6 FAQs about [Lithium ion battery safety concerns]

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.

Why is a lithium ion battery a hazard?

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. Physical damage to lithium-ion battery cells can allow the electrolyte inside to leak, which is another potential hazard risk.

Can lithium ion batteries explode?

And even when a lithium-ion battery fire appears to have been extinguished, it can reignite hours – or sometimes even days – later. Lithium-ion batteries can also release highly toxic gases when they fail, and excessive heat can also cause them to explode.

Why are lithium-ion battery fires difficult to handle?

Another factor that makes lithium-ion battery fires challenging to handle is oxygen generation. When the metal oxides in a battery’s cathode, or positively charged electrode, are heated, they decompose and release oxygen gas. Fires need oxygen to burn, so a battery that can create oxygen can sustain a fire.

What happens if you overcharge a lithium ion battery?

Overcharging and overheating: Overcharging a lithium-ion battery beyond its designed capacity can lead to overheating. Cycling and aging: Lithium-ion batteries degrade over time due to charge and discharge cycles.

What happens if a lithium ion battery fails?

In an uncontrolled failure of the battery, all that energy and heat increases the hazard risks in terms of fuelling a potential fire. The heat from lithium-ion battery failures can reach up to 400 degrees Celsius in just a matter of seconds, with peak fire temperatures being higher than this.
