abstract = {We developed a new atomistic method to model
(non-equilibrium) redox reaction using empirical force
fields for use in MD simulations. To this end, we added the
(formal) ionisation state as a discrete variable into the
“split charge equilibration” method (SQE). This
extension allows atoms to swap integer charges across bonds,
in addition to exchanging fractional charges. We call this
method “redoxSQE”, and, in first steps, used it to study
contact electrification and to set up a model rechargeable
nano-battery that reproduces the generic features of the
discharge of a macroscopic battery qualitatively. Other
popular charge-transfer force fields fundamentallycannot
describe any history-dependent effect because they calculate
the charge distribution as a unique function of atomic
positions. For similar reasons, state-of-the-art DFT-based
methods fail to describe redox reactions in
non-equilibrium.},
