A Zero That Wandered

Re-referencing a semester of LiCl–KCl voltammetry against each scan's own lithium onset

A research poster from the School of Emergent Priorities re-references 186 cyclic voltammograms recorded over one semester against a teaching laboratory's shared Ag/AgCl reference in a LiCl–KCl eutectic cell, using the lithium deposition onset in each scan. The reference drifted in three steps of +18, +14 and +8 mV, each in the week of a logged intervention on the cell, and re-referencing narrows the spread of nine lab groups' median peak potentials from 52 mV to 11 mV.
