Critical element
Germanium (Ge)
Germanium can improve sulfide solid electrolyte performance and semiconductor behavior, but its strategic supply profile makes substitution important.
Supply signal
High concern: germanium availability and concentration can make Ge-rich materials hard to commercialize at scale.
Affected applications
- LGPS-family solid electrolytes
- Infrared and semiconductor materials
- High-value functional ceramics
Patent note
Germanium-rich electrolyte work should include a substitution map and claim strategy around lower-Ge or Ge-free variants.
