Lithium battery electric car wholesale market experts, lithium battery explosion, the vast majority due to short-circuit caused by the line, the experts explained the specific reasons include charging over-voltage, over-current, aging and so on.

Manufacturing process of lithium batteries, the process is very complex, because in the manufacture of lithium battery technology itself is flawed, easily in the insulation between the poles, leave the metal dust, copper foil, aluminum foil and other related pieces. These materials are easy to do random thermal movement when the battery is hot. If at this time, these fragments close to the positive and negative cells in the middle of the diaphragm, it may cause perforation of the diaphragm, and then lead to micro short circuit. Causing spontaneous combustion or explosion. Due to the lithium battery brand organic electrolyte is flammable, micro short circuit may cause explosion, combustion and other accidents, Guangzhou electric vehicle battery technician explained three main situations:

1. Debris produces sparks, ignites the electrolyte, and then ignites other combustibles;

2, because the lithium battery temperature rise slowly, the shell gradually dissolved, so that corrosive electrolyte leakage.

3, the temperature inside the battery rises, the space inside the lithium battery is very narrow, because the pressure increases and explodes;

Although the lithium battery after years of technological development, but the lithium battery security risks can not be stopped, because the advanced manufacturing process, will inevitably leave debris in the electrolyte. Well, which is good for electric car batteries? For the purchase of lithium battery brands, experts push to build lithium batteries. Because a lithium battery is a regular company, the lithium battery production and sales have strict norms, in addition to the performance of lithium batteries, lithium batteries cheap, in the number and size of the production process of lithium battery quality and debris are controlled in a small range.
