Battery combustion, explosion, based on site decomposition results involved in the original, personal understanding of the cell: Torthose, burrs, diaphragm discount, etc. Ear-ear interpolation often developed towards the thick cell and within parallel structure, polar ear insulation is not in place, which is easy to cause internal acute short circuits to appear internally acute short-circuit (inner short circuit: This personal is I have a deep understanding, I also scrapped 2K more than the battery. It actually belonging to the unusual nature of design defects: internal acute short circuits), but this situation is almost very small, unless the external force factor.
2, external short circuit: 1AH below the battery out of the burning, the explosion of the explosion is uncommon, usually there is bulging or simply blowing the extreme ear, the personal decomposition is the power lithium-ion battery or large-capacity mobile phone battery. Burning. This involves the use of improper metal outer boxes, and there is no abnormality in the air blowing in the installation site; the power lithium-ion battery is also in common structure fixed measures (considering no circumference), using process battery packs in the user Rocking causes damage to the external insulation protective film of the battery or connecting the line skin, eventually causes short circuit burning.
3, overcharge explosion: This is the most dangerous, but also the company's most afraid, but still occasionally. From understanding, there are two points: A. Users do not use the matching charger as required to destroy the protection line and the user often charge is not limited.
This situation is not fried; B, battery or group Unreasonable and the protective board fails, in this case, a mess is also fried . single battery. 4, the above 3 points are more common, comprehensive: structural design considerations are all the important directions of the combustion or explosion according to the specification, and believe that the current large-end plus manufacturers have been very reasonable.
Measures, personal thinking that a safer material is the king of lithium-electric safety. Second, the battery combustion, explosion, according to the results of on-site decomposition, involves improper use, personal understanding: 1, frequent depth charge and discharge: Lithium-ion battery has almost no memory, many friends are using lithium tram or lithium digital products I like to use the power to be used at a little less (protective board protection) and then charge, and in many people's eyes, this is also a way of activating the battery. In the use of lithium-ion batteries, we use the capacity to charge again.
The situation is called depth charge and discharge. In fact, depth charge and discharge is a major misunderstanding when using lithium-ion batteries. Scientists have drawn through experiments, and the number of depth charge and discharge is constant in the case of other environmental situations and the battery life is proportional.
Discharge can cause battery life to end too early. The lithium-ion battery ended over a long time to use life is very easy to cause battery bulging, which causes an explosion. 2, overcharge and charge and discharge current are too large: this is often happening when the protection board is unreasonable and charging, and we often like to charge the power of the equipment and make your own equipment.
The anti-time is longer, but many people don't understand that long-term overcharge and overplay will have serious damage and damage to lithium-ion battery performance, which will cause extreme conditions such as explosions, so battery electricity Okay, it's all, I have been inserted on the charger, sooner or later, it will make a tragedy. At the same time, we also need to charge the current and the general current load of the electrical appliance when charge and discharge. Excessive current load is extremely easy to cause internal short circuits in the battery, thereby destroying lithium ions, triggering circuit safety hazards, sympathy, related charging The type of charger voltage, the truth is also the same.
So we have to pay attention to the charger when you use the charger. However, after many accidents have been experienced, the manufacturers have finally have actions, and have added dual protection or multiple protection for most manufacturers, especially electronic digital products, and try to turn this situation. What happened, however, the enhancements of users themselves are still very important.
The temperature of the lithium-ion battery is extremely sensitive. If it is used for a long time, it may cause great impact and harm to battery life.
