Overview

Statistical analysis unveils variability in pouch cell characteristics, suggesting improvements for manufacturing quality control.

Key Points

  • Current demonstrates the highest variability at a mean of 0.280A, indicating process inconsistencies in battery production.
  • Voltage remains stable with a mean of 3.951V, while charge and discharge capacities show moderate variability, at approximately 47.99% and 52.53%, respectively.
  • Box plot and control chart analyses link outliers to production factors, emphasizing electrode preparation as crucial for reducing variability.
  • Integrating statistical insights into practical manufacturing considerations supports improved quality control and enhances lithium-ion battery reliability.
