Key Features & Advantages

Homogeneous Material Purity: Features an uncompromised structural configuration with highly uniform elemental distribution across the matrix.
Enhanced Operational Efficiency: Specifically engineered to demonstrate superior electrochemical performance, significantly boosting transfer kinetics at targeted bands.
Optimized Sintering/Microstructure: Advanced synthesis allows for lower required operating temperatures and ideal grain boundary integration during cell fabrication.

APPLICATION SCOPE: Lithium-ion battery, sodium-ion battery, and related electrochemical cell validation applications.

PACKAGING: 8μm thickness × 280mm width, 50 meters per roll container package specification.

IMPORTANT NOTICE: This product is highly sensitive to ambient exposure. Keep containers tightly sealed or handle exclusively within an anhydrous inert gas environment to prevent phase contamination or degradation before thermal validation. Ambient environment conditions must remain strictly at temperature ≤ 25°C and humidity ≤ 65%, avoiding direct sunlight and chemical corrosion.
