A solid amorphous electrolyte composition for a thin-film battery. The electrolyte composition includes a lithium phosphorus oxynitride material containing a sulfide ion dopant wherein the atomic ratio of sulfide ion to phosphorus ion (S/P) in the electrolyte ranges greater than 0 up to about 0.2. The composition is represented by the formula:where 2x+3y+2z=5+w, x ranges from about 3.2 to about 3.8, y ranges from about 0.13 to about 0.46, z ranges from greater than zero up to about 0.2, and w ranges from about 2.9 to about 3.3. Thin-film batteries containing the sulfide doped lithium oxynitride electrolyte are capable of delivering more power and energy than thin-film batteries containing electrolytes without sulfide doping.
