Overview

This research demonstrates capacity loss modeling in lithium iron phosphate cells, suggesting key causes of capacity fade.

Key Points

  • Results indicate significant capacity loss in lithium iron phosphate cells due to high temperatures and transition metal dissolution.
  • Novel capacity loss model accurately predicts fade in lithium iron phosphate cells when compared to traditional models.
  • Modeling accounted for lithium inventory loss and identified solid electrolyte interphase growth as a primary cause of capacity loss.
  • Findings reveal important implications for enhancing the longevity of lithium iron phosphate batteries in energy storage applications.
