Key Features & Advantages

Industry-Leading Coulombic Utilization: Outstanding initial cycle efficiency ceilings exceeding 97% dramatically limit active ion traps during early conditioning phases.
Superb Fast-Charge Transport: High electrical-network integration preserves capacities above 77 mAh/g even under rapid 5C charging routing profiles.
Strict Metal Purity Control: Total single magnetic/metal interferences are compressed below 1 ppm, eliminating parasitic short-circuiting risks inside wound architectures.
Predictable Rheological Dispersion: Fine submicron particle widths (D50: 1.5–2.5 µm) ensure outstanding slurry homogenization and smooth mechanical sheet casting.

APPLICATION SCOPE: High-performance polyanionic sodium-ion battery half/full cell configurations, ultra-safe stationary grids, and fast-charging device testing matrices.

PACKAGING & EXPIRATION: Vacuum hermetically sealed inside high-barrier industrial aluminum-plastic bags (200g packs or 1000g commercial bulk tons). Preserves uncompromised baseline characteristics for 12 months under dark, sealed conditions.

IMPORTANT NOTICE: Sulfate polyanionic networks carry acute environmental humidity sensitivities. Workpieces must be stored under 45°C, kept strictly below 70%RH storage settings, and processed instantly post-opening within dry gas glovebox environments to satisfy how to handle moisture sensitive sodium battery materials rules.
