How to deal with a swollen battery

A swollen battery must generally be recycled by a professional to avoid causing pollution. If there is no way to dispose of it, throw it into the classified recycling bin at the telecommunications service provider's service point. Additionally, the battery bulge may explode, so you should stop using it. Lithium batteries swell due to overcharging during charging. The internal chemical properties of the battery change and gas is produced. Typically, soft polymer batteries “swell” when overcharged. If they are steel shell batteries, they explode.

An overcharge will cause all of the lithium atoms from the positive electrode material to flow into the negative electrode material, causing the initially full grid of the lithium atom to deform and collapse. positive electrode. This is also one of the main reasons for the declinein. in the power of the lithium battery. During this process, there are more and more lithium ions in the negative electrode. Excessive buildup causes lithium atoms to turn into strain crystals, causing the battery to swell.

How to remove battery bulge

The Pacific Automotive Network lithium iron phosphate battery is bulged and cannot be used. During the inflation process, the capacity of the lithium battery decreased and the standby time became significantly shorter. In severe cases, the standby time will be extremely short, you may not even be able to make calls, and it will restart as soon as you make a call. At this time, the battery usually needs to be replaced.

Will the lithium iron phosphate battery bulge explode?

The bulging lithium iron phosphate battery may explode, so be sure to stopto use it. Lithium batteries swell due to overcharging during charging. The internal chemical properties of the battery change and gas is produced. Typically, soft polymer batteries “swell” when overcharged. If they are steel shell batteries, they explode. Be careful when using it. It is best not to use cheap chargers. Cheap chargers have a big impact on battery life. It is best not to use a “bulged” battery as it is very dangerous and it is recommended to replace it.

The main reason why lithium iron phosphate batteries swell is that a violent reaction similar to a short circuit occurs inside the battery, generating a large amount of heat, which which causes the electrolyte to decompose and gasify, and the lithium battery will swell. When a problemIf swelling occurs in a lithium iron phosphate battery, it is best not to continue using the problem battery. Because the battery core expands, when the expansion reaches a certain limit, it may explode, which is very dangerous. For your own safety, it is best to replace the lithium battery as soon as possible when you notice a bulge.

Is a bulging lithium battery dangerous?

I think everyone may have seen or heard about battery swelling, and there are even new incidents of explosions and casualties caused by lithium polymer battery swelling. A bulging battery will affect its use and cannot fit into a cell phone or digital camera. Additionally, the presence of gas between the battery plates will also affect the charge and discharge capacity of the battery. Lithium batteries have specific requirementses strict when it comes to chargers and cannot be connected. At will power supply. As for careless charging, you should use a charger specifically designed for lithium batteries. If the charger used does not meet the requirements, it may cause battery swelling, safety accident or even explosion.

Lithium iron phosphate batteries will not explode or catch fire under normal circumstances. Lithium iron phosphate batteries are safer when used normally, but nothing is absolute. Danger can still arise in some extreme situations. This has a lot to do with each company's material selection, ratio, process and subsequent use.

Although lithium iron phosphate material has the highest thermal stability and structural stability among all current cathode materials in terms of thermodynamics, and it has also been verified in actual safety performance tests, there are still many problems in terms of materials and structural stability. In terms of the possibility and probability of a short circuit inside the battery, this can be the most dangerous.

Causes of lithium iron phosphate battery swelling

1. Swelling of lithium iron phosphate batteries caused by overcharging will cause all the lithium atoms in the positive electrode material to sink. Material of the negative electrode, resulting in the deformation and collapse of the original complete grid of the positive electrode, which is also one of the main reasons for the power decline of lithium iron phosphate batteries . During this process, there are more and more lithium ions in the negative electrode. Excess accumulation causes lithium atoms to turn into strain crystals, pcausing swelling of the lithium iron phosphate battery.

2. Bulge caused by over-discharge During the first charging and discharging process of the liquid lithium-ion battery, the electrode material and electrolyte react at the solid-liquid interface to form a passivation coating layer . the surface of the electrode material.

The method to restore the battery bulge is to use your fingers to find First pierce the gap in the battery, just poke a small hole with a needle and let the air inside escape.

Overcharging will cause all of the lithium atoms in the positive electrode material to collide with the negative electrode material, causing the grid to initially deform and collapse full of the positive electrode. reason fore the drop in power of the lithium battery. During this process, there are more and more lithium ions in the negative electrode. Excessive buildup causes lithium atoms to turn into strain crystals, causing the battery to swell.

A bulging lithium battery may explode, so be sure to stop using it. Lithium batteries swell due to overcharging during charging. The internal chemical properties of the battery change and gas is produced. Typically, soft polymer batteries “swell” when overcharged. If they are steel shell batteries, they explode. It is best not to use a “bulged” battery as it is very dangerous and it is recommended to replace it.

Battery function:

Battery refers to a cup, tank or other container or part of a composite container that contains a batteryelectrolytic lution and metal electrodes to generate electricity. fluent. Device that converts chemical energy into electrical energy. It has positive and negative poles. With the advancement of technology, batteries generally refer to small devices capable of producing electricity. Like solar cells. Battery performance parameters mainly include electromotive force, capacity, specific energy and resistance.

Using the battery as a power source can achieve stable voltage, stable current, stable power supply for a long time and little influence from the outside world. In addition, the battery structure is simple, easy to carry. and charging and discharging operations are simple and easy. It is not affected by external climate and temperature, has stable and reliable performance, and plays a great role in every aspects of modern social life.
