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.

Why are lithium ion batteries used in portable electronics?

In addition, the battery market for portable electronics is currently dominated by LIBs because of their inherent advantages over other battery systems, such as high specific capacity and voltage, no memory, excellent cycling performance, little self- discharge, and wide temperature range of operation , .

Are lithium batteries dangerous?

This battery was equipped with a LiCoO2 cathode element, and the anode was graphitic carbon. Soon after, one of these Li-ion batteries (LIBs) exploded in hand-held video cameras. Since then, the safety issue associated to the risk of thermal runaway and battery fire is known to be a major problem of the lithium batteries. This is also costly.

How does a lithium ion cell work?

The working concept of a lithium-ion cell is explained by its relationship with the temperature. The mechanisms of the thermal runaway event in a cell are detailed and associated with the different exothermic reactions. A comprehensive review of electrical, mechanical and thermal abuse testing is proposed.

What are the abuse tests for lithium-ion batteries?

The main abuse tests (e.g., overcharge, forced discharge, thermal heating, vibration) and their protocol are detailed. The safety of lithium-ion batteries (LiBs) is a major challenge in the development of large-scale applications of batteries in electric vehicles and energy storage systems.

Why is battery safety testing important?

To analyse the root causes of detects of LiBs, battery safety testing has been developed. They are designed to recreate an abusive environment that represents a cell during an accident.
