If the lithium battery leaks, it will definitely not be good if you touch the lithium battery again. The electrolyte is lithium hexafluorophosphate, which will form hydrofluoric acid when it encounters moisture in the air. It's harmful to people.
If there is no leak, do not hesitate to touch the outer packaging of the battery core, provided that the outer packaging is not damaged.
I often touch battery cells and find useless ones.
The consequences of spontaneous combustion of electric vehicles are very serious due to flammable and explosive gases, highly toxic fumes and the failure of firefighters.
Nowadays, mobile phone batteries are mainly rechargeable lithium-ion batteries (hereinafter referred to as lithium batteries or lithium batteries).
The battery water inside this lithium battery is actually lbattery electrolyte. The electrolyte is located inside the cell phone battery cell and undergoes an electrochemical reaction with the battery's electrodes to store electrical energy.
The electrolyte is a mixture of the following substances:
Ethylene carbonate, propylene carbonate, diethyl carbonate, dimethyl carbonate, methyl ethyl carbonate, hexafluorophosphate lithium, pentane Phosphorus fluoride, hydrofluoric acid? and a small amount of additives.
Several of these substances have some toxicity:
Diethyl carbonate
After inhalation, it can cause headaches, dizziness, weakness, nausea, difficulty breathing, etc. Ingestion may irritate the gastrointestinal tract. May cause skin irritation with prolonged and repeated contact.
Phosphorus pentafluoride
It is very irritating to the skin, eyes and mucous membranes.uses. If inhaled in large quantities, it can cause respiratory inflammation and pulmonary edema.
Hydrofluoric acid
It is toxic and corrosive. Inhalation of vapors or contact with skin may form ulcers that are difficult to heal.
According to the decomposition and analysis of electrolyte components of mobile phone lithium battery, the electrolyte has certain toxicity. Although the amount of electrolyte in the battery is not large, it will still have adverse effects on the body when people inhale it through the respiratory tract, which you call "smelling it with the nose".
In addition, after significant leakage of battery electrolyte, the battery capacity will also decrease significantly.
If the power of the mobile phone often leaks, it is still recommended to replace the battery or ask the after-sales service to replace the battery.erie (all-in-one machine with built-in battery).

?Which topic has been the most popular in the past two years
The electric vehicle spontaneous combustion incident actually certainly part
Although there is no traffic celebrity endorsement
But every time a spontaneous combustion fire occurs
The moments and hot search lists will be refreshed
Spontaneous combustion does notis not a "patent" for electric vehicles
Fuel-powered vehicles can also ignite and catch fire spontaneously.
But why are electric vehicles so popular?
In addition to great attention, TA is more harmful
The vast majority of spontaneous combustion of electric vehicles is caused by "thermal runaway" of lithium batteries
p>
TA will result in the following three hazardous situations
Lithium battery explosion
Lithium batteries are active and flammable by nature
< p>When a lithium battery undergoes thermal runawayA violent reaction occurs inside the battery
Oxygen and d Huge amounts of heat are released
Due to the limited space in the battery pack
p>This heat will build up in a short period of time
< p>If the heat and gas are not released in timeThe batteryerie can explode
Although the battery The explosion power is not as good as that of explosives
But TA will be accompanied by splashing of copper foil, electrolyte and other substances
These substances with a maximum temperature of almost 1000°C
not only causes burns, it corrodes the skin and can also form new spots inflammation
"Immune" to common fire extinguishers
To be honest, fighting electric vehicle fires
is still a global problem.
We know that the common principles of fire extinguishers are:
Spray carbon. dioxide and dry powder to isolate the oxygen
Let the burning material "suffocate" to put out the fire
But this is different from the spontaneous combustion of vehicles at fuel
The spontaneous combustion of lithium batteries not only reacts more quickly
butalso generates oxygen by itself
Ordinary fire extinguishers are therefore not immune to it Function
How to put out a battery fire lithium is to cool it
So, when an electric vehicle spontaneously ignites at present
the firefighters' solution is to rinse it with plenty of water< /p>
Remove a large amount of heat and cool it completely
The escaping gas is highly toxic
The main component of the electrolyte of acid batteries lithium is
Lithium hexafluorophosphate (LiPF6)
This substance itself is harmful to the human body
What is even more terrifying is that during the combustion process
LiPF6 will also generate many toxic substances
For example: HF, CO, HCN, etc.
Hydrofluoric acid ( HF) will corrode bones
If not cleaned in time, amputation may occur
Toxic gases suchthat HCN spreads very quickly
Once they enter the human body
It can range from poisoning to death
What to do if you notice that an electric vehicle spontaneously combusts?
The stages of spontaneous combustion of lithium batteries are divided into:
"Temperature rise-bulge-breakdown-smoke-fire"
Generally, we generate lithium batteries. through the smokeThere is an abnormality in the electric car
There is not much time to escape at this time
So remember not to try to put out the fire
The most correct thing to do is to run as far as possible< /p>
