Lithium Battery Thermal Runaway Caused by Nail Penetration – Part 1
In recent years, the global energy crisis and environmental pollution have become increasingly serious. As a clean and pollution-free energy storage, lithium-ion batteries are gradually applied to new energy vehicles, solar energy conversion energy storage equipment, mobile communication equipment and other fields. At present, new energy vehicles with lithium-ion batteries appear in more and more cities, but some potential safety hazards are gradually exposed. According to the fire investigation report of new energy vehicles, the vast majority of fires are caused by the battery heat out of control. Improper use, accidental damage or defects of lithium-ion batteries may lead to explosion and fire. Among many reasons that trigger the thermal runaway of the battery, acupuncture is an irreversible destructive behavior that causes the battery damage. When the battery is pierced by sharp objects or subjected to a large impact force, it will cause mechanical damage to the ba...
