Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might have been a recent change in the manufacturing process. Has there been any modification to the production line or materials used in the past month?

Why it matters: Changes in production could directly impact energy density. Expected answer: Yes, there was a change in the sulfur supplier. Impact on approach: If confirmed, we'd focus on supplier quality control and material specifications.

• Considering the specificity of the 15% decrease, I'm curious about the testing methodology. Has there been any change in how we measure or calculate energy density recently?

Why it matters: Ensures we're comparing apples to apples in our measurements. Expected answer: No changes in measurement methodology. Impact on approach: If unchanged, we'd focus on actual performance issues rather than measurement discrepancies.

• Given the prototype nature, I'm wondering about the consistency of results. Are we seeing this 15% decrease across all prototype units or is it limited to a specific batch?

Why it matters: Helps determine if it's a systemic issue or isolated to certain units. Expected answer: The decrease is observed across all recent prototypes. Impact on approach: If widespread, we'd look at common factors affecting all units rather than isolated incidents.

• Thinking about external factors, have there been any significant changes in environmental conditions during testing, such as temperature or humidity?

Why it matters: Environmental factors can significantly impact battery performance. Expected answer: No notable changes in testing conditions. Impact on approach: If conditions are stable, we'd focus more on internal factors and material properties.
