Abstract

See full text

A solid-state battery comprises an anode in electrical contact with an anode current collector, including a first ionically conductive solid electrolyte material having a susceptibility to reduction in a presence of lithium metal such that, upon contact with lithium, the ionically conductive material partially reduces to a mixed ionic and electronic conductor including a partially reduced species, a cathode, and a separator positioned between and in ionic contact with the anode and cathode. The separator is formed of a second ionically conductive solid electrolyte material which is in contact with the first ionically conductive material but not susceptible to reduction in a presence of lithium metal and not soluble for the partially reduced species such that the separator has a susceptibility for migration of lithium ions from the mixed ionic and electronic conductor and impedes propagation or exchange of the partially reduced species from the mixed ionic and electronic conductor.
