A battery can include a separator, a first current collector, a protective layer, and a first electrode. The first current collector and the protective layer can be disposed on one side of the separator. The first electrode can be disposed on an opposite side of the separator as the first current collector and the protective layer. Subjecting the battery to an activation process can cause metal to be extracted from the first electrode and deposited between the first current collector and the protective layer. The metal can be deposited to at least form a second electrode between the first current collector and the protective layer.
