Workshop
The first company in China to complete the development of carbon paper and composite carbon board chain.We focus on the research, development, production, sales and overall solutions of key carbon-graphite materials in the new energy fields
such as proton exchange membrane fuel cells, lithium ion batteries and
flow batteries, and take it as our responsibility to help the "double carbon" strategy.
The main products include carbon paper based on hydrogen fuel cell,
gas diffusion layer, composite graphite bipolar plate, conductive paste
based on lithium battery, electric heating film and silicon-carbon anode
material, etc., which have been mass-produced, and the product
performance and production capacity have reached the domestic
advanced level, and the market prospect can be expected.

Benchmarking Toray Japan: the cost is reduced by 40%, the air permeability is increased by 10%, and the amount of binder is significantly reduced.
In-situ growth of carbon nanofibers for reinforcement
Benchmarking the US DOE standard: the plate thickness is reduced from 1.0mm to 0.6mm, the strength is more than doubled, the accuracy is 10 microns, and the industrial chain is fully localized.
R&D design | content |
Gradient carbon-paper composite microporous layer technology | Usually, it is to improve the pore structure of the base layer, prevent the electrode catalytic layer from "flooding" and prevent the catalytic layer from leaking to the base layer during the preparation process. |
High uniformity dispersion technology of carbon brazing in papermaking | The fiber is well dispersed in water, which reduces the flocculation of pulp and increases the evenness of papermaking. |
Strengthening technology of carbon brazing dimension CVD | CVD process can minimize the amount of adhesive and greatly improve the flux and mechanical properties of diffusion layer. |
Improvement of micro-cracks in microporous layer | Reduce the diameter of water droplets and reduce the probability of GDL flooding blockage. |
Optimization of resin types | Several resins with excellent comprehensive properties were selected to improve the mechanical properties of bipolar plates. |
Resin modification | The resin was optimized by modification to improve the comprehensive properties of composite bipolar plate. |
Graphite modification technology | By modifying or treating the surface of graphite particles, graphite was modified to improve the performance of bipolar plate. |
