Introduction to the use of lithium batteries safety

Lithium Battery

At present, lithium-ion batteries are widely used in electronics, communications, health care and other products, and play an important role in new energy storage, aerospace, electric bicycles, power tools and military and other fields. Lithium-ion battery is a kind of storage battery with the advantages of small size, easy to carry, large energy ratio, long service life and low self-discharge rate.lithium ion battery assembly

Lithium batteries are mainly divided into two main categories, namely lithium metal batteries and lithium ion batteries. Among them, lithium metal battery is a new type of battery born in 1996, its safety, specific capacity and self-discharge rate are better than the early lithium-ion batteries, but only a few countries are able to manufacture such batteries. Lithium-ion batteries are sold in the market.

Lithium atoms are the lightest alkali metal element, which can cause fire, explosion and other safety hazards if not used properly. To prevent possible safety problems associated with the use of lithium-ion batteries, precautions have been taken in the storage structure and construction of the case for lithium-ion batteries to prevent damage to the case and large amounts of oxygen from entering the case and causing an explosion. Lithium-ion batteries have high technical requirements for charging and discharging. Overcharging or overdischarging may cause the case to crack and explode. In addition, lithium-ion battery manufacturing process, shell welding, the use of ambient temperature and other requirements are relatively high, the production or use of inadvertent may bring potential safety hazards, and even bring great harm to people and property.battery cell machine

The safety testing of lithium batteries should not be ignored.

The real cause of cell phone explosion is caused by lithium batteries. Therefore, lithium batteries need us to go through a lot of tests before putting money into use, and simulate the abuse of lithium batteries may encounter in the market situation, in order to test the safety of the battery in use.

Lithium batteries in use in addition to external pressure and extrusion caused by shell damage caused by the explosion, but also due to improper charging caused by the explosion. For example, in the case of a short circuit in the power supply of a cell phone, due to the internal resistance of the battery itself is very small, the short-circuit immediately after the current is very large, resulting in a violent explosion of the battery heat.prismatic cell assembly

At present, the use of lithium batteries made of high-capacity rechargeable treasure is very popular with consumers. Because the larger the lithium capacity of the rechargeable treasure, the more power stored, the use of the security risks will increase. If you carry a rechargeable treasure when squeezing or dropping the shell, it may cause an explosion, and the larger the lithium battery capacity, the greater the power of the explosion. Especially on the airplane, lithium battery explosion will endanger the lives of all passengers. In recent years, due to the explosion of lithium batteries carried by passengers on airplanes caused by air crashes have occurred repeatedly. For this reason, the civil aviation departments of many countries around the world have strict regulations on the capacity and number of lithium battery products such as rechargeable batteries carried by passengers, in order to ensure the flight safety of the airplane.

Playing with cell phones while charging is harmful

Cell phone owners often can not stand the "loneliness" in the charging process, will always use the phone, which in fact is not conducive to safe behavior!

Using a smartphone while charging is likely to cause a short circuit in the power supply of the phone and cause electric shock, because in the process of charging management, making a phone call or surfing the Internet will make the cell phone's working circuit become more complex, which in turn can increase the risk of a cell phone circuit short-circuiting or error, and easy to electric shock.

Your cell phone can get feverish when charging. When charging a cell phone for surfing the Internet or receiving calls, the working circuits of the cell phone will generate heat along with the central processor, which can easily cause the temperature of the lithium-ion battery to rise rapidly, which in turn can cause an explosion or combustion.

Charging time and frequency will affect the battery life. Many cell phones will cut off the charging circuit from time to time when answering a call during the charging process, resulting in frequent charging, which will affect the battery life as the charging time increases.

So how do you use it safely?

Don't wait until the battery is completely drained before charging your phone.

Don't fully charge the battery, especially if we don't use a one-time charge from a very low percentage.

Try to keep the battery between 45% and 75%.

Don't use a non-original charger for a long time and don't charge without power.

Do not play with your cell phone while charging.
