Title
(EN) SOLID SECONDARY BATTERY AND METHOD FOR MANUFACTURING SAME
(FR) BATTERIE SECONDAIRE SOLIDE ET SON PROCÉDÉ DE FABRICATION

Abstract
(EN)
Provided are: an all-solid secondary battery, specifically a thin-film solid secondary battery, having higher safety than conventional lithium ion secondary batteries that use an electrolytic solution; and a method for manufacturing the same. According to the present invention, a mixed material obtained by codeposition of SiO and a lithium organic complex is used as a solid electrolyte. In other words, a solid electrolyte layer comprising a mixed material of an inorganic material and an organic material is used in a solid secondary battery. The ratio of oxygen to silicon in the solid electrolyte layer is greater than 1 but less than 2.
(FR)
L'invention concerne : une batterie secondaire entièrement solide, plus spécifiquement une batterie secondaire solide à film mince, ayant une sécurité supérieure à celle des batteries secondaires au lithium-ion classiques qui utilisent une solution électrolytique; et un procédé de fabrication de celle-ci. Selon la présente invention, un matériau mixte obtenu par dépôt simultané de SiO et d'un complexe organique de lithium est utilisé en tant qu'électrolyte solide. En d'autres termes, une couche d'électrolyte solide comprenant un matériau mixte d'un matériau inorganique et d'un matériau organique est utilisée dans une batterie secondaire solide. Le rapport d'oxygène par rapport au silicium dans la couche d'électrolyte solide est compris entre 1 et 2.
(JA)
電解液を用いる従来のリチウムイオン二次電池よりも安全性の高い全固体二次電池、具体的には薄膜型の固体二次電池及びその作製方法を提供する。 固体電解質としてSiOと、リチウムの有機錯体との共蒸着で得られる混合材料を用いる。即ち、無機材料と有機材料の混合材料からなる固体電解質層を固体二次電池に用いる。固体電解質層のシリコンに対する酸素の比は、1より大きく2より小さい。
