Development of the Mg Secondary Batteries Using Anion Intercalation/de-intercalation Reaction into/out of the Graphite Electrode

Key Points

• This research aims to explore the anion intercalation/de-intercalation reactions in graphite electrodes for magnesium secondary batteries.
• Investigated anion intercalation/de-intercalation reactions in graphite.
• Varying electrolyte concentrations to understand their effects on reaction barriers.
• Utilized a diluted electrolyte to maintain coordination states in high-concentration solutions.
• Achieved a discharge curve with an average voltage of 3.5 V (vs. Mg2+/Mg).
• Identified that reaction barriers shift depending on electrolyte concentration.
