Product Overview
This high-purity graphite sheet is engineered specifically to meet the rigorous physical and electrochemical demands of advanced battery research and next-generation electrode manufacturing. Refined to an exceptional 99.99% carbon purity level, this material provides an ultra-clean conductive substrate that minimizes background chemical interference, stabilizes interfacial charge transfer, and delivers uniform current distribution across active electrode surfaces.
Designed for versatile integration into experimental and production workflows, the substrate is widely utilized in lithium-ion, sodium-ion, solid-state battery R&D, and supercapacitor development. Beyond electrochemical energy storage, its structural integrity, high thermal resistance, and exceptional chemical inertness make it an essential solution for high-temperature semiconductor processing, metallurgy, and precision laboratory testing systems.
Every production batch undergoes stringent quality control to guarantee dense, defect-free microstructures and flat, uniform surfaces. With an extensive range of standard dimensions and fully customizable dimensional options, this synthetic carbon substrate offers the consistency, electrical reliability, and structural resilience necessary for demanding scientific experiments and scalable industrial processes.
Key Features
- Ultra-High 99.99% Carbon Purity: Extremely low trace ash and metallic impurity levels prevent parasitic electrochemical side reactions, ensuring reproducible experimental data during long-term battery cycling tests.
- Superior Electrical and Thermal Conductivity: Dense, anisotropic crystalline graphite alignment facilitates rapid electron transport and efficient planar heat dissipation under high-rate charge/discharge conditions.
- Comprehensive Standard and Custom Dimensions: Available across dozens of standardized thicknesses and surface footprints—from ultra-thin 1 mm research plates to robust 50 mm blocks—with custom cut-to-size specifications available on request.
- Exceptional Chemical and Corrosion Resistance: Highly resistant to harsh acidic, alkaline, and non-aqueous organic battery electrolytes, preventing substrate degradation across broad voltage windows.
- High-Temperature Structural Stability: Retains mechanical rigidity, dimensional stability, and inert surface characteristics in inert or reducing atmospheres at elevated operational temperatures.
- Precision Surface Machining: Engineered with flat, smooth, and parallel contact planes to provide uniform contact pressure, low interfacial resistance, and seamless adhesion during active material slurry coating.
- Protective Research Packaging: Packaged securely in 5-piece sealed packs to prevent surface oxidation, dust accumulation, and physical transit damage prior to cleanroom or glovebox deployment.
