Failure Analysis

Definition

Failure analysis is the systematic investigation of components, materials, or systems that fail or do not perform as expected. This process aims to identify the root causes of failure in order to prevent future occurrences and improve reliability, particularly in contexts such as solid-state batteries, where safety and efficiency are critical.
