Product Description

Product Description

Graphite Felt for Flow Battery Electrodes:PAN Based Graphite Fiber Fel

A must-have for Flow Batteries, and its role cannot be underestimated. It can provide a reaction interface for the redox reaction of the electrolyte solution, allowing the performance of the flow battery to be even better.
Our Graphite Fiber Felts are made from pre-oxygenated silk fibers through a series of proprietary processes:
Pre-oxidation-Short-cutting-Felt-making-Carbonization-Graphitization-Activation
Its carbon content is over 99.9%, which is higher than carbon felt. Under non-oxidizing atmosphere conditions, its working temperature could be over 2000 °C.
Features :
1, Very flat felt body, Uniform thickness
2, Good chemical stability, Super Acid-resisting and Oxidation Resistance
3, Consistent electrochemical performance throughout,which can increase the speed of electrochemical reactions.
4, High specific surface area/effective electrochemical surface area, ensuring full contact between the electrode and the electrolyte and improving the utilization rate of the electrolyte.
5,Electronic filtration permeability
6,Superior Electrical Conductivity, which can reduce the internal resistance of the battery and minimize electrochemical polarization during charging and discharging.
