Microcrystalline Graphite

This product is made from carefully selected high-quality natural microcrystalline graphite minerals and is a high-performance precursor material specifically developed for the preparation of graphene and novel carbon materials. Unlike traditional battery-grade graphite anode materials, this product fully utilizes the inherently small crystallographic characteristics of microcrystalline graphite, aiming to provide a cost-effective and highly efficient raw material option for the large-scale preparation of graphene.

Graphite crystal particle size: 1-2 μm

Characteristics: Microcrystalline graphite itself is formed by the random stacking of micron-sized graphite grains. The particle size distribution of this product is strictly controlled within 1-2 μm, meaning it does not require energy-intensive mechanical grinding and pulverization; its original particle size already meets the "sheet-like" threshold for graphene preparation.

Microstructure: Clusters, formed by the stacking of fine grains.

Application: Graphene precursor (non-anode material).

 Core Advantages: Why is it a superior graphene raw material?

High Reactivity and Easy Exfoliation: Microcrystalline graphite consists of extremely fine grains, resulting in a larger specific surface area and more abundant edge and defect sites compared to large-particle flake graphite. This makes it easier for reactants to penetrate and intercalate during chemical oxidation or electrochemical intercalation, leading to higher oxidation and exfoliation efficiency and reducing the cost of graphene preparation.

No Grinding Required, Native Particle Size: Preparing graphene from ordinary flake graphite often requires ultra-fine grinding, which easily introduces impurities and damages the crystal structure. The 1-2μm native particle size of this product directly meets the feed requirements for graphene preparation, maintaining crystal integrity.

Unique Product Characteristics: Graphene prepared from microcrystalline graphite typically has a smaller sheet size (less than 1 micrometer) and more edge active sites. This small-sized graphene has unique application advantages in conductive inks, coatings, high-efficiency adsorbents, and the reinforcement and toughening of composite materials.

Application Guide

Special Note

This product is a graphene-specific material and is not recommended for direct use as a negative electrode material in lithium-ion batteries. Although microcrystalline graphite can be used as a negative electrode after modification (such as surface coating, granulation, etc.), the original design logic of this product is to use it as a "raw material" to prepare thinner graphene, not as a "finished product" for lithium intercalation. Its 1-2μm particle size, without secondary granulation modification, may lead to significant irreversible capacity loss and poor cycle stability when used directly as a negative electrode.
