Overview

This approach demonstrates enhanced anion storage capacity in graphite, indicating improved energy storage performance with multi-electron redox pathways.

Key Points

  • The research aims to enhance anion storage in graphite cathodes for dual-ion batteries by enabling multi-electron redox chemistry.
  • Developed iron‐chloride‐intercalated graphite
  • Studied the pre‐activated, cascade multi‐electron redox pathway
  • Evaluated oxidation processes of iron and chlorine
  • Measured performance metrics under various conditions.
  • Achieved an average transfer of 2.61 electrons per redox event
  • Delivered a stable capacity of 52 mAh g −1 at 3 A g −1
  • Outperformed conventional graphite cathodes with only 15 mAh g −1
  • Enabled operation up to 5 V (vs. Na/Na + ).
