Why did lithium batteries catch fire

Why did lithium batteries catch fire



From common electronic products such as mobile phones and cameras to lithium batteries used in transportation. Behind the large-scale application, people are also concerned about its security.




To understand why lithium batteries catch fire, we need to first understand the composition and working principle of lithium batteries.



1. Lithium ion battery components: positive electrode material, separator, negative electrode material, organic electrolyte, battery shell




2. The working principle of lithium batteries is to store energy in a chemical form and release energy in electronic form through a series of electrochemical reactions.




3、 Why lithium batteries catch fire



(1) One of the main reasons for internal fires in lithium-ion batteries is due to damage to the separator, resulting in short circuits.




(2) Another main reason for lithium battery explosion and fire is Thermal runaway.




Therefore, for lithium battery manufacturers, it is very necessary to take necessary and sufficient safety precautions in production. For users, improper maintenance can also lead to accidents, so it is necessary to follow the requirements for using lithium batteries.
