AI Technical Summary
Existing sodium-ion batteries have shortcomings in terms of high power performance, cycle stability, safety, and cost, and cannot meet the requirements for fast charging and efficient operation.
Fe-based and/or Mn-based polyanionic cathode materials with NASICON structure and sodium titanium phosphate anode materials coated with sulfur and nitrogen doped double carbon layers are used to construct long-range ordered structures and three-dimensional conductive networks through rheological phase reaction and NaCl-KCl eutectic salt synergistic sintering, thereby optimizing electron and ion transport.
It significantly improves the fast-charging efficiency of sodium-ion batteries, reduces constant-voltage charging time, enhances cycle stability and safety, and lowers costs.
