Technical FAQs 4

Are cylindrical lithium-ion batteries safe?

Though cylindrical batteries often incorporate safety devices, the safety of the battery also depends on its design and manufacturing processes. This study conducts a design and process failure mode and effect analysis (DFMEA and PFMEA) for the design and manufacturing of cylindrical lithium-ion batteries, with a focus on battery safety. 1.

Are lithium ion batteries safe?

Major safety concerns for lithium-ion batteries are thermal runaway and explosion. Thermal runaway is a phenomenon where exothermic reactions occur within the cell, leading to a rapid temperature increase, potentially causing the cell to catch fire .

Why do we need safety regulations for lithium ion batteries?

In such cases, the electrolyte acts as a fuel supply for further heat generation, so appropriate safety regulations, which can be established by researching the controllable and uncontrollable factors in battery failures, are essential for improving LIB safety performance.

What is a cylindrical lithium-ion battery?

Cylindrical lithium-ion batteries are complex systems with multi-step manufacturing processes. This introduces the possibility of diverse failure modes that detrimentally lead to a common effect, impacting the quality, reliability, and safety of the battery.
