Product Overview
Hard carbon is a non-graphitizable carbon material typically produced by pyrolyzing specially structured cross-linked resins at approximately 1000°C. Common types include resin carbon, polymer-derived carbon, and carbon black. It has gained significant attention as a promising anode material for sodium-ion batteries.
