Provided is a stacked electrode assembly including: a lowermost electrode arranged on a lowermost portion of the stacked electrode assembly; an uppermost electrode arranged on an uppermost portion of the stacked electrode assembly; at least one unit stacked body arranged between the lowermost electrode and the uppermost electrode and including a positive electrode, a negative electrode, and a separator, the separator being arranged between the positive electrode and the negative electrode; and a separator arranged between the lowermost electrode and the at least one unit stacked body, and between the at least one unit stacked body and the uppermost electrode. A capacity and energy density of a lithium battery may be improved by employing an electrode including a mesh electrode current collector as the lowermost electrode or the uppermost electrode of the stacked electrode assembly.

An lead-acid battery is described. The battery includes a carbon fiber electrode having a paste containing a novel additive including one or more carbons, organic expanders, and barium sulfate.

A battery cell includes A anode electrodes each including an anode active material layer arranged on an anode current collector, C cathode electrodes each including a cathode active material layer arranged on a cathode current collector, and S separators, where A, C, and S are integers greater than one. At least one of the anode current collector and the cathode current collector includes a composite current collector including a fibrous membrane coated with a conductive material.

A method for production of an electrode for a battery cell of an electrical energy storage device by a generator includes spraying an electrode powder onto a metallic substrate web by a spraying device of the generator and compressing the electrode powder onto the metallic substrate web by a stamping device of the generator. Before the spraying, the electrode powder is electrically charged by corona or tribological charging.
