Synthetic Graphite Anode Production Line

Solution Overview

Synthetic graphite is the mainstream anode material for lithium-ion batteries, accounting for over 80% of the market. It features high electrical conductivity, excellent cycling stability, and favorable cost controllability, making it widely adopted in power batteries, energy storage batteries, and consumer electronics batteries. Its production line converts carbonaceous raw materials such as petroleum coke and needle coke into highly graphitized powder with a well-ordered layered structure through a series of specialized processes.
