摘要： A negative active material thin film containing silicon as a main component is formed on a collector. A composition gradient layer, in which a composition distribution of a main component element of the collector and silicon is varied smoothly, is formed in the vicinity of the interface between the collector and the negative active material thin film. The composition gradient layer contains at least one kind of third element selected from W, Mo, Cr, Co, Fe, Mn, Ni, and P, in addition to the elements contained in the collector and the elements contained in the negative active material thin film. The third element irregularizes the atomic arrangement at the interface between the collector and the negative active material thin film. Therefore, even when the negative active material absorbs/desorbs ions during charging/discharging, thereby allowing silicon particles in the negative active material to expand/contract, the strain at the interface involved in the expansion/contraction of the silicon particles is alleviated, and peeling at the interface between the negative active material thin film and the collector is suppressed. Consequently, cycle characteristics are enhanced.

摘要： A negative active material thin film provided on a collector layer directly or via an underlying layer has a multi-layered configuration including at least two silicon thin films containing silicon as a main component. Because of this, even when the thickness of the negative active material thin film is increased, the increase in thickness of one silicon thin film can be prevented by increasing the number of silicon thin films. Thus, the diameter of silicon particles substantially in an inverse truncated cone shape is not enlarged in the silicon thin film. Accordingly, in an energy device having a thin film mainly containing silicon as a negative active material, even when the thickness of the negative active material layer is increased to obtain a larger capacity, cycle characteristics are not degraded.
摘要翻译： 直接或经由下层设置在集电极层上的负极活性物质薄膜具有包括至少两个以硅为主要成分的硅薄膜的多层结构。 因此，即使当负极活性物质薄膜的厚度增加时，也可以通过增加硅薄膜的数量来防止一个硅薄膜的厚度增加。 因此，在硅薄膜中，基本上呈倒圆锥形状的硅粒子的直径不会增大。 因此，在具有主要含有硅作为负极活性物质的薄膜的能量装置中，即使负极活性物质层的厚度增加以获得较大的容量，也不会降低循环特性。
