A Fast and Highly Stable Aqueous Calcium‐Ion Battery for Sustainable Energy Storage
ChemSusChem, Volume 18, Issue 6, March 15, 2025.Aqueous batteries provide a low‐cost, safer alternative to lithium‐ion batteries, but their viability is often limited by rapid electrode degradation. This study shows that replacing K+ with divalent Ca2+ ions in the electrolyte significantly boosts the stability of both copper hexacyanoferrate cathodes and polyimide anodes, enabling fast‐charging ...
