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...
