Technical FAQs 3

What is DFMEA in battery design and development?

A reference degradation and aging mechanism shown below can be used to initiate a thorough DFMEA for the batteries under design and development. Design Failure Mode and Effects Analysis (DFMEA) is a structured approach for identifying potential design-related failures of products and their implications.

Why is DFMEA important for lithium-ion batteries?

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.

How does DFMEA PFMEA affect battery safety?

From the integrated DFMEA–PFMEA, we have identified that localized heating and a short circuit increase the risk of thermal runaway, whereas increased gas generation due to moisture or electrolyte leakage increases the risk of explosion. Manufacturing and assembling defects in the safety devices also reduce the safety of the battery.
