摘要
En 中文
To enable high performance of all solid-state batteries, a catholyte should demonstrate high ionic conductivity, good compressibility and oxidative stability. Here, a LaCl3-based Na+ superionic conductor (Na1 - x Zr (x) La1 - x Cl-4) with high ionic conductivity of 2.9 x 10(-4) S cm(-1) (30 degrees C), good compressibility and high oxidative potential (3.80 V vs. Na2Sn) is prepared via solid state reaction combining mechanochemical method. X-ray diffraction reveals a hexagonal structure (P6(3) /m) of Na1 - x Zr (x) La1 - x Cl-4, with Na(+ )ions forming a one-dimensional diffusion channel along the c-axis. First-principle calculations combining with X-ray absorption fine structure characterization etc. reveal that the ionic conductivity of Na1 - x Zr (x) La1 - x Cl-4 is mainly determined by the size of Na+-channels and the Na+/La3+ mixing in the one-dimensional diffusion channels. When applied as a catholyte, the NaCrO2||Na(0.7Z)r(0.3)La(0.7)Cl(4)||Na3PS4||Na2Sn all-solid-state batteries demonstrate an initial capacity of 114 mA h g(-1) and 88% retention after 70 cycles at 0.3 C. In addition, a high capacity of 94 mA h g(-1) can be maintained at 1 C current density.
