to the closure of production and withdrawal from the market of the (excellent, by the way) and wpędziła smartphone of the Korean company in huge trouble.
From our investigation, it appears that the problem was sensor battery. Overheating of the battery occurred when stykała anode to the cathode. This is the result of rarely occurring errors in the production of batteries – said Samsung during the panel Q&A.
Loss from Samsung as a result of such omissions is currently estimated at more than $ 17 billion, and a powerful loss wizerunkowe, which it is impossible to count the money.
NOTE: Samsung launched the Galaxy Note 7 with production and sales. All owners of this device, please return as its further use may be dangerous – risk of explosion or fire. Customers who bought Samsung Galaxy Note 7, can replace it with the Galaxy S7 Edge, or to request a refund. More information on this topic you’ll find here and here.
