An apparatus and process for applying an electrode paste onto a substrate for use in an electrolytic cell. The apparatus includes a mixing device which mixes, and then dispenses, predetermined amounts of an electrode paste and a polymerization initiator onto a substrate. The mixing device is constructed so as to substantially preclude polymerization of the electrode paste during such mixing, as well as to preclude polymerization prior to application of the mixture onto the substrate. |

DETAILED DESCRIPTION The present invention is directed to an apparatus for applying an electrode paste onto a substrate for use in an electrolytic cell.
The apparatus comprises means for releasably supporting an electrode paste and means for releasably retaining a polymerization initiator.
Means for mixing a predetermined amount of the electrode paste and polymerization initiator are also included.
The mixing means serve to mix, and then release, predetermined amounts of the electrode paste and polymerization initiator onto the substrate.
Additionally, means, operatively associated with the mixing means, are used for precluding polymerization of the electrode paste prior to actual release and application of the mixed polymerization initiator and electrode paste onto the substrate.
It is contemplated that, in a preferred embodiment, the polymerization preclusion means includes a static, or motionless, mixer.
In a preferred embodiment of the invention, the apparatus further comprises means for regulating a desired amount of electrode paste and polymerization initiator which is to be released from the mixing means and onto the substrate.
Regulating means may also be used for regulating the release of desired amounts of electrode paste and polymerization initiator into the mixing means.
Furthermore, means for curing (e.
g.
an oven) the electrode paste after it has been applied onto the substrate is likewise contemplated.
It is also contemplated that the curing occur in at least a two stage process.
For example, it may be desirous to only partially cure the electrode paste after it has been applied onto the substrate, and then to more fully cure it at a later stage.
Indeed, in one preferred embodiment of the present invention, an electrolyte is mixed with an electrolyte polymerization initiator in a similar fashion as discussed with respect to the electrode paste and polymerization initiator.
Inasmuch as an electrolyte typically adheres better to a soft, or partially cured electrode paste, such a multi-step curing of the electrode paste is desirable
