A notification determinator determines whether or not an inspection result of a winding body indicates defective on the basis of whether or not continuous positions of a first end surface and a second end surface indicated by first group data and second group data are separated from reference positions by a predetermined distance or more. In a case where the inspection result of the winding body indicates defective, a notification determinator performs a notification that inspection in an inspection machine is not performed normally, and outputs information indicating that a cause of the defect is a take-out chuck of an inspection machine or any of a plurality of winding cores to a display for maintenance.

Template electrode structures for depositing active materials

Provided are examples of electrochemically active electrode materials, electrodes using such materials, and methods of manufacturing such electrodes. Electrochemically active electrode materials may include a high surface area template containing a metal silicide and a layer of high capacity active material deposited over the template. The template may serve as a mechanical support for the active material and/or an electrical conductor between the active material and, for example, a substrate. Due to the high surface area of the template, even a thin layer of the active material can provide sufficient active material loading and corresponding battery capacity. As such, a thickness of the layer may be maintained below the fracture threshold of the active material used and preserve its structural integrity during battery cycling.
