Are lithium-ion cells and batteries safe?

Lithium-ion cell and battery safety has recently emerged as a major topic of research and development work. This chapter will focus on identifying the leading safety hazards in a lithium-ion cell and battery, defining the currently taken pathways to address these hazards and highlighting the possible future safety solutions.

Are Lib batteries safe?

The greater energy density of batteries and more LIB packs mean greater potential of safety risks. Taking Tesla EV as an example, more than 20 cars of the Model X/S series suffered battery thermal runaway accidents during 2018–2019 . In short, the safety of LIBs is crucial to the development of EVs.

Are libs safe?

However, the safety issues of LIBs such as fire and explosion have been a serious concern. It is important to focus on the root causes of safety accidents in LIBs and the mechanisms of their development. This will enable the reasonable control of battery risk factors and the minimization of the probability of safety accidents.

What factors affect the safety of on-board lithium ion batteries?

In this review, we analyzed the main causes of the safety risks of LIBs and examined the inherent electrochemical mechanisms of LIBs. We also summarized the main factors that affect the safety of on-board LIBs, including battery materials, design, abuse conditions, and battery status.

What is the future of lithium-ion battery design?

Safety-related cell and battery design challenges are most likely to be the leading topic for research and development in the next 5–10 years. The field of the cell chemistry development remains very prolific and new materials for lithium-ion battery applications are reported almost every day.

Is a lithium ion cell assembly safe?

Batteries become an integrated part of the vehicle structure, and lithium ion cell assembly is safety-critical. In every step of the assembly process you have to use smart and secure joining technologies “Atlas Copco has found innovative ways of handling all types of joining within the battery pack,” Tibblin says.
