Na3.5(MnVFeTi)0.5(PO4)3: A Multi-Transition-Metal-Ion-Engineered NASICON-Type Cathodes for Sodium Ion Batteries
Electrochemically active Na-superionic conductor (NASICON)-type cathodes have the structural flexibility to include various transition elements, thus enabling high power outputs benefited by multi-electron redox reactions. This study amalgamated multiple transition metal ions to construct a new NASICON-type cathode i. e., carbon coated Na3.5(MnVFeTi)0.5(PO4)3 (NMVFTP/C) for Na-ion batteries (NIBs). The NMVFTP/C cathode engineered in this study demonstrated stable Na+-storage capacity, including long-term cycling stability up to 4000 cycles at 3000 mA g−1 with 96 % capacity retention and a high-rate output capacity of 85.16 mAh g−1 at 2500 mA g−1. To elucidate the ion transport process within the cathode, density functional theory modeling was employed. The low energy barrier for the diffusion of Na+ in the NMVFTP/C materials was proved to be a key factor supporting our material's superior electrochemical performances.
