In some examples, a battery assembly for an implantable medical device. The battery assembly may include an electrode stack comprising a plurality of electrode plates, wherein the plurality of electrode plates comprises a first electrode plate including a first tab extending from the first electrode plate and a second electrode plate including a second tab extending from the second electrode plate; a spacer between the first tab and the second tab; and a rivet extending through the first tab, second tab, and spacer, wherein the rivet is configured to mechanically attach the first tab, second tab, and spacer to each other.

Battery assembly for medical device

Aspects of this disclosure relate to a welding system that is configured to execute opposed, step, and parallel gap resistance spot welds (RSW) and associated methods. The system may be configured to switch bases to switch between an opposed weld configuration, a step weld configuration, and a parallel gap configuration. The system may include an accelerometer that is secured to the weld head adjacent one of the electrodes. The system may use the accelerometer to determine whether or not an RSW was defective. Acceleration data may indicate a defective weld when it includes acceleration data that is outside of a threshold range of acceptable acceleration data.

Resistance spot weld head with integrated accelerometer

A battery having an electrode assembly located in a housing that efficiently utilizes the space available in many implantable medical devices is disclosed. The battery housing includes a cover and a case. The electrode assembly includes an anode tab and a cathode tab that are coupled to the cover and to a feedthrough pin disposed on the cover. The coupling of the anode tab to the cover defines an anode terminal while the coupling of the cathode tab to the feedthrough pin defines the cathode terminal. The anode and cathode tabs are aligned with the feedthrough pin and the connection point at the cover such that the tabs and feedthrough pin overlap each other along a common plane that is perpendicular to a plane that is defined by a major surface of the cover.
