Abstract (en)
[origin: WO2015181508A1] The invention concerns a lead-acid electrochemical battery comprising a negative electrode and a positive electrode (2), in which the negative electrode comprises: a current collector formed from a carbon sheet having a thickness of between 50 μm and 200 μm; first and second layers made from lead respectively covering the first and second faces of the carbon sheet; and first and second layers of an active material containing lead, having a thickness of between 100 μm and 500 μm, and disposed on either side of the carbon sheet, respectively on the first and second layers made from lead; and in which the positive electrode (2) comprises: a current collector formed from a titanium sheet (20) having a thickness of between 50 μm and 250 μm; - first and second layers made from electrically conductive metal oxide (21 a, 21 b), respectively covering the first and second faces (20a, 20b) of the titanium sheet; and first and second layers of an active material containing lead (22a, 22b), having a thickness of between 100 μm and 500 μm, disposed on either side of the titanium sheet, respectively on the first and second layers made from metal oxide (21 a, 21 b).
