(57) [Summary] (Modified) [PROBLEMS] At least one electrode formed by applying a slurry in which an active material, a conductive additive and a binder are dispersed and mixed in a solvent to a porous current collector foil and contacting the slurry. The present invention relates to an electrochemical cell having one. It is particularly important that the active slurry does not move through the holes of the current collector. A barrier is positioned on the opposite side of the current collector to block holes while the current collector is coated with the slurry. After evaporating the solvent, the second different active material is slurried, powdered, Apply to the opposite side of the current collector as pellets or sheets. As an example of this cathode, SVO / current collector / CF There are X configurations. The active material on the opposite side of the current collector may have the same chemical composition. |
