A method of manufacturing a zinc-manganese dioxide cell includes applying a first electrical conductor to an electrically non-conductive substrate and applying a second electrical conductor to the electrically non-conductive substrate. The method further includes applying a layer-shaped negative electrode directly to the first electrical conductor, applying a layer-shaped positive electrode directly to the second electrical conductor, providing a layer-shaped separator, applying at least one electrolyte layer to the layer-shaped negative electrode and/or to the layer-shaped positive electrode and/or to the layer-shaped separator, and forming a stack of layers with the sequence negative electrode/separator/positive electrode. The negative electrode is prepared of a paste comprising zinc powder (mercury free), electrode binder, and solvent and/or dispersant. The positive electrode is prepared of a paste comprising manganese dioxide, conductivity agent for improving electrical conductivity, electrode binder, and solvent and/or dispersant.

The invention relates to a battery comprising at least a cathode current collector, a cathode, a separator, an electrolyte, an anode and an anode current collector, the cathode being disposed between the cathode current collector and the separator, and the anode being disposed between the separator and the anode current collector, the battery further comprising a sealing gasket disposed on the periphery of the cathode, of the anode and of the separator and connecting the inner peripheral edge of the cathode current collector to the inner peripheral edge of the anode current collector. Said sealing gasket is at least partly made of a viscoelastic elastomeric material.

A solid-state lithium battery cell comprises a support, and a plurality of electrodes on the support, the electrodes comprising a cathode and an anode. An electrolyte lying between the cathode and anode comprises an oxygen-rich electrolyte layer. In another version, a multilayer electrolyte comprises an oxygen-rich electrolyte layer and an oxygen-deficient electrolyte layer.

A stretchable battery and the method of manufacturing the same. The stretchable battery can be manufactured by using a printing process. The construction of the stretchable battery can comprise a first layer of an elastomer film, a first current collector layer, a layer of cathode, a separating layer, a layer of anode, and a second current collector layer. Metal traces can be used to couple with the first and/or the second current collector layers.
