논문 초록 (Abstract)
Unstable and deficient supplies of lithium resources have led to the development of alternative battery systems such as sodium-ion batteries. Herein, P-type Na 0.6 Mn 0.65 Ni 0.25 Co 0.10 O 2 cathode materials were synthesized by a co-precipitation and solid-state reaction method. When the calcination temperature was changed from 700 to 1000 C, Na 0.6 Mn 0.65 Ni 0.25 Co 0.10 O 2 had a different morphology and crystalline structure; however, a P3-type structure was formed only at 700 C, and P2-type structured cathodes could be obtained at 800, 900, and 1000 C. Their electrochemical performances were evaluated with 2032 coin-type half cells. Among them, the P2-type cathode calcinated at 900 C, exhibited a high specific discharge capacity of 148 mAh g− 1, and a stable cycling performance at a 0.2 C rate for 150 cycles.
