Abstract
A solid state electrolyte material including a decontaminated lithium conducting ceramic oxide material including a decontaminated surface thickness. The decontaminated surface thickness is less than or equal to 5 nm. The decontaminated surface thickness may be greater than or equal to 1 nm. The decontaminated lithium conducting ceramic oxide material may be selected from the group consisting of Li7La3Zr2O12 (LLZO), Li5La3Ta2O12 (LLTO), Li6La2CaTa2O12 (LLCTO), Li6La2ANb2O12 (A is Ca or Sr), Li1+xAlxGe2-x(PO4)3 (LAGP), Li14Al0.4(Ge2-xTix)1.6(PO4)3 (LAGTP), perovskite Li3xLa2/3-xTiO3 (LLTO), Li0.8La0.6Zr2(PO4)3 (LLZP), Li1+xTi2-xAlx(PO4)3 (LTAP), Li1+x+yTi2-xAlxSiy(PO4)3-y (LTASP), LiTixZr2-x(PO4)3 (LTZP), Li2Nd3TeSbO12 and mixtures thereof.
