Patent number: 7816032Abstract: 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.Type: GrantFiled: November 4, 2004Date of Patent: October 19, 2010Assignee: Panasonic CorporationInventors: Kazuyoshi Honda, Kiichiro Oishi, Yasuhiko Bito, Takayuki Nakamoto
