设计并构建了一套薄膜全固态锂电池全真空（in-vacuum）制备与评价系统。为了制备清洁的固体电解质/电极界面，用于阴极、电解质和阳极薄膜沉积的超高真空（UHV）室彼此直接连接。因此，在整个制造和评估过程中，样品保持在UHV条件下，不暴露于空气。薄膜锂电池，具有干净和良好定义的固体电解质/电极界面，表现出非常好的电化学性能，即使没有沉积后退火。这种性能归因于在真空中制备的清洁固体电解质/电极界面。(C)2015 Elsevier B. V.版权所有。
An all-in-vacuum (in-vacuo) fabrication and evaluation system for thin-film all-solid-state lithium batteries was designed and constructed. To prepare clean solid electrolyte/electrode interfaces, ultra-high-vacuum (UHV) chambers for the deposition of cathode, electrolyte, and anode thin films were directly connected to each other. Thus, throughout the fabrication and evaluation, the samples were maintained under UHV conditions, not exposed to air. The thin-film lithium battery, with a clean and well-defined solid electrolyte/electrode interface, exhibited very good electrochemical properties even without post-deposition annealing. This performance is attributed to the clean solid electrolyte/electrode interface prepared in the vacuum. (C) 2015 Elsevier B.V. All rights reserved.
