Key Features & Advantages

Niobium Lattice Modification: Surface-functionalized with 1,396 ppm of Niobium (Nb) coating, providing an outstanding protective shield that dampens transition metal leaching at high voltage states.
Single-Crystal Mechanical Toughness: Unlike poly-crystalline variants, our single-crystal layout features an elite D50 of 3.507 μm, radically reducing internal gas evolution and phase cracking.
Minimized Phase Impedance: Suppressed surface alkaline trace elements (LiOH 0.242%) guarantee highly stable slurry processing and eliminate unwanted gelation errors during electrode blade application.

APPLICATION SCOPE: High-energy-density positive electrode material optimized for pouch-cells, testing configurations, and advanced solid-state electrolyte boundary validations.

PACKAGING: Securely packaged in industrial hermetic containers layered with specialized inner PE moisture shields, inclusive of authorized batch inspection data charts.

IMPORTANT NOTICE: Due to the rich Ni content (83%wt), this powder exhibits prominent hygroscopic attributes. Material containers should remain sealed until immediate transition into an anhydrous, inert glovebox setting to actively address how to prevent nmc moisture degradation before sintering steps.

Frequently Asked Technical Questions

Why is ATOMFAIR® 206 mAh/g NMC 811 Cathode Powder preferred for high-voltage testing?

ATOMFAIR® 206 mAh/g NMC 811 Cathode Powder utilizes an advanced single-crystal configuration that prevents micro-cracking and maintains structural integrity. This allows a robust discharge capability of 206.12 mAh/g when undergoing rigorous cycling windows.

What benefits does the Niobium (Nb) coating offer to this material matrix?

The integration of a dedicated 1396 ppm Niobium surface layer creates an effective chemical passivation wall. This layer suppresses side reactions with electrolytes and limits early voltage degradation at the particle boundary interface.

How does this single crystal nmc811 material behave during slurry processing?

By maintaining low residual alkali parameters (Li2CO3 at 0.131 %wt and LiOH at 0.242 %wt), the slurry pH is safely pinned at 11.36. This reduces unwanted viscosity spikes and gelation failures during casting.

What is the specific grain sizing distribution for this cathode powder batch?

The single-crystal architecture presents a clean, narrow granularity window featuring a precise D50 center at 3.507 μm and a controlled Dmax limit of 11.501 μm, enabling exceptional coating distribution density.

How to prevent nmc moisture degradation effectively in a laboratory environment?

To comprehensively solve how to prevent nmc moisture degradation, this high-nickel material must be preserved in hermetically sealed industrial barriers and unsealed strictly under ultra-dry environments or Ar-filled gloveboxes before electrode preparation.
