The use of lithium-ion batteries in electronics is a hot topic these days because of its advantages over other types of batteries. However, before using lithium-ion batteries to make technical devices work; they go through a process of testing and verification, which makes it clear that the possibility of danger can be reduced.
Here are several reasons why lithium-ion batteries undergo rigorous safety testing:
Travel test
All lithium-ion batteries manufactured go through a series of transport tests according to safety standards. During the travel test process, the battery is kept at different temperatures that mimic the effects of the travel environment.
Safety testing and certification
Safety testing and certification of lithium-ion batteries includes many different durability tests, such as extreme temperature, voltage, and current. This type of test ensures that all lithium-ion batteries that perform the procedure are not safe to meet the battery safety certification standard.
Electrical test
Electronic testing ensures that any device powered by a lithium-ion battery will not operate under severe electromagnetic interference. The testing process ensures that all devices powered by lithium-ion batteries will not produce electromagnetic interference (EMI) themselves. Wide application of lithium batteries in life
Wide application of lithium batteries in life
Lithium ion batteries are used in technical electronics, due to their advantages and compatibility with many electronic devices.
The quality of lithium-ion batteries differs from each other and their shape which indicates the amount of energy they can produce.
Some applications of lithium-ion batteries include:
1. UPS
2. Mobile phones, laptops
3. and watches
4. Energy system
5. Cars etc.
Principles of operation of lithium batteries
The composition of lithium-ion batteries is different from each other. Even so, regardless of size, lithium-ion batteries use elements such as anode, cathode, separator, and electrolyte. An electrolyte is a lithium salt in an unstable organic solvent that requires the combination of lithium and oxygen to form a stable compound called lithium oxide.
The cathode inside a lithium battery is what determines the battery’s characteristics. This is an indicator of the strength and voltage of the battery will depend on the lithium-ion coating and cathode. The higher the lithium ion coating and cathode, the higher the battery capacity and voltage will be. Another element in the lithium-ion battery is the separator, which keeps the cathode and anode separate from each other for safety in the entire process.
Why lithium batteries explode
Reasons for Lithium Batteries to Explode There are many factors that can cause a lithium-ion battery to explode. In most cases, the problem is a short circuit when the separator does not keep the cathode and anode inside the battery from touching. As soon as the cathode and anode in the lithium-ion battery touch, it will start to heat up both the battery and the electrical equipment.
Here are the reasons why the battery compartment may fail:
Bad battery configuration
If the battery is not properly installed the separator is not properly placed in the intended area. This can cause the battery to explode as the sides of the battery expand and separate if charged, allowing both the cathode and anode to touch.
External factors
External factors affecting the lithium battery can cause it to explode, whether it is weather conditions or other physical effects.
Although lithium batteries fail and explode from time to time. Lithium-ion battery testing methods are very safe to use in electronic devices, once they have completed the correct testing process.
The importance of lithium battery safety testing
Using a lithium battery safety test has many benefits, including:
Low maintenance
Lithium batteries do not require these types of maintenance, only requiring the user to maintain them under specific environmental conditions.
Sustainable
Lithium-ion batteries can last for a long time without any effect or failure for 8 years or more.
Ability to pay quickly
Lithium-ion batteries can be fully charged in a short time, due to their fast charging capabilities.
How to test lithium battery safety
The lithium battery safety test is a process where the battery is placed in an environmental test machine that simulates different outdoor temperatures. An example of a lithium battery installed in a test machine can be damaged after each test cycle, because in the environmental test machine, the temperature can range from very cold to hot depending and experimental methods presented. Procedures during testing include voltage testing, internal resistance testing, etc.
