Transcript – Refine Microstructure in Renewable Carbon Fiber for Energy Storage Application

This project is a test for Iran to protect its about how to use power, refinery waste and people poppy industry waste Colignan to replace the worry expensive precursor called natural for producing renewable carbon fiber, a low cost and also a better performance. While Negaunee has been long explored for using as a precursor for carbon fiber because of the high costs of the carbon fiber vacuum. How I want the performance is very limited. Most mechanical performance, electro conductive performance. We have been trying to explore both mechanical and electro conductive performance. You hope that ligne carbon fiber can also be used for battery material. In this study, we use different fractionation method to derive different type of ligne. We also use different feedstock from our Dr. Bill Rooney to develop a different type of lignin and using Lesa the worst type of ligne, we have manufactured a different type of carbon fiber, use a customized carbon fiber manufacturing facility using this facility. What we have shown is that we can manufacture as you to wear high quality carbon fiber material using these different carbon fiber material. We have established several findings. The first finding is that microstructure. We are the defense, the mechanical performance of LIGNE, carbon fiber as you can. So in FUGERE.

Are three that the more uniformed actually figure, if got a figure, one has some data that shows electoral contact and performance, but also are the number two point is electoral conduct and mechanical performance are highly correlated and both electoral contact and mechanical performance are correlated, are defined by the perfect microstructure, as you can see, figure to eat, it’s Malatia electro conductive performance.

If you’re going to a solution that the better you have, you can see different type of electro conductive performance. The finger to finger, one finger to be is showing the electro conductive performance and also tensile strength there coronating and then Fugere to be.

It also shows that electro conductivity is actually correlating with the crystal content and the crystal size to the crystal content to the crystal size, but it’s actually correlating with both of them. So the conclusion is that both electro conductive and mechanical performance are defined. Abida, are more crystal content and better crystal size and then feel to see your energy source using the low temperatures technology by Dr. Wu. How we can actually see the less amorphous structure that means tomorrow more you crystal structure, the less amorphous structure you have, the better the electrical activity is. So the figure from what we showed is that actually a different type of feedstock material also can generate ligne carbon fiber with different performance. But more importantly, it’s a solid discovery that we found the more uniform, the lignin, carbon fiber and the Allegheny is, the more uniform lignin structure is the better mechanical performance and eventually electro conductive performance we can’t achieve.

So what are we finding is that if you really want to have very good ligne carbon fiber, what you really need is worry, uniformally no matter how you want to generated it from the fractionation or generated from new feedstock. These are basically uniform ligne you can produce Lini.

Carbon fiber is a worry high Cristol conquered and larger size and that type of lignin, carbon fiber can have better electro conductive and mechanical performance and it can be used for different types of applications, including battery and including mechanical and different type of applications.

So that’s the conclusion of our project. We really appreciate the project support and this T-3 project has enabled us to compete for a lot of national funding and including we have landed a multi stream integrated biorefinery project from the Department of Energy and that these are two applications we recently published. And we also have some more publications. Thank you so much.
