Patent ID: 8530074

Claim:
A rechargeable battery comprising at least first and second series-connected cells which are located one above the other in a stack, the first cell and the second cell each have a positive electrode, a negative electrode and an electrolyte located between the positive and negative electrodes wherein a common core passes through the stack and a first connecting line from the positive electrode of the first cell passes adjacent the common core and a second connecting line from the negative electrode of the first cell passes through the common core while a first connecting line from the positive electrode of the second cell passes through the common core and a second connecting line from the negative electrode of the second cell passes adjacent the common core thereby producing reverse polarities of the first and second connecting lines which pass through the common core so that an electromagnetic coupling of the second connecting line from the first cell is inductive, that is, opposite to an electromagnetic coupling of the second connecting line of the second cell with respect to a magnetic flux direction in the common core.
