Finishing electrode

Removal of the solvent was carried out by exposure of intermediate products of electrodes at the temperature 130-150°C within 30 - 40 minutes. Then the intermediate products were rolled for giving the required density to the electrode layer finished electrodes were cut from the obtained tape by means of the cliche. 

The bases for the hydrogen electrodes were of platinum foil they were platinized in a 2% solution of chloroplatinic acid in 1M HC1. The plating solution contained no lead. The finished electrodes were stored in water and rinsed with pure NMA just before being placed in the cells. 

Store the finished electrode (see Note 9) or proceed directly to Section 3.4. 

The application of the binder is important, since it determines the quality of the finished electrode, e.g., its surface uniformity (presence or absence of cracks, chipping, fractures, craters, lines, and rings) before pressing, its flexibility, its surface roughness, and the ability to bind the collector with the active material. Battery performance is the final index to check the binder usage. 

Figure 13 Design of recycling electrochemical detector. (A) Top view of finished electrodes on Pyrex and SiO. (B) Cross-section of assembled detector. Arrows indicate flow path. The following dimensions were used channel depth = 5-10 pm, channel width = 85 pm, electrode width = 50 pm (see top view, section A), electrode and channel length = 2-6 mm. A SCE reference electrode is placed in the flow outlet.

In individual cases, a balance between the utilization of the existing EDM capacity, the cost of producing finishing electrodes, and the time required for superfinishing has to be found. 

The glass frit type of thick film gold paste that has jnst been described is commonly used for electronic devices and sensors. The particle size of the gold powder is 3 xm or less, and particles will tend to be spherical in shape in order to achieve a dense film after firing. The finished electrode thickness after printing will usnaUy range from 1 to 20 pm, depending on particle size, metal content of the paste, etc.
