Carbon Electrodes

Advancing power and energy device technology
Our nonwovens, featuring carbon fibre networks, offer high C-rate capability when coated, and are produced using proprietary wet-laid technology to ensure high surface area and porosity. These carbon veils can be used as electrodes or current collectors in flow battery systems, significantly increasing the surface area for electrochemical reactions and enhancing electrical transfer kinetics.

Key Properties

High Electrical Conductivity

Our veils consist of highly porous interconnected conductive framework that facilitate the efficient flow of electrons during charge and discharge cycles.

High Ionic Conductivity

A porous conductive structure allows for the efficient movement of ions within the electrode.

Chemical Stability

The inherent corrosion resistance of the fibre resists degradation and maintains performance over many charge and discharge cycles.

Mechanical Stability

The structure of the nonwoven is designed to withstand the physical stresses of expansion and contraction during battery operation without degradation.

High Energy Density

Our electrode materials enable the storage of a large amount of energy in a small volume or mass.

Compatibility with Electrolyte

Materials can be selected to aid compatibility, ensuring that the electrode materials do not react adversely with the electrolyte.
