How powerful is the explosion of lithium batteries? Lithium battery blasting: What is the blasting power of lithium batteries? Due to the popularity of lithium batteries, many electric vehicles on the market now use lithium batteries, which also makes lithium batteries explode and fire, causing casualties from time to time. , This is due to some reasons, today the author will come to give everyone a good science. The fire department has already done a crash test of lithium batteries. The lithium battery is taken from an old electric car. In order to prevent excessive energy, the experimenters only used a small lithium battery. The experimenter hit the lithium battery with a hammer weighing 1 kg from a height of 1 meter. The small lithium battery leaked and smoked, and then exploded with a bang, opening a hole in the containment vessel and setting off a fire. And this is only a component of the battery. If the battery is a complete set, the impact of blasting will be very large. Some combustible gases and even some toxic gases, such as hydrogen sulfide and hydrogen fluoride, will appear when lithium batteries are released and out of control, which can cause damage and damage to the human body. The energy of lithium batteries is huge. If used improperly, the consequences are appropriate and dangerous! So, under what circumstances, lithium batteries will have potential safety hazards? The first is overcharging: continuous charging without protection is a big deal Security risks. The second is a short circuit: the internal short circuit may damage the structure to some extent, forming an internal positive and negative direct connection, and the external short circuit may include some conductive wires, copper wires or metal plates, forming an instantaneous large current, which may cause heat and battery burning; The third is heating: For example, if the weather is hot or the ambient temperature is relatively high, the lithium battery inside some organic materials will dissolve and shorten, forming a connection between the positive and negative terminals of the short battery, which will eventually lead to the burning and burning of the battery. blasting.
