Abstract

Developing multielectron reaction electrode materials is essential for achieving high specific capacity and high energy density in secondary batteries; however, it remains a great challenge. Herein, Na ₃ MnTi(PO ₄ ) ₃ /C hollow microspheres with an open and stable NASICON framework are synthesized by a spray-drying-assisted process. When applied as a cathode material for sodium-ion batteries, the resultant Na ₃ MnTi(PO ₄ ) ₃ /C microspheres demonstrate fully reversible three-electron redox reactions, corresponding to the Ti ^3+/4+ (≈2.1 V), Mn ^2+/3+ (≈3.5 V), and Mn ^3+/4+ (≈4.0 V vs Na ⁺ /Na) redox couples. In situ X-ray diffraction results reveals that both solid-solution and two-phase electrochemical reactions are involved in the sodiation/desodiation processes. The high specific capacity (160 mAh g ⁻¹ at 0.2 C), outstanding cyclability (≈92% capacity retention after 500 cycles at 2 C), and the facile synthesis make the Na ₃ MnTi(PO ₄ ) ₃ /C a prospective cathode material for sodium-ion batteries.
