Engineering highly non-linear charging schedules has implications in formation and cell aging. If it is possible to selectively omit (or emphasize) the intercalation or phase transition at select potentials, this markes a new "engineering lever" to pull, allowing to alter the growth of the SEI only electrochemically and not diffusive as for instance done in Cicvaric et al. and Garcia et al. for metal electrodes. Expressed differently: Applying a nontrivial non-linear voltage or current signal onto a battery creates the opportunity to intentionally activate or mitigate some corrosion mechanisms. Since the resulting graphs as Figure allow the correlation to mechanisms in the anode/cathode at different c-rates it becomes possible to construct Pourbaix-like diagrams of potential ranges to avoid. This diagram could then directly contribute to the engineering of both electrochemical processes and engineering of the SEI composition during formation and use.
