Description
Technical Field
The utility model belongs to the technical field of chemical energy storage, and particularly relates to an explosion-proof export system of a chemical energy storage monomer/module.
Background
Thermal runaway of lithium batteries is caused by the fact that the rate of heat generation of the battery is much higher than the rate of heat dissipation, and heat is accumulated in large amounts and not dissipated in time. Thermal runaway of lithium batteries is an energy positive feedback cycle process: the elevated temperature causes the system to heat up, which in turn causes the system to become hotter. There are many causes of thermal runaway of lithium batteries, and there are mainly the following points.
1) Overcharge triggered lithium battery thermal runaway: the battery itself has overshoot protection, but in the event of a problem failure of such overshoot protection, continued charging of the battery can result in battery overshoot triggering thermal runaway. Along with the continuous use of the battery, the aging phenomenon of the battery is serious gradually, the consistency of the battery pack is poorer and worse, and the battery is easy to have thermal safety problem if overcharged. The safe charging should be performed according to the instructions at any time.
2) Overheat triggering lithium battery thermal runaway: in normal use of the lithium battery, when the battery is discharged at a high speed or meets a limit working condition, high-current discharge is required to be continued, at the moment, the temperature inside the battery is gradually increased, and when a large amount of heat of the battery is accumulated, if the discharge current of the battery is not limited in time, the thermal runaway phenomenon of the lithium battery is most likely to be caused.
3) Mechanical triggering lithium battery thermal runaway: the thermal runaway of the battery can be caused by impact deformation of the lithium battery pack, internal short circuit of the battery pack, and other damage to the battery pack.
In addition to the above reasons, overdischarge of the battery, internal short circuits of the battery, and the like may also cause thermal runaway of the battery. Particularly, in the thermal runaway explosion stage of the battery, the electrolyte reacts with oxygen generated by the positive electrode reaction to react vigorously, the battery fires, and the damage such as fire and explosion is caused, so that the life and property safety of people is greatly threatened.
