1Cation-mixing stabilized layered oxide cathodes for sodium-ion batteries显示文摘Sodium-ion batteries are promising for large-scale energy storage due to sodium's low cost and infinite abundance. The most popular cathodes for sodium-ion batteries, i.e., the layered sodium-containing oxides, usually exhibit reversible host rearrangement between P-type and O-type stacking upon charge/discharge. Herein we demonstrate that such host rearrangement is unfavorable and can be suppressed by introducing transition-metal ions into sodium layers. The electrode with stabilized P3-type stacking delivers superior rate capability, high energy efficiency, and excellent cycling performance. Owing to the cation-mixing nature, it performs the lowest lattice strain among all reported cathodes for sodium-ion batteries. Our findings highlight the significance of a stable host for sodium-ion storage and moreover underline the fundamental distinction in material design strategy between lithium-and sodium-ion batteries.Shaohua Guo Yang Sun Pan Liu Jin Yi Ping He Xiaoyu Zhang Yanbei Zhu Ryosuke Senga Kazu Suenaga Mingwei Chen Haoshen Zhou 2018Science Bulletin2018,63,6:5
