Multi Layer Graphene

Overview

Multilayer Graphene Conductive Additive (C) Powder is a high-purity graphene material consisting of stacked graphene sheets with excellent electrical conductivity, high specific surface area, and mechanical robustness. In electrochemical systems, multilayer graphene functions as a conductive network former, enhancing electron transport pathways within electrodes and reducing internal resistance during charge–discharge cycling.

Unlike conventional carbon additives, multilayer graphene forms interconnected percolation networks at lower loading levels, enabling improved electrochemical utilisation of active materials while maintaining structural stability.
