| 1 | Self-standing oxygen-deficient a-MoO_(3-x)nanoflake arrays as 3D cathode for advanced all-solid-state thin film lithium batteries显示文摘Compared with the planar two-dimensional(2D)all-solid-state thin film batteries(TFBs),threedimensional(3D)all-solid-state TFBs with interdigitated contact between electrode and electrolyte possess great advantage in achieving both high energy and power densities.Herein,we report a facile fabrication of vertically aligned oxygen-deficient a-MoO3-x nanoflake arrays(3D MO_(x))using metal Mo target by direct current(DC)magnetron sputtering.By utilizing the 3D MO_(x)cathode,amorphous lithium phosphorus oxynitride solid electrolyte,and lithium thin film anode,3D solid-state TFBs have been successfully fabricated,exhibiting high specific capacity(266 mAh g^(-1)at 50 mA g^(-1)),good rate performance(110 mAh g^(-1)at 1000mA g^(-1)),and excellent cycle performance(92.7%capacity retention after 1000 cycles)in comparison with the 2D TFBs using the planar MO_(x)thin film as cathode.The superior electrochemical performance of the 3D TFBs can be attributed to the 3D architecture of the cathode,maximizing the cathode/electrolyte interface while retaining the short Lit diffusion length.The charge/discharge measurements of the 3D MO_(x)cathode in liquid electrolyte,however,exhibit fast capacity fading,demonstrating the advantage of using transition metal oxide as cathode in solid-state batteries. | Shuo Sun Qiuying Xia Jizi Liu Jing Xu Feng Zan Jili Yue Serguei V.Savilov Valery V.Lunin Hui Xia | 2019 | Journal of Materiomics2019，5，2： | 6 |
