Your mobile phone’s battery is a crucial part of your device, as it provides you with the necessary power to operate it. The battery is made up of a lithium-ion cell, which utilizes a chemical reaction to produce electric power. This chemical reaction occurs within the battery’s electrodes, which are made up of a cathode and an anode, and an electrolyte solution.
As you use your phone, the battery’s electrodes start to degrade, and the chemical reaction that produces power becomes less efficient. This degradation is a natural process that occurs over time and is influenced by various factors, including usage patterns, temperature, and charging habits. Moreover, if the battery is exposed to extreme temperatures or experiences a physical impact, the chemical reaction can be disrupted, leading to swelling.
What will happen if your lipo battery swell?
When a battery swells, it creates gas, which causes the battery to expand and can potentially damage the device. In some cases, a swollen battery can even become a safety hazard. Therefore, it is important to take proper care of your battery and ensure that it is not exposed to extreme conditions or subjected to physical abuse. By taking care of your battery, you can ensure that your device operates smoothly and safely for a longer period of time.
When the battery starts making gas, this process is known as out-gassing, which makes your battery start swelling. If you keep putting your phone on charge and using it, the battery will keep getting swelled to a point when it will finally burst.
So why lipo battery will swell?
Lipo batteries swell due to a buildup of gas inside the battery caused by the decomposition of electrolytes. This can occur if the battery is overcharged, over-discharged, or if it is exposed to high temperatures. The swelling is a sign of a damaged or faulty battery and can lead to a risk of fire or explosion if the battery is not replaced. Today we are going to clearly explain two reasons:
Aging
Every electronic device comes with an expiry date and batteries too. It is important to note that batteries age over time, and if you have been using the same lithium-ion battery in your cellphone for years, it is likely that its capacity has decreased and that it has started to exhibit signs of wear. This could be why the battery has started swelling, as older batteries are more prone to this issue. It is important to keep in mind that the lifespan of a battery can be influenced by a number of factors, including usage patterns, temperature, and charging habits. Therefore, it is recommended to monitor your battery’s health and replace it if necessary to ensure that your device continues to function properly.
Overcharging
We have already talked about the phenomenon of out-gassing in batteries. This typically occurs when a battery is overcharged, although age can also be a contributing factor. When you leave your cellphone plugged in for an extended period of time, the electrodes and electrolytes within the battery begin to generate heat and gas once the battery is fully charged. Therefore, it is important to monitor your phone while it is charging.
If you consistently leave your phone plugged in for long periods of time, the gas generated by the battery may eventually cause cracks to form, potentially leading to an explosion or other serious safety issues.
To avoid this, it is recommended that you unplug your phone once it is fully charged, and avoid leaving it plugged in for extended periods of time.
Will it be safe to use a swollen phone battery?
If your cellphone battery is swelling or getting swelled, that means the battery is producing gas and causing out-gassing. This situation doesn’t sound ideal, and you shouldn’t use that swollen phone battery. If you keep using and charging it, there will be significant consequences.
Swelling of the battery is a sign of an underlying issue that requires immediate attention. The production of gas inside the battery is a result of an abnormality in the chemical reaction that powers the battery. Continual use of a swollen battery has the potential to cause further damage to the battery, as well as to the device it powers. In some cases, the battery may even explode, causing damage to the surrounding environment and putting the user at risk.
It is important to take immediate action when you notice a swelling battery, such as discontinuing use of the device and seeking professional assistance. This may involve replacing the battery or the entire device itself, depending on the severity of the issue. By taking the necessary steps to address the problem, you can avoid the significant consequences that may result from continued use of a swollen battery.
Signs of a Swollen Lipo Battery
It is important to pay close attention to your cellphone’s battery to ensure it is functioning properly. One sign that your battery may be swelling is a noticeable change in its size and shape. This could be an indication of a chemical reaction taking place within the battery, which could lead to serious consequences if not addressed promptly. In addition to physical changes, other signs that your battery may be swelling include decreased battery life, slow charging times, and overheating. It is vital to be aware of these signs and take action immediately to prevent any potential damage to your device or harm to yourself:
Bulging battery
If your phone’s battery is swollen, it will appear visibly larger than it should be. The battery may bulge out of the phone’s casing or appear to be misshapen.
Difficulty in removing the battery
If you find it difficult to remove the battery from your phone, it may be due to the swelling of the battery.
Overheating
A swollen battery can cause your phone to overheat. This can lead to the phone shutting down or becoming unresponsive.
Battery life
A swollen battery may cause your phone’s battery life to decrease significantly. You may find that your phone’s battery drains faster than usual.
Physical damage
If your phone has physical damage, such as cracks or dents, it may be more prone to a swollen battery.
If you notice any of these signs, it’s important to stop using your phone immediately and seek professional help. A swollen battery can be dangerous and can cause harm to you and your device.
Understanding why LiPo batteries swell is crucial for anyone using or working with these powerful energy storage devices. LiPo battery swelling occurs due to a variety of factors, primarily related to internal chemical reactions and improper handling. By examining these reasons, we can take proactive measures to prevent battery swelling and ensure our safety.
How to Prevent Li-Po Battery Swelling?
Firstly, overcharging or excessive voltage can cause the electrolyte inside the battery to break down, leading to the production of gas. This gas buildup causes the battery to swell. To avoid this, it is essential to use a reliable and properly calibrated charger and adhere to the manufacturer’s recommended charging parameters.
Secondly, physical damage or puncturing of the battery can compromise its integrity. Even a small hole or crack can allow the electrolyte to escape, leading to swelling. Handling LiPo batteries with care, avoiding impact or crushing, and storing them in protective cases can help mitigate the risk of physical damage.
Additionally, exposure to high temperatures can accelerate the breakdown of the battery’s components, leading to increased gas production and subsequent swelling. It is crucial to store and operate LiPo batteries within the specified temperature range and avoid exposing them to extreme heat sources.
Furthermore, aging and prolonged use can also contribute to battery swelling. LiPo batteries have a limited lifespan and degrade over time. Regularly monitoring the battery’s health, including capacity and internal resistance, can help identify signs of degradation and prevent potential swelling issues.
Lastly, using counterfeit or low-quality batteries can increase the risk of swelling. It is essential to purchase LiPo batteries from reputable manufacturers and authorized sellers to ensure product quality, reliability, and adherence to safety standards.
In conclusion, LiPo battery swelling is a serious concern that should not be taken lightly. By understanding the reasons behind swelling and implementing preventive measures, such as proper charging practices, safe handling, and usage guidelines, we can maximize the lifespan and safety of LiPo batteries. Remember, your safety and the longevity of your devices rely on responsible battery management.
