In situ measurements

Definition

In situ measurements refer to the assessment and evaluation of material properties or system performance conducted directly at the location where the materials or systems are used, rather than in a laboratory setting. This approach allows for real-time monitoring and analysis, providing insights into how materials behave under actual operating conditions, which is critical for understanding performance in energy storage technologies.
