Abstract: The disclosed technology relates to a battery utilizing an indicator to orient an unopposed portion of a cathode or anode with respect to a battery can, and a tag to generate an electromagnetic field to mitigate or eliminate an electromagnetic field generated by the unopposed portion of the cathode or anode. The battery includes a wound set of layers including a cathode, an anode, and a separator; a can housing the wound set of layers; a lid disposed atop of the can to enclose the wound set of layers within the can; and a tag coupled to the lid. An unopposed portion of the cathode or anode generates a first electromagnetic field. The tag generates a second electromagnetic field to oppose the first electromagnetic field.
