This paper reports the effects of introducing oxygen into amorphous silicon films on their anode properties in all-solid-state lithium batteries. Although poor cycling performance is a critical issue in silicon anodes, it has been effectively improved by introducing even a small amount of oxygen, that is, even in Si-rich amorphous silicon suboxide (a-SiOx) films. Because of the small amount of oxygen in the films, high cycling performance has been achieved without lowering the capacity and power density: an a-Si film delivers discharge capacity of 2500 mAh g(-1) under high discharge current density of 10 mA cm(-2) (35 C). These results demonstrate that a-SiOx, is a promising candidate for high-capacity anode materials in solid-state batteries. (C) 2016 Elsevier B.V. All rights reserved.
