About this material
Tantalum-doped LLZO is the air-stable counterweight to the sulfides: a dense cubic garnet pellet with 0.3–0.8 mS/cm conductivity that can be handled, polished and characterised without a glove box. Relative density matters more than conductivity here — porosity at the grain boundaries dominates the measured resistance.
Pellets are supplied sintered and dimensionally checked. Polish both faces before use, apply a thin lithium or Au interlayer, and expect to need 1–5 MPa of stack pressure during cycling to maintain contact as lithium strips and plates.
Documentation, controls and care
Quality controls
- Certificate of analysis per batch
- Moisture by Karl Fischer, reported per lot
- Trace metal screening
- Retained samples held for 12 months
Handling & storage
- Store sealed under dry air or argon, away from light and ignition sources.
- Hygroscopic — dispense into a septum vial rather than reopening the stock bottle.
- Wear nitrile gloves, eye protection and a lab coat; consult the SDS before handling.
