We first analyze why lithium battery will explode or combustion from electrical. Burning or explosion, usually because of the heat collecting, not spread, accumulate to the fire point, or the heat is concentrated in a certain space to a certain extent, will happen. As a battery, it is attempted, and the above situation is usually not out of the following four reasons.
1, internal short circuit (mostly soft bag large monomer): structural or process defect leads to extreme ear interposers, diaphragm wrapping is too small, burrs, diaphragm discount, etc. Ear-ear interpolation tends to appear in a thick battery and within parallel structures, the extreme ear is insulated, in the subsequent finished product plus protector or the use process is easy to cause internal acute short circuits to have a combustion or explosion (internal short circuit: this person is I have a deep understanding, I also scrapped 2K more than the kind of battery, actually belonging to the abnormal nature of the design defect: internal acute short circuit), but now this situation is almost very small, unless the external force factor. 2, external short circuit: 1AH below the battery out of the battery, the explosion caused by the burning, usually a bulging or simply blows the extreme ear, personal analysis is the power lithium-ion battery or massive mobile phone battery outline leads Burning.
This involves the use of improper metal outer boxes, and there is an abnormality of the battery smoke in the installation site; the power lithium-ion battery is also common in a common structure fixed measures (considering no circumference), in the user uses the process of battery pack Rocking causes damage to the external insulation protective film outside the battery or connecting line skin, which ultimately leads to 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 gauge Unreasonable and the protective board fails, in this case, a mess is also fried . Single-section battery is similar.
4, the material itself is not limited. The material is not limited, it may have an overheating under the calibrated voltage current, thereby accident. .
