This manuscript explored linear, quasi-non-linear, and on linear charging of batteries. The motivation is first and foremost an interesting toy example where a battery is potentiodynamically charged in such a way that the current remains constant -yielding virtually the same dQ/dV plots. This example is further explored using classic linear sweep voltammetry to yield information-dense dQ/dV plots that contain the congruent shape of the non-linear current response. Superimposing a sinusoidal onto a linear sweep voltammogram of a battery is then shown to be able to yield spikes in the differential capacity plot whose physical manifestation in an experiment remains to be validated. Superimposing an arctan onto a linear sweep voltammogram enables to reduce the area at selected potentials in the dQ/dV plot but yields overshoots in the dQ/dV diagram at higher potentials. Superimposing an arctan onto a non-linear potentiodynamic schedule that would have produced a constant current response mitigates these overshoots and enables the selective omission of potential ranges in the differential capacity plot. After fully charging the simulated cell there is a minimum in Li-loss to the SEI that can be correlated with phase transitions occurring in the cathode, in the chosen example NMC811, that are mitigated. The presented study is an entirely simulative endeavor and remains to be experimentally validated in future research.
