A lithium-ion battery having a wound electrode configuration includes a wound cell element that includes a positive electrode and a negative electrode, the positive electrode including a current collector and a first active material and the negative electrode including a current collector and a second active material. The second active material has a potential that is greater than 0.2 volts versus a lithium reference electrode. The wound cell element includes a region where an edge of the positive electrode is provided proximate an edge of the negative electrode and the second active material near the edge of the negative electrode does not extend beyond the first active material near the edge of the positive electrode.
