Graphite Felt Anode Flow Battery Electrode Enhanced Porosity China Manufacturer Premium Grade
Product Description
PAN Based Graphite Felt 3MM Thickness for Vanadium Redox Flow Battery/ Other Kinds of Batteries
Flexible Graphite Soft Felt is a dedicated graphite felt electrode material for flow batteries, manufactured through customized processing technologies to meet the specific performance requirements of different flow battery types. Its core production processes include non-woven needle punching, carbonization, graphitization, and fiber surface post-treatment. Featuring uniform thickness, flat (felt structure), and consistent electrochemical performance across the entire material, it has been widely applied in vanadium redox flow batteries, zinc-bromine flow batteries, and zinc-air (zinc-oxygen) flow batteries.
Specification
Preparation process
(1) PAN-based pre-oxidized fibers( Carbon Fiber) are woven and processed on high-end non-woven needle punching equipment to produce flat felt with specific thickness requirements, square meter weight, and good uniformity as raw material.
(2) Catalyst coating: At the entrance of the continuous carbon graphite furnace, the industrial flat felt of the oxide filament is first uniformly coated with sintered catalyst using specific equipment.
(3) High temperature sintering: The flat felt is continuously fed into a continuous carbon graphite furnace, where it undergoes carbonization, deposition, and graphitization treatment to obtain an intermediate product of graphite felt with a large amount of carbon nanotubes deposited on its surface.
(4) Surface treatment: The intermediate product of graphite carbon fiber is continuously introduced into the activation furnace, and the intermediate product of graphite carbon fiber with a large number of carbon nanotubes deposited on the surface is subjected to carbonylation treatment to increase the electrochemical activity of the electrode graphite felt.
