As we know the excellent performance of sodium ion battery depends deeply on the different type and preparation of anode / cathode material . while the effective research on anode material has already been done , study of cathode material with good electrochemical performance has become a key factor 鈉離子電池的優(yōu)異性能在很大程度上取決于正、負(fù)極材料的選擇和制備,在當(dāng)前負(fù)極材料的研究取得良好進(jìn)展的前提下,獲得鈉離子嵌入/脫嵌性能良好的正極材料成為該類電池發(fā)展的一個關(guān)鍵。
