Solid State Synthesis Method

A novel cathode material with Ti-substitution on Ni site, P2-type Na0.67Ni0.25Ti0.08Mn0.67O2 has been synthesized via solid-state synthesis method and characterized electrochemically. Na0.67Ni0.25Ti0.08Mn0.67O2 electrodes have been observed tobe highly reversible at higher voltage ranges. The electrodes have an initial discharge capacity of 125 mAhg-1and can retain around 84% of this capacity (105 mAhg-1) even after 50 cycles at 0.1C when cycled at an uppercut-off voltage of 4.3 V. Na0.67Ni0.25Ti0.08Mn0.67O2 electrodes are believed to suppress the irreversible P2-O2 transformation by diverting the charging reaction through a more reversible P2-OP4transition.
