abstract = {Batteries are pivotal components in overcoming some of
today's greatest technological challenges. Yet to date there
is no self-consistent atomistic description of a complete
battery. We take first steps toward modeling of a battery as
a whole microscopically. Our focus lies on phenomena
occurring at the electrode-electrolyte interface which are
not easily studied with other methods. We use the redox
split-charge equilibration (redoxSQE) method that assigns a
discrete ionization state to each atom. Along with
exchanging partial charges across bonds, atoms can swap
integer charges. With redoxSQE we study the discharge
behavior of a nano-battery, and demonstrate that this
reproduces the generic properties of a macroscopic battery
qualitatively. Examples are the dependence of the battery's
capacity on temperature and discharge rate, as well as
performance degradation upon recharge.},
