Known Application

1.Sodium-Ion Batteries: Used as a sacrificial presodiation additive to compensate for irreversible sodium loss during initial battery cycling, potentially improving the initial Coulombic efficiency and usable capacity. 2.Sodium-Ion Capacitors: Can serve as a sodium source for presodiation, helping compensate for sodium consumption during electrochemical processes. 3.Advanced Functional Materials: The squarate anion can participate in coordination chemistry, making sodium squarate a potential precursor for research into coordination compounds and other functional materials.

Advantages

1.High Theoretical Presodiation Capacity: Offers a theoretical irreversible specific capacity of approximately 339 mAh/g, providing potential for efficient sodium compensation. 2.Improved Initial Coulombic Efficiency: Helps compensate for sodium consumed by irreversible reactions during the first charge, potentially improving initial battery efficiency. 3.Enhanced Sodium Utilization: May help improve available capacity by reducing the impact of irreversible sodium loss in full-cell systems. 4.Flexible Electrode Formulation: Can be incorporated into electrode formulations as a sacrificial additive, subject to compatibility with the electrode materials and processing conditions. 5.Research-Backed Applications: Has been investigated for presodiation in sodium-ion batteries and sodium-ion capacitors.
