Ultra‐Long Cycle of Prussian Blue Analogs Achieved by Equilibrium Electrolyte for Aqueous Sodium‐Ion Batteries (Small 46/2023)

Prussian Blue Analogs Prussian blue analogs are suitable cathode materials for aqueous sodium-ion batteries, which contain interstitial water defects. The interstitial water is significant to the structural stability, but easy to lose. Through the equilibrium electrolyte, the lost interstitial water can be replenished timely to stabilize the framework.
