Is the gas toxic once the battery burns?

The gases produced by the combustion of batteries are toxic.

Reason:

1. A chemical battery refers to a device that can convert chemical energy into electrical energy. The main part includes an electrolyte solution and two positive and negative electrodes immersed in the solution. When used, a wire is connected to two electrodes and current passes through it (discharge), thus obtaining electrical energy. After being discharged to a certain extent, the electrical energy becomes weaker. Some can be recharged and reused, called batteries, such as lead-acid batteries, iron-nickel batteries, etc. Some cannot be recharged and are called primary batteries, like primary batteries. such as dry cells and tanner batteries, fuel cells, etc.

2. Some batteries contain Hg [mercury]. When this substance reacts with oxygen at high temperatureture, it generates Hgo [mercury vapor], toxic to the human body. It should be noted that ingestion of trace amounts of liquid mercury does not usually cause serious poisoning reactions, but mercury vapors and mercury salts (except for some extremely soluble mercury sulfides) are highly toxic. and can cause serious poisoning after oral administration, inhalation or contact. Brain and liver damage.

Precautions when purchasing batteries:

1. When purchasing batteries, battery-based products. with "Inspection Exemption", "Chinese Famous Brand" signs and local famous brand battery products, the quality of these products is guaranteed.

2. According to the requirements of the electrical appliance, select the type and sizeapplicable battery packs, and purchase the suitable battery for the electrical appliance according to the size and power consumption characteristics of the electrical appliance.

3. Pay attention to the production date and shelf life of the battery, and purchase batteries (new batteries have good performance).

4. Pay attention to the appearance of the battery. You should choose a battery with exquisite packaging, neat and clean appearance and no signs of leakage.

5. Pay attention to the battery logo. The battery brand should indicate the manufacturer name, battery polarity, battery model, rated voltage, brand, etc. ; buy batteries without Chinese factory name or production name). Products without date or shelf life or without expiration date or application standards. When purchasing alkaline zinc-manganese batteries, you should check whether the model carries the mots ALKALINE or LR

6. Because the mercury in the battery is harmful to the environment, in order to protect the environment, you should choose batteries with the words "mercury-free", "0% mercury" and "no added mercury". " on the brand when purchasing.

How to deal with the gas released when disassembling a lithium battery Treatment

If some of the gas produced by the combustion of the lithium battery lithium from the cell phone was inhaled, you need to drink more water and stay in a well-ventilated place for a few minutes., I used to take the battery apart a lot, and it burned a lot. I often watched it burn, and sometimes I used sand to put it out

You only inhaled a little, so don't make a fuss

Why a lithium battery.does it burn after being pierced by a knife?

The gas inside must be the gas produced by the decomposition of the electrolyte during the battery cycle, mainly CO2. , because the electrolyte The main ingredient is organic carbonate. These esters are fragrant. Just open the window and let the smell in. To dispose of it, keep it away from fire sources and place it in a dark warehouse. There are companies that specialize in recycling this stuff. Just call them to recycle them.

For lithium polymer batteries, it is easy to short circuit the positive and negative electrodes after being scratched by a knife. A large amount of heat will be released in a short time, causing freezing and. the positive electrode materials decompose and release gas which causes an explosion ~

This is much more dangerous for lithium-ion batteries. In addition tos problems above, the components of battery electrolyte include propylene carbonate, ethylene carbonate and. dimethyl carbonate, all of which are extremely flammable. Lithium hexafluorophosphate Not only will it burn, but it will also decompose and release phosphorus fluoride when heated, exacerbating the effect of the explosion. At the same time, the battery separator is generally made of PP or PE, which are flammable~

And if the design of the positive and negative electrodes of the battery does not match, or the capacity of the battery negative electrode to absorb lithium ions is weakened after the battery has been cycled several times, the positive electrode. The lithium ions extracted from the battery cannot be fully integrated into the negative electrode, resulting in the battery containing lithium element after explosion, it will burn when exposed. in air and react with water ins air~

The above explosions are all based on the failure of the explosion-proof design of the battery under the premise~
