Raw Material For Anode Materials

1. Core Product Positioning

Raw Material for Anode Materials is a dedicated graphite feedstock for lithium-ion battery anode materials. Using high-purity natural graphite or artificial graphite as the base material, it undergoes processes such as physical purification and particle size classification. Endowed with excellent lithium storage capacity and electronic conductivity, it acts as a core basic raw material for producing high-performance anode materials (e.g., natural graphite anodes, artificial graphite composite anodes) and is suitable for multiple anode production scenarios, including consumer electronics, power batteries, and energy storage batteries.                                                                                                                                                                                                                                                                                                                                                                                                                                                       

2. Core Product Features

High Purity & Low Impurities: Fixed carbon content ≥99.9% (for natural graphite) or ≥99.95% (for artificial graphite); total content of harmful impurities (Fe, Si, S, Na, K) ≤500ppm, preventing impurity ions from affecting battery cycle stability and safety.

Optimized Layered Structure: Retains the natural hexagonal crystal system layered structure of graphite (d002 interplanar spacing: 0.335-0.336nm) with moderate interlayer bonding force, facilitating lithium ion intercalation/deintercalation. The integrity of the layered structure is ≥90%, enhancing lithium storage efficiency.

Controllable Particle Size Distribution: Narrow particle size distribution (D10/D50/D90 deviation ≤15%) is achieved through classification technology. Customized particle size specifications of D50=5-20μm (for natural graphite) or D50=8-25μm (for artificial graphite) can be provided according to anode formulation requirements.

Low Specific Surface Area & High Tapped Density: BET specific surface area ≤15m²/g (avoiding excessive electrolyte consumption); tapped density ≥1.0g/cm³ (for natural graphite) and ≥1.2g/cm³ (for artificial graphite), which is conducive to improving the compaction density of the anode.

Excellent Chemical Stability: No chemical reaction with electrolyte within the voltage range of 0-5V; resistant to acid and alkali corrosion (no obvious dissolution in pH 4-10 environment), ensuring long-term battery cycle life.

 

 

3. Main Application Scenarios

Consumer Electronics Anodes: Raw Material for Anode Materials is applied for preparing anode materials in small lithium-ion batteries used in smartphones, laptops, smart wearables, and other consumer electronics. Thanks to its high specific capacity (≥360mAh/g), it meets the battery life requirements of such devices.​

Power Battery Anodes: Adapted for anode production of new energy vehicle (EV/PHEV) power batteries. With excellent cycle stability (capacity retention rate ≥85% after 1000 cycles) and rate performance (discharge capacity ≥90% at 1C rate), it is suitable for high-power charge-discharge scenarios.

Energy Storage Battery Anodes: Applied to anodes of energy storage system batteries (e.g., household energy storage, grid energy storage). It meets long-duration energy storage needs with low self-discharge rate (monthly self-discharge ≤3%) and cost advantages.

Special Anode Materials: Serves as the base raw material for composite anodes (e.g., graphite-silicon composite, graphite-hard carbon composite). It enhances the comprehensive performance of anodes through synergy with other lithium storage materials.
