Is lithium-ion battery energy storage safe?

Large-scale, commercial development of lithium-ion battery energy storage still faces the challenge of a major safety accident in which the battery thermal runaway burns or even explodes. The development of advanced and effective safety prevention and control technologies is an important means to ensure their safe operation.

Are lithium-ion batteries a good energy storage carrier?

In the light of its advantages of low self-discharge rate, long cycling life and high specific energy, lithium-ion battery (LIBs) is currently at the forefront of energy storage carrier [4, 5].

What happens if a lithium ion battery goes bad?

Lithium-ion batteries are electro-chemical energy storage devices with a relatively high energy density. Under a variety of scenarios that cause a short circuit, batteries can undergo thermal-runaway where the stored chemical energy is converted to thermal energy. The typical consequence is cell rupture and the release of flammable and toxic gases.

Can a lithium ion battery operate outside its intended temperature range?

Allowing a lithium ion battery to perform outside its intended operating temperature range can have detrimental effects on safety possibly leading to fire or explosion. To operate efficiently, grid supporting BESS (also called “in front of the meter” applications) are installed within close proximity or at sub-stations.

What happens if a lithium battery is thermal runaway?

As the energy storage lithium battery operates in a narrow space with high energy density, the heat and flammable gas generated by the battery thermal runaway cannot be dissipated in time, which will further cause the battery temperature to rise, and when the temperature exceeds safety threshold, the battery will burn or explode [25, 26].

Why are lithium-ion batteries used in electrochemical energy storage technology?

It is well known that lithium-ion batteries (LIBs) are widely used in electrochemical energy storage technology due to their excellent electrochemical performance. As the LIBs energy density is become more and more demanding, the potential electrode material failure and external induced risks also increase.
