Détails

This product is designed for researchers working with all-solid-state lithium batteries and advanced electrochemical systems, including lithium-sulfur, lithium-air, and lithium-water batteries. The LLZTO (tantalum-doped lithium lanthanum zirconium oxide) ion conductive ceramic sheet is a dense oxide solid electrolyte with a diameter of 12 ± 0.1 mm and a thickness of 1.0 ± 0.05 mm, offering an ionic conductivity exceeding 1 mS/cm at room temperature. Its stable crystalline phase (PDF#80-0457) ensures reliable performance under ambient conditions, and the sheet is compatible with CR2032-type coin cell assemblies. The material exhibits high hardness yet significant brittleness, requiring careful pressure control during cell assembly to avoid cracking. For electrochemical testing, the sheet can be polished, gold-sputtered on both sides, and subjected to EIS measurements. This product supports the evaluation of solid-state electrolytes in practical cell configurations, making it suitable for fundamental and applied battery research.

Suitable for CR2032 power cradle test

1. Size: The diameter of this electrolyte sheet is ±0.1mm, which does not affect the assembly of the buckle battery. The mold should be careful to use for users with high accuracy (for example, in fixed-size molds).

2. Process: This product is a ceramic piece, not a vegetative embryo made of pure powder pressing.

3. Stability: This product is stable to air moisture and can be used in conventional environments.

4. The electrolyte sheet has high hardness but high brittleness. Pay attention to the applied pressure and uniformity when using it. Comparatively test the assembly and buckle method. Do not roll the sheet. The lithium metal negative electrode is generally made of molten lithium or lithium sheets, and the contact surface with the electrolyte sheet is melted.

5. Test ionic conductivity: This product has been evenly polished, but it still needs to be simply polished before use. For millimeter-level thickness, you can use 2000 mesh sandpaper to polish it to the smooth surface. For 100 micron-level flocking gauze, you can use slightly polish it.Then spray gold on both sides to protect the side from spraying gold. Use a multimeter to test that the resistance between two points on the same side is between 1 and 10Ω, and the spray gold is successful.The electrolyte sheet with successfully sprayed gold was clamped on both sides with a buckle test clip and conducted an EIS test.

6. Assembled buckle battery: suitable for CR2032 model buckle battery case.The assembly structure is the same as that of conventional liquid buckles. The battery sealing pressure needs to be adjusted by itself, and it is only necessary to slowly press until the edge of the buckle shell is slightly arc-shaped, and the pressure used is smaller than that of conventional liquid buckles.(For reference only)

Oxide solid electrolyte sheets are stable in the air and are often used to assemble buckle batteries or other structural equipment.It is used in all-solid state lithium batteries, advanced lithium sulfur batteries, lithium air batteries, lithium water batteries, etc. [LLZTO Tantalum-Doped Lithium Lanthanum Zirconium Oxide Solid-State Electrolyte Sheet]
