Abstract
The present document describes a battery configuration for reducing electromagnetic interference (EMI). The battery configuration includes a coin cell (e.g., stacking battery cell, button cell) with predefined external-tab configurations and a predefined internal-tab angle for reducing electromagnetic (EM) coupling. In particular, internal tabs are positioned to be separated by an angle (e.g., a predefined internal-tab angle) of approximately 90 degrees. External tabs include (i) a first external tab connected to a side of the coin cell and extending to overlap a top surface of the coin cell and (ii) a second external tab connected to the top surface of the coin cell. Both external tabs are positioned relative to the internal tabs to reduce an H-field and/or an E-field created by current running through the coin cell.
