ABSTRACT:
The present invention relates to an improved electrochemical device, such as a primary cell battery, that is capable of being manufactured on the miniature-level (e.g., a size amenable to being used in an injectable medical apparatus). An exemplary electrochemical device comprises a header comprising a pin extending into an electrode space defined by the header and a device case. The pin also extends into a first electrode and is configured to be the current collector of the device. An electrode pressure plate is disposed adjacent a second electrode, and a pressure maintaining spring interfaces with the pressure plate and a device base. The pressure maintaining spring is configured to expand as the electrochemical device discharges, thereby maintaining a contact pressure within the device.
