Coworkers of the Laboratory for Materials Electrochemistry, in cooperation with colleagues from Weierstrass Institute, Berlin, constructed a new theoretical model that successfully explains the operation of a modern insertion battery. The crucial novelty is that the electrochemical coupling between the numerous active particles constituting a modern electrode is taken into account. When such a coupling occurs between particles with non-monotone potential profile (most battery materials), many unusual phenomena may occur such as a zero-current voltage hysteresis during charge/discharge, non-continuous (cascade-like) charging of particles or multiple potential equilibria within a single electrode. All these predicted model-phenomena have been experimentally verified. The new model is based on the principles known from classical thermodynamics and holds equally for storage devices as different as supercapacitors, hydrogen storage particles and, last but not least, ordinary rubber balloons connected via a common vessel.
