Battery materials
Solid-State Electrolytes
Solid electrolyte candidates compared by structural family, synthesis evidence, patent density, and deployment risk.
Audience
All-solid-state battery teams triaging garnet, sulfide, argyrodite, and sodium conductor options.
Why this matters
Conductivity alone does not decide solid electrolyte viability. The real screen needs synthesis, air stability, dendrite behavior, IP, and material availability signals.
Ranking basis
- Known lithium or sodium conducting structure family
- Synthesis evidence and practical processing route
- Patent density around the family
- Supply-risk and integration burden
Ranked candidates
Candidate Materials
These rows are curated as an indexable public screen. Each candidate links into the broader material profile when a profile exists.
| Candidate | Role | Stability | Synthesis | Patent Density | Supply Risk | Why It Matters |
|---|---|---|---|---|---|---|
| Li7La3Zr2O12 LLZO Material class | Oxide garnet electrolyte | Known garnet family | High-temperature ceramic route | High | Medium; lanthanum and zirconium exposure | Strong oxide stability benchmark with ceramic processing and interface challenges. Evidence: Garnet SSE literature and Lattice Graph profile data |
| Li6PS5Cl Chloride argyrodite Material class | Sulfide argyrodite electrolyte | Known argyrodite family | Mechanochemical and solid-state routes | High | Low to medium | A high-conductivity sulfide benchmark where IP and moisture handling dominate. Evidence: Argyrodite SSE literature and synthesis corpora |
| Li10GeP2S12 LGPS | High-conductivity sulfide benchmark | Known LGPS family | Solid-state routes | High | High; germanium exposure | Excellent conductivity anchor, but supply and patent constraints push substitution searches. Evidence: LGPS literature and patent corpus |
| Na3PS4 Sodium thiophosphate | Sodium solid electrolyte | Known sodium conductor family | Mechanochemical and heat-treatment routes | Medium | Low | A useful sodium-ion comparator when lithium supply or cost is the constraint. Evidence: Sodium SSE literature |
