Design Failure Mode and Effects Analysis (DFMEA) is a structured approach for identifying potential design-related failures of products and their implications. When applied to lithium-ion batteries, DFMEA offers a comprehensive understanding of the potential risks associated with their design, enhancing safety and reliability.
With the widespread use of lithium-ion batteries in various applications, ensuring their safety has become very essential. Incidents involving battery fires have raised safety concerns, necessitating a thorough assessment of potential failure modes during the design phase.
A reference degradation and aging mechanism shown below can be used to initiate a thorough DFMEA for the batteries under design and development.
