Breaking the High-Voltage Limit of Na2CO3 Presodiation: An Interfacial Engineering Approach to Ampere-Hour Sodium-Ion Devices

Abstract Na2CO3 is a promising sacrificial presodiation agent owing to its high capacity, excellent air stability, and low cost. However, its practical application is severely hampered by a high decomposition overpotential (>4.3 V vs Na/Na+), inducing detrimental electrolyte oxid...

New Insights into the Structural Stability of Carbonyl Sodium-Storage Anodes Based on Janus Dione

Abstract Developing advanced sodium-storage electrodes is of great importance for the advancement of sodium-ion batteries; herein, s-indacene-1,3,5,7(2H,6H)-tetraone (ICTO) is employed for the first time as an anode material for sodium-ion batteries (SIBs). By converting anhydrid...
