Intercalation Curves from Half Cell. We have reported earlier Li ion intercalation curves for graphite and ROHG carbon [17] (Figure 2).
Because the capacity reduction brought about by the half cell could be relieved by applying conductive belts, half cells combined with sixteen 200 [micro]m thick wires could achieve the maximum profit and could save 75% of the finger wet weight.
The lateral half cell should always be placed at remote earth, a distance from the pipeline that varies with the current flowing to a coating fault and the soil resistivity.

On addition of the gum arabica to the half cells the stability and voltage increased.
A good estimate of the "close" pipe to reference electrode potential can be made from a distant half cell by eliminating IR drop and other errors.
Phenol solution was placed in the anodic half and was used as reference half cell. The rest of the phenols were used as cathodic half.
These potentials are recorded at the same location every two months, with the half cell placed at the same spot.
Each of the half cell of which is made of a cubical container of high density polyethylene joined to the other through epoxy resin.
