Abstract
The traditional method of pressing CF, screen and SVO sheet assembly results in an electrode that is cupped and not flat. This results in the reduction of the effective volumetric energy density of the electrode or the addition of a process step of flattening of the cathode if at all possible. The new method of assembly effectively eliminates the cupping behavior and produces a flat electrode. In addition, the physical density of the cathode is also increased.
