Oxide Solid Electrolyte Powder

Name: Oxide Solid-State Electrolyte Series — LLZO & LATP for Lithium Batteries

Series Type: Oxide ceramic solid electrolytes (Garnet + NASICON)

Series Code: XN-OXIDE-SE

Description:

Xnergy’s Oxide Solid-State Electrolyte Series covers two leading oxide-class chemistries for next-generation all-solid-state lithium batteries (ASSLBs) — garnet-type LLZO and NASICON-type LATP. As oxide-class electrolytes, both materials offer unique advantages over sulfide and halide chemistries: air stability, broad electrochemical window, lithium-metal compatibility (LLZO), and low-cost raw materials. As a result, oxide electrolytes are the preferred choice for high-energy-density lithium-metal solid-state batteries, ceramic separator pellets, polymer-ceramic composite films, and safety-critical applications. Xnergy supplies battery-grade LLZO and LATP powders with high phase purity, industry-leading conductivity, and controllable particle sizes.

Application:

The series serves as solid electrolytes for all-solid-state lithium batteries, lithium-metal batteries, ceramic separator pellet sintering, polymer-ceramic composite electrolyte films, gel-polymer hybrid electrolyte fillers, and academic studies of garnet and NASICON-structure ion transport. Furthermore, the air-stable oxide chemistry simplifies handling for laboratory and pilot-scale production environments compared with sulfide electrolytes.

Series Overview:

Available particle size grades for the series: D₅₀ = 6 μm / 2 μm / 300 nm. Custom particle size and pack quantities available on request.

Characteristics:

Two complementary oxide chemistries

LLZO garnet offers higher conductivity (~2 mS/cm) and intrinsic lithium-metal compatibility for high-energy-density solid-state cells. LATP NASICON offers cost-effective conductivity (1 mS/cm) and excellent compatibility with composite polymer-ceramic films. Therefore, customers can choose the chemistry that best matches their cell architecture and performance targets.

Air-stable handling

Unlike sulfide electrolytes, oxide ceramics do not release toxic gases on ambient exposure. As a result, both LLZO and LATP can be handled in normal laboratory environments with significantly simpler safety requirements than sulfide chemistries.

High phase purity (99.9%)

Stringent quality control delivers reproducible target phase formation. Moreover, low impurity content prevents parasitic reactions and preserves ionic conductivity in finished cells.

Controllable particle size grades

Both products are available in multiple particle size grades (D₅₀ = 6 μm / 2 μm / 300 nm) to support varied processing routes — from traditional ceramic sintering (coarse) to nanocomposite films (sub-micron).

Wide electrochemical stability window

Oxide chemistries offer compatibility with high-voltage cathodes (NCM, LCO, high-nickel oxide systems) without LiNbO₃ interface coatings, simplifying cell architecture.
