Abstract:
1. An apparatus comprising: an electrode assembly including a positive electrode connected directly to a positive tab, and including the negative electrode spaced from the positive electrode and connected directly to a negative tab; a layer of electrolyte between the positive electrode and the negative electrode, for producing an electric current between the negative electrode and the positive electrode; and a magnetic compensation structure proximate to the electrode assembly and comprising: (a) a base of electrically conductive material; (b) a first conductor electrically connected to the base and spaced from the positive tab and the positive electrode, a first ratio of two dimensional conductivity between the first conductor and the base being substantially similar to a second ratio of two dimensional conductivity between the positive tab and the positive electrode; (c) a second conductor electrically connected to the base and spaced from the second conductor, negative tab and the negative electrode, a third ratio of two dimensional conductivity between the second conductor and the base being substantially similar to a fourth ratio of two dimensional conductivity between a negative tab and a negative electrode.
