Can the lithium battery still be used if it bulged?

There may be two reasons for the battery drum package. One is the problem of battery manufacturing level, the electrode coating is uneven, and the production process is rough. The second is the problem of overcharge and over discharge during use. These two factors lead to a violent reaction inside the battery that is close to a short circuit during the use of the battery, generating a large amount of heat, which leads to decomposition and gasification of the electrolyte, and the battery is bulged.

　If you have more than one battery, it should be that the cut-off voltage of the charger you are using does not match the battery. It is recommended to replace it.

　In addition, the bulging phenomenon occurs when the battery is not used for a long time, because the air is electrically conductive to a certain extent. Therefore, if the discharge time is too long, it is equivalent to direct contact between the positive and negative electrodes of the battery, and a chronic short circuit is performed.

　If the backup battery is not used for a long time, it is recommended not to fully charge the electricity. It is best to keep about 60% of the power. In addition, take it out after a while, which will benefit the battery life.

　The battery quality is poor and the charging time is too long. The battery charging drum cannot be used anymore and replace it with a new one as soon as possible.

　Different batteries can't be mixed, you must pay attention to it in the future, and when the battery is not in use, keep the battery full, otherwise, the battery life will be gone after 1-2 months.

　Mobile phone battery is a high-energy lithium battery. If there is a bulge and expansion, please do not continue to use it to avoid dangerous situations. At this time, please replace the battery in time!

　Mobile phone battery, the life of the use, generally used for one to two years, there will be problems afterwards, the problem is mainly due to improper use, the battery is not good quality, the structure is not perfect.

　The metal properties of lithium are destined to undergo an oxidation reaction when the bulge leaks into the air in contact with oxygen, which may cause an explosion.

　In fact, the charging and discharging of a lithium battery occurs in a chemical reaction. When charging, the lithium ion of the positive electrode loses an electron when it is charged, and becomes a lithium ion. Lithium ions swim through the lye to the negative electrode, then store and discharge, and vice versa, release a lithium ion and reduce it to lithium. Not durable because of internal consumption.

　There is a layer of diaphragm paper inside the battery. Good barrier paper can actively close the pores when the battery temperature is too high, so that lithium ions cannot pass through and prevent damage. But when the diaphragm is of poor quality, it will cause harm.

　This kind of situation usually occurs in the user's mobile phone of the detachable battery. Many users like to buy cheap non-original batteries. In order to maximize the profit, such battery manufacturers will cut corners. If the protection circuit is not safe, it will cause the battery cell to expand. For a lithium-ion battery, if the battery cell expands to a certain limit, it will cause an explosion. It is very dangerous. Please choose a regular factory-matched battery, although it is more expensive than others. But safe, you have to know that life is more than anything else.

　Usually, the situation that the charger causes a problem with the battery is the most common. Under normal circumstances, the user will not care much about the choice of his mobile phone charger. Often, as long as it can be used, it will be charged with a charger. These chargers are likely to be cheap chargers bought in informal places. There is no safe protection circuit device. The charging current is generally large. Occasionally, the charging problem is not very big, but it is used for charging for a long time. There may be an accident with battery expansion.

　Some users like to watch while charging the phone, so that the phone is running in a high temperature environment for a long time. Continuous charging will cause side reactions of the electrolyte inside. If this operation is performed for a long time, it will seriously affect the life of our mobile phone battery. It is easy to have problems with expansion. If our mobile phone is not used for a long time, the battery installed in the mobile phone will also expand. This is a long-term storage of the battery, so that the voltage will slowly drop below 2V, so that a chemical reaction will occur inside, which will cause the lithium battery of the mobile phone to become drum. This is why many users generally find out when disassembling old phones. Therefore, if you want to store the battery for a long time, the most reliable method is to periodically charge the battery to a half-filled state, which can extend its service life.

Once the problem of the mobile phone battery drum kit occurs, we must stop using it immediately. For its own safety, according to the model of its mobile phone, buy a safe power supply that matches the mobile phone. Remember: usually take good care of the mobile phone, don’t play while charging. . In the case of normal use, if there is a battery drum kit, please go to the network 315 platform complaints, there will be a special staff to deal with, such a situation, are some bad businesses, driven by the interests of illegal activities.
