Low noise battery with a magnetic compensation structure for wireless mobile communication device

An apparatus comprising:

• an electrode assembly, for providing electrical power, includes a positive electrode, a negative electrode, a positive tab electrically connected to the positive electrode, a negative tab electrically connected to the negative electrode, and a layer of electrolyte between the positive electrode and the negative electrode, wherein an electric current flow in the positive electrode is unmatched to an electric current flow in the negative electrode thereby producing a first magnetic field;
• and
• a magnetic compensation structure comprising a body of electrically conductive material electrically connected to one of the positive electrode and the negative electrode, a first compensation conductor electrically connected to the body, and a second compensation conductor electrically connected to the body, wherein the first and second compensation conductors are spaced from the positive tab, the positive electrode, the negative tab, and the negative electrode, and wherein an electric current flow from the electrode assembly through the body produces a second magnetic field that opposes the first magnetic field.

An apparatus, for providing electrical power, comprising:

• an electrode assembly having a positive electrode, a negative electrode, a layer of electrolyte between the positive electrode and the negative electrode, wherein an electric current flows through the positive electrode in a first pattern and flows through the negative electrode in a second pattern that is unmatched to the first pattern, resulting in an unmatched current pattern in a section of the electrode assembly;
• and
• a magnetic compensation structure adjacent to the electrode assembly and comprising a body of conductive material spaced from the electrode assembly, a first compensation conductor electrically connected to the body, and a second compensation conductor electrically connected to the body with one of the first compensation conductor and the second compensation conductor electrically connected to one of the positive electrode and the negative electrode, wherein a pattern of current flowing through the body matches the unmatched current pattern in the section of the electrode assembly.
