What are the issues with lithium battery energy storage

What are the main concerns about lithium-ion batteries?

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

What should you avoid when storing lithium-ion batteries?

Correct usage and storage of lithium-ion batteries is extremely important. Batteries should not be exposed to high external temperatures, for example from being left in direct sunlight for long periods of time. Overcharging is another fundamental issue as this can create excessive heat inside the battery cell.

How should lithium-ion batteries be stored?

Lithium-ion batteries should be stored in cool places and away from direct sunlight. They should not be exposed to high external temperatures. Additionally, overcharging should be avoided as it can create excessive heat inside the battery cell.

Why are lithium-ion batteries important?

Efficient and reliable energy storage systems are crucial for our modern society. Lithium-ion batteries (LIBs) with excellent performance are widely used in portable electronics and electric vehicles (EVs), but frequent fires and explosions limit their further and more widespread applications.

Are lithium ion batteries dangerous?

As the number of installed systems is increasing, the industry has also been observing more field failures that resulted in fires and explosions. Lithium-ion batteries contain flammable electrolytes, which can create unique hazards when the battery cell becomes compromised and enters thermal runaway.

What causes lithium-ion batteries to fail?

Overheating and physical damage are the main causes of lithium-ion battery failures. Excessive heat, often due to overcharging or short circuits, can damage the battery cell internally and cause it to fail.
