Method for electrode design for implantable device applications that require the elective replacement indicator (ERI)

摘要

A method for providing a physician with an elective replacement indicator (ERI) for an implantable medical device is described. The medical device is powered by an electrochemical having a lithium anode coupled to a sandwich cathode comprising the configuration: SVO/current collector/CF_x, with the SVO facing the anode. The indicator is predicated on when the cell's discharge capacity is nearing end-of-life (EOL) based on the theoretical capacity and the discharge efficiency of the SVO and CF_x active materials. This serves as an indicator when it is time to replace the medical device.
