Abstract (AI)

Lithium-ion batteries (LIBs) are considered to be one of the most important energy storage technologies. As the energy density of batteries increases, battery safety becomes even more critical if the energy is released unintentionally. Accidents related to fires and explosions of LIBs occur frequently worldwide. Some have caused serious threats to human life and health and have led to numerous product recalls by manufacturers. These incidents are reminders that safety is a prerequisite for batteries, and serious issues need to be resolved before the future application of high-energy battery systems. This Review aims to summarize the fundamentals of the origins of LIB safety issues and highlight recent key progress in materials design to improve LIB safety. We anticipate that this Review will inspire further improvement in battery safety, especially for emerging LIBs with high-energy density.

Key Findings

Advances in materials design are expected to support safer high-energy and emerging lithium-ion battery technologies.

Battery safety is identified as a prerequisite for deploying future high-energy lithium-ion battery systems.

Increasing lithium-ion battery energy density heightens the consequences of unintended energy release and makes safety increasingly critical.

Lithium-ion battery fires and explosions occur frequently worldwide, posing serious threats to human health and causing numerous product recalls.

The review summarizes the fundamental origins of lithium-ion battery safety problems and recent materials-design strategies for improving safety.
