Name: Ronbay SC92Y Single-Crystal Ni91 NCM Cathode
Material Type: Single-Crystal High-Energy-Density Lithium Nickel Cobalt Manganese Oxide (NCM)
Product Code: SC92Y
Brand: Ronbay
Product Introduction:
The Ronbay SC92Y is a single-crystal high-energy-density lithium nickel cobalt manganese oxide (NCM) cathode material with Ni / Co / Mn molar ratio of 91.35 / 6.45 / 2.20. The material is supplied as a black powder with D50 4.10 μm, tap density 1.80 g/cm³, and specific surface area 0.80 m²/g. SEM confirms single-crystal microstructure with spherical-type particle morphology, and XRD shows no impurity phase peaks. The SC92Y is broadly applicable to a wide range of cylindrical lithium-ion battery products.

Application Areas:
The Ronbay SC92Y is broadly applicable to a wide range of cylindrical lithium-ion battery products.
Packaging:
Vacuum-sealed in aluminum-laminated film bag, placed in plastic drums or cardboard boxes. Each drum contains 12.50 kg ± 0.02 kg net weight of material.
Shelf Life:
Under vacuum-sealed packaging, store in a cool, dry place. Shelf life: 1 year.
Handling, Storage & Protection:
Avoid impact and inversion during handling. Store in a clean environment at room temperature, cool and dry. Avoid sunlight, heat, and rain during transportation. Use the material immediately after opening the packaging bag; if not used immediately, reseal and store to prevent moisture absorption.
