Redox-active potassium iodide boosts ion storage efficiency in solid cementitious electrolyte toward energy-storing concrete

Key Points

• Enhanced ion storage efficiency was observed in cementitious electrolytes with potassium iodide.
• The integration resulted in a significant increase in the energy storage capacity of concrete by 30%.
• Assessment of ion storage properties in solid cementitious electrolytes demonstrated superior performance compared to standard formulations.
• These findings imply a shift toward more efficient energy storage solutions in construction materials.
