Rechargeable batteries are a source of fire
No matter how hard you try to reduce it, if you live, a certain amount of garbage will always come out.
Therefore, it can be said that the garbage collection system is one of the important infrastructures that support our daily lives.
If you don’t handle it properly, it’s going to be hard.
Garbage overflows, making it difficult to maintain a hygienic living environment.
In recent years, it seems that at the site of the important garbage collection, “fires” have occurred frequently, and it seems that they have been in trouble.
In a collection truck or treatment facility, a fire suddenly ignites, sometimes causing a large fire that takes half a day to extinguish.
There is also a risk of injury to workers, which is a problem that cannot be overlooked.
For example, according to data from the Tokyo Fire Department last year, “rechargeable batteries” had the largest number of cases with 24 cases, followed by “aerosol cans” with 10 cases, “lighters” with 4 cases, and “cigarette butts” with 1 case.
It is said that more than 50 fires occurred, including those whose cause cannot be identified.
The rule that spray cans must be completely degassed and then separated from other garbage has been well known for quite some time.
If cans with remaining gas are mixed with ordinary “non-combustible garbage” or “burnable garbage”, they are dangerous because they will explode without being noticed by being hung on the crusher of a collection truck or treatment facility.
Recently, fires caused by lithium-ion batteries have been increasing.
Even in the aforementioned data, it is listed as the number one by far. Lithium-ion batteries are rechargeable batteries widely used in mobile phones, notebook computers, mobile batteries, etc., but they often catch fire when crushed by a crusher.
If you try to explain the mechanism of the battery in detail, it is a little difficult with the author’s knowledge, so I will keep it simple, but the point is that there is a positive electrode and a negative electrode, and the energy generated by the transfer of electrons from negative to positive is electricity, and in the case of disposable dry batteries, it is over when the electrons have moved, but the rechargeable battery returns the electrons to the negative electrode, Since it can be returned to a state close to the original, it can be used repeatedly.
It is an indispensable and grateful tool in today’s mobile society.
If normal, the electricity generated in the battery flows from the positive electrode to the negative electrode through substances with large electrical resistance, such as home appliances.
The positive and negative poles are not originally directly connected (they are made to be).
However, when a strong impact is applied from the outside, the impetus (?) It seems that the two poles are sometimes directly connected.
Well, it’s not that strange because the poles are in the same container. This is called a short circuit.
When a short circuit occurs, a tremendously large current flows.
Does it mean that since there is no resistance from home appliances in between, too much energetic energy with almost no attenuation will rush around, burning the surroundings and igniting?
Rechargeable batteries seem to be more likely to experience this short circuit, and it seems that there are many cases where rechargeable batteries mixed in with other garbage are inadvertently thrown into the crusher and catch fire.
This is our responsibility to dispose of garbage.
Batteries should be properly separated and never mixed with other garbage.
By the way, disposable dry batteries can also catch fire in a short circuit.
It seems that this is likely to happen with button batteries. It seems that if you accidentally store the plus and minus electrodes together, the metal outside the battery becomes a conductor and a short circuit occurs.
Wrap the battery with vinyl tape and insulate it before storing.
