Electronegativity is a constant. What changes when a second, third, ... bond is formed is the relative dipole orientations between the bonds due to changes in geometry and the net dipole moment of the molecule.

I was reading something today and they were talking about testing a half-cell battery. If we use lithium ion batteries as an example, looking at a graphite anode how would this cell be configured? I'm not sure how a battery can operate in this "half-cell" mode. Doesn't the battery need to be balanced? I suppose the source of lithium could be the electrolyte. Thanks for your help!
