In the media these past few days, the burning samsung note7 bombing may have been seen by all. The official analysis shows thatLithium batteriesReason。
Each of us uses lithium batteries. Can you learn from it, and let me tell you how lithium batteries work。
Nowe7, which was listed before applephone 7, was its counterweight to apples, while previous market feedback showed that the flagship mobile phone was popular with consumers and had the promise of putting samsung in a favourable position in the competition。
But just before iphone7 was about to be released, there was an explosion in note7。
According to the chairman of the samsung mobile department, gaudong town, at a press conference, the probability of a deficiency in the note 7 battery was only 24 ppm, but in order to ensure the safety of the user, samsung decided to recall all of the note 7 sold。
Look at the data: 24 ppm of battery defects
Here's how lithium batteries are charged:
The arctic materials of lithium ion cells usually consist of lithium active compounds, the negative poles being the carbon of the special molecular structure. The main components of the common arctic materials are licoo2 when charged, added to the battery's two poles, forcing the positive compounds to release lithium ion, embedded in the carbon of the negative polar molecule in the tablet structure. ... When discharged, the lithium ion is removed from the carbon of the layer structure, reconnecting with the positive compounds. The movement of lithium ion produces currents
Lithium ion cell operation - structure
Lithium ion batteries are a substitute for the metallic lithium batteries that have appeared in previous years and consist mainly of positive and negative poles, electrolytics, diaphragms and casings。
Positive - using carbon poles that contain lithium ion, lithium becomes lithium ion when discharged, detached from the cell anode, reaching the lithium ion cell cathode。
Negative poles - materials are selected to sequester lithium compounds as close as possible to lithium levels, such as carbon materials including natural graphite, synthetic graphite, carbon fibre, metallic carbide, etc。
Electrolyte - a mixed solvent system with alkyl carbonate, such as ethylene carbate, acrylate and low viscosity diethylene carbonate。
Diaphragm - the application of polyolefin micro-porefilms such as pe, pp or their composite membranes, in particular the three layers of the pp/pe/pp diaphragm, not only has a low melting point, but also has a high perforation resistance, providing thermal insurance。
The outer shell - using steel or aluminium materials, the cap component has blastproof power。
Misunderstanding1: non-original chargers destroy batteries
Truth: non-preliminary chargers, although not ideal, do not have problems. You need to avoid using the bunker。
Cheap storage chargers should never be bought, and if the chargers are too expensive, those brand chargers that are not very expensive can be selected. The site, liveback, has done a detailed experiment to compare the original chargers, brand chargers and warehouse chargers。
The results show that, while brand chargers do not work as well as they do in their originals, they do work well. But it's barely working。
Misunderstanding 2: refilling with electricity
The truth: it makes more sense to charge mobile phones every day than to charge them in depth from time to time。
Lithium ion batteries perform better after charge, and always use mobile phones to turn off the charger to cause damage to the battery. Cellular batteries have a limited recharge cycle, which is a cycle when each battery is completely out。
Misunderstanding 3: never have to turn off
Truth: your phone may be just a machine, but it still needs rest. According to an apple genius, in order to maximize the continuation of the voyage, you should shut down your phone from time to time, especially at night while sleeping。
Apple experts also suggested that users would need to turn off at least once a week to keep the voyage going。
The shutdown is equally important for the android device, and a simple restart can help with the response。
In conclusion, there is nothing wrong with the normal use of our phones。
