Does it feel like the battery will explode if it swells, and will the electric vehicle battery explo

First of all, it is recommended that you do not use this battery, even if it does not explode! The battery cell of the mobile phone battery is sealed, and the condition for it is that there is a large amount of gas, and the shell can not be installed, it will burst, just like a balloon, when the gas is too much to be installed, it will burst, if there is not much gas, it will drum, the battery to produce gas usually occurs when the short circuit and overcharge, when the current reaches a few amps, the battery will heat up, and the gas will be produced in the cell, and when the gas reaches a certain level, the material in the battery cell will spontaneously combust when it meets the air, so there will be **burns, Now for safety reasons, a good cell makes an explosion-proof valve, the valve is very small, the purpose is when the gas has not yet exploded, but when the explosion is about to burst, the valve is broken, release the gas, and make the battery.

If the battery swells, then the battery will not be easy to use, it will be difficult to charge, and the power consumption will be relatively fast after charging, and it will soon run out of power when installed in the mobile phone.

In order to ensure the stability of the test, the high-current shrapnel microneedle module can play a stable connection and conduction, and when transmitting current, it can carry a large current of 1-50A, and the overcurrent is stable without attenuation.

The expansion of the electric vehicle battery will not **, but it will cause spontaneous combustion.

Relevant experts pointed out that the battery thermal runaway of electric vehicles should be the main cause of most electric vehicle accidents. Collision, water immersion, and aging may cause a short circuit and cause thermal runaway of the battery.

The main causes of battery thermal runaway include uneven temperature of the battery pack itself, high temperature in local areas, overcharge and overdischarge, external short circuit, internal short circuit, etc., as well as mechanical reasons, such as water ingress, poor sealing, collision, etc. In addition, the battery is also prone to thermal runaway when charging, because the battery is connected to the charging system during charging.

Lithium-ion batteries for electric vehicles are becoming the mainstream of electric vehicle batteries. Industry insiders believe that with the continuous improvement of safety monitoring, thermal control technology and battery safety verification level, the safety of lithium-ion batteries will continue to improve.

Ouyang Minggao, academician of the Chinese Academy of Sciences and executive vice chairman of the China Electric Vehicle 100 Association, said at the China Electric Vehicle 100 Forum in early 2019 that it is unrealistic for lithium-ion batteries to completely eliminate thermal runaway from the single level.

The thermomechanical design and control design of the battery system can be considered to prevent the induction and spread of thermal runaway, and no accidents will occur even if the thermal runaway occurs in the unit. Starting from improving the safety of the battery itself, it is necessary to develop a new type of solid-state battery.

If the electric car uses a lithium battery, it will expand if it is charged and heated, mainly because the temperature overheating protection is well controlled early, and Tesla cars are cooled with water and air conditioning.

Correct, it is best to change the battery expansion to a new one, as long as it is not too large, it can generally be used for three or four months to about half a year, and it is safe.

First, money second, the battery must be used for a long time must be supplemented with distilled water to dissipate heat from the battery.

The expansion of the electric vehicle battery is caused by the expansion of the active material of the battery or the charging current is too large, and the probability of the battery is too low.

There is such a possibility, the battery is swollen, don't use it, and quickly replace it with a new one.

Electric vehicle batteries generally do not, because after the internal pressure of the battery is high, there is a pressure relief cover on the battery, which will release the high voltage inside the battery.

Generally not, but there are exceptions to everything, lead-acid batteries are still very safe, but in such a situation, the battery needs to be replaced in time, and the charger is tested to see if it is normal

Don't use it again if the battery is swollen, this situation is very dangerous, and it won't**.

Generally not... The battery is swollen because it has been charged too many times... Causing some chemical reaction in the battery solution inside.

It's not that easy.

At most, it won't be needed for a certain time.

If it is not instantaneous expansion, it will not be **, at best it is just leakage, the reason for the expansion is mainly overcharging or the decomposition of the electrolyte formed leads to the internal volume becoming larger, (lithium hexafluorophosphate decomposes to lithium fluoride and light fluoric acid), or the moisture control in the process of making is not in place, resulting in the reaction of moisture and electrolyte into strong acid hydrogen fluoride gas when the battery is charged, and the internal volume becomes larger so that the battery expands, commonly known as drumming. It won't damage the phone, but the battery resistance is high, and it is used quickly, and your battery has been used for three years, that is to say: it is charged once every three days, at least 500 cycles, which is quite good for the mobile phone battery.

Brand batteries generally do not **, because of the safety valve inside the battery. For example, the gas will run out of the safety valve, but the battery will be useless. For example, if the inferior battery is damaged inside, a large amount of gas is produced inside, and some safety valves are not done well, then it is possible that the gas cannot be released.

Happen**.

This will not appear in the phenomenon of ** under normal circumstances. It may be caused by playing games while charging and causing excessive temperature at high temperatures. So you can use the phone with confidence, but you need to pay attention to it.

It is recommended not to use it, it is recommended to replace it with a new battery, such as using an authentic original mobile phone battery, or using a commercial battery of a well-known brand such as a domestic Hony battery with guaranteed quality.

This is very common. 1. You often use the universal charge to recharge. This seriously injures the battery.

2. You are using self-packed batteries in the mall, those are time bombs, and 90% of the batteries are such batteries. Ten percent of them are miscellaneous batteries. 3. You will indeed be in this situation.

Battery swelling generally doesn't**. Battery expansion is caused by irreversible chemical reaction inside the battery to produce gas, usually a long-term process, if the battery has expanded, it means that the battery aging has been very serious, the capacity will be very low, basically can not continue to use, and the obvious expansion will also cause equipment such as mobile phone shell to crack or can not be loaded, so timely replacement or discarding.

The battery is generally due to the violent reaction caused by internal short circuit, high temperature and other factors, that is, the chemical materials inside the battery burn, or the battery may expand in the early stage of combustion, but the long-term slow expansion generally does not lead to.

The metal properties of lithium are destined to undergo oxidation reaction when the bulge leaks into contact with oxygen in the air, and it will oxidize and produce **. The lithium battery bulge indicates that his positive and negative plates are deformed, and the battery capacity will also drop sharply at this time, and continued use will also lead to risks such as battery ****, so it is recommended that you replace the battery. Hope it helps, thank you.

After the mobile phone battery is swollen, if you continue to use it, if you do not cut off the power supply in time for too long after charging, you may experience burning, ** and other phenomena.

For the "activation" of lithium batteries, many sayings are: the charging time must exceed 12 hours, and the full charge and discharge must be done three times repeatedly in order to activate the battery. This statement that "the first three charges should be charged for more than 12 hours" is for the rechargeable battery in the 90s of the last century, when the nickel-cadmium battery had a memory effect and needed to be fully charged to ensure the battery capacity.

The mobile phone uses a lithium-ion battery, it has no memory effect, it can be fully charged in 2-3 hours, and a full charge is enough. If the first three charges and discharges of a new battery can really reach 12 hours or more, it will cause great damage to the battery, which may cause the battery to swell and even burn.

Fortunately, both the phone and the charger have protection circuits, and when charged to 100%, the power will be automatically cut off, and it will not continue to charge when plugged into the charger. However, it is better to unplug the charger at this time, in case there is a problem with the charger protection circuit and the battery is overcharged, causing serious damage to the battery material and affecting the capacity and life of the battery.
