What happens if a lithium-ion battery fails?

In addition to this, the way a lithium-ion battery produces power also generates heat as a by-product. In an uncontrolled failure of the battery, all that energy and heat increases the hazard risks in terms of fuelling a potential fire.

Do vibrations and shocks affect Li-ion batteries?

As Li-ion batteries become more common, research is needed to determine the effect of standard vibration and shock tests as well as that of long-term vibration on battery cells. Accordingly, studies on the effect of vibrations and shocks on Li-ion battery cells have been recently conducted.

Are lithium-ion batteries safe?

However, they are also susceptible to causing potentially catastrophic fire events. Image from Shutterstock Lithium-ion batteries are the most widespread portable energy storage solution – but there are growing concerns regarding their safety.

What happens if a lithium ion battery overheats?

The major issue with lithium-ion batteries overheating is a phenomenon known as thermal runaway. In this process, the excessive heat promotes the chemical reaction that makes the battery work, thus creating even more heat and ever more chemical reactions in a disastrous spiral.

How does a lithium ion rechargeable battery work?

A typical lithium-ion rechargeable battery. The battery consists of a positive electrode (green) and a negative electrode (red), with a layer (yellow) separating them. When in use, lithium-ions (Li+, blue) travel from the negative electrode (anode) to the positive (cathode).

Why are lithium-ion batteries more popular?

However, lithium-ion batteries are more useful and therefore much more popular as they combine fast charging, long charge holding and high-power density, for more battery life in a smaller package.
