Battery and a method of manufacturing a battery
Abstract:
The printed battery has cathode and anode electrodes with terminals to connect to an external circuit, separator therebetween and electrolyte. An anode electrode material is applied on one side of the separator and a cathode electrode material on the opposite side. The anode material is dry and hydrophobic and is prepared by providing an anode active material, conductive material, solvent and a binder that are mixed to form an anode ink. The anode ink is applied on a substrate and then dried. In response to the drying, the solvent evaporates and the anode ink forms a film on the substrate. The prepared anode material is applied on the separator. An electrolyte solution is printed on the separator that has the anode material thereon. A cathode material is applied between a collector material and separator.
