Synthetic Graphite (Anode)
Synthetic (artificial) graphite anode powder engineered for lithium-ion batteries, offering higher purity and tunable particle morphology versus natural flake graphite. Distinct from general industrial graphite entries.
Overview
Synthetic graphite for battery anodes is produced by graphitising petroleum needle coke or coal-tar pitch precursors at temperatures above ~2500–3000°C, then milling, classifying and often coating particles to control SEI growth and first-cycle efficiency. Versus natural graphite, synthetic grades typically deliver higher purity, more isotropic particle shapes, better fast-charge behaviour and tighter lot control — at higher energy cost and CO2 intensity from the graphitisation step. Automotive cell makers blend synthetic and natural graphite or use coated spherical natural graphite depending on cost, energy density and charge-rate targets. China dominates both coke and graphitisation capacity; Western localisation programmes (EU, US IRA) are building alternative anode material plants. This record is specifically anode-grade synthetic graphite, not refractory or lubricant graphite.

Technical Specifications
Density
~2.2 g/cm³ (true density); electrode porosity lowers practical density
Tensile Strength
Not applicable as free powder; electrode composites depend on binder and calendaring
Temperature Resistance
Thermally stable well above cell operating range; SEI and electrolyte limit practical cell temperatures
Sustainability
Sustainability Rating
Graphitisation is electricity-intensive; grid carbon intensity dominates cradle-to-gate footprint. Recycled graphite from black mass is emerging but still limited versus virgin synthetic. Natural graphite mining has its own land-use and purification (HF) impacts — synthetic shifts burden to energy.
