摘要
A rechargeable battery has a battery cell at least partially enclosed by a casing. The battery cell comprises (1) a substrate; (2) a cathode and cathode current collector on the substrate, the cathode being electrically coupled to the cathode current collector; (3) an electrolyte electrically coupled to the cathode or cathode current collector; and (4) a permeable anode current collector having a first surface electrically coupled to the electrolyte and an opposing second surface, the permeable anode current collector: (1) having a thickness that is less than about 1000 Å and that is sufficiently small to allow cathode material to permeate therethrough to form an anode on the opposing second surface of the permeable anode current collector when the battery cell is electrically charged, and (2) that is absent an overlayer on the opposing second surface of the anode current collector. Positive and negative terminals are electrically connected to the battery cell. The permeable anode current collector may be a grid with perforations.
