Product Overview

 

Graphene/porous carbon composite powder is a composite material powder composed of graphene and porous carbon, with a sandwich structure and high porosity. This structure enables composite materials to have a larger specific surface area and superior performance. Its unique properties have wide applications in sodium ion batteries. Sodium ion battery is a type of secondary battery (rechargeable battery), which mainly relies on the movement of sodium ions between the positive and negative electrodes to achieve the charging and discharging process. Sodium ion batteries include a positive electrode, a negative electrode, an electrolyte, a separator, and a current collector. The structure and performance of the positive and negative electrode materials determine the sodium storage performance of the entire battery. The positive and negative electrodes are separated by a diaphragm to prevent short circuits, the electrolyte serves as a medium for ion circulation, and the current collector plays a role in collecting and transmitting electrons. The positive and negative electrode materials of sodium ion batteries can accommodate more sodium ions, thus possessing high capacity storage capacity and able to withstand a large number of charge and discharge cycles, making them more suitable for long-term use and high-intensity application scenarios.


Technical Parameter

Appearance:Black powder

 

Product Features

 

Conductivity: Graphene, as a two-dimensional material, has excellent conductivity, and the addition of porous carbon further enhances the conductivity of the composite material.

Thermal conductivity: Graphene has excellent thermal conductivity, and when combined with porous carbon, the overall thermal conductivity of the material is also improved.

Mechanical properties: Graphene has strong mechanical properties, providing excellent strength and toughness for composite materials.

Adsorption capacity: Porous carbon has a rich pore structure, which enables composite materials to have a large specific surface area and excellent adsorption capacity.


Application Fields

 

In the field of energy, graphene/porous carbon composite powder can be used as electrode material to improve the energy density and power density of energy storage devices such as sodium ion batteries and supercapacitors.

Catalytic field: As a catalyst carrier or catalyst itself, graphene/porous carbon composite powder can provide abundant active sites to promote chemical reactions.

Environmental field: Utilizing its high adsorption capacity, it can be applied in fields such as water treatment and air purification to remove harmful substances.

In other fields such as biomedicine, sensors, and electronic devices, graphene/porous carbon composite powders also have potential application value.

This one's in color
Format: Paperback
This book was glorious. It presented the invasion vividly. The Allied forces sure kicked Rommel's butt, and although the American forces had many casualties, the Germans were defeated. After the Allies liberated France, people revealed hidden Tri-Color French flags. I was interested to learn about the problem of French hedgerows and how an American sargent (Curtis Cullin) improvised a brush-cutter out of the beach barricades in order to leave the tanks less vulnerable as they crossed the fields. Thank you Curtis! The book also talked about a German tank commander named Michael Wittmann and his Tiger tank. This was a powerful weapon that destroyed a group of Shermans very quickly and then took out part of a convoy. The allies finished him off by using British Fireflies (a British type of tank) that sent a disabling shot into the tank. Michael Wittman and his crew escaped. There was good tank action in this book. It feels like you're stuck in the middle of battle, but you're safe. But you're watching in horror. The drawings of the Avro Lancasters were really great. That's my favorite British plane. The air war made the difference in the invasion's success. If it weren't for the RAF and the Allied air forces, the invasion might not have succeeded. I'm eleven years old, and this is a really good book. I learned a lot. This book had really good maps, and it was in color. That helped me a lot. The blood was not too bloody -- just scribbles. Parent note: my son says blood and guts included.

Great read for a WWII enthusiast
Format: Paperback
Purchased for my nephew who is 11 and a WWII aficionado, "Bombing Nazi Germany" and "Normandy" did not disappoint. While I got him the graphic novels because he is a visual kid, he really enjoyed the text. Which is good because there is a lot of text. I am an avid reader of graphic novels and found these books to be more text-driven than much of what I've read. That said, the prose is solid, unadorned, and moves the narrative smoothly from pane to pane. I recommend this for anyone fascinated by war histories who also values detailed illustrations of the same.

I wish my Dad had lived long enough to have this given to him!
Format: Paperback
As I said for Mr. Vansant's Gettysburg graphic novel, this is perhaps the best visual description of all of the planning, logistics, and follow-up battles that gave the Allies their second front, and began the march to Berlin, and the eventual downfall of Hitler's Thousand Year Plan. I have studied War History for as long as I can remember - focusing mostly of the American Civil War, World War 2, and Vietnam; three of the United States' greatest turning points in warfare - but my Dad and I shared a huge interest in WW2, watching as many documentaries on it as we could. What most people do not know about the importance of the war is that it is one of the few times that most of the world was not only involved either directly or indirectly, but also it is one that everyone - and I mean everyone, from the footsoldiers, leaders, and civilians - knew exactly why and what they were fighting for. While it seems odd to refer to events so brutal as noble, that is the best way to describe World War 2, since most of the world was involved in it, and why.

10-year-old grandson loves this book
Format: Paperback
I bought this for my grandson who is very interested in World War II. He has just turned 10. He loves the book. It seems to be the perfect balance between text and pictures. He will learn about the experiences of his great grandparents while learning to read at the same time.

Thought it did a really good job framing the big picture, as well as showing some of the nitty gritty details of the fighting that took place. Even though I thought I already knew a lot about D-Day, I still learned some things along the way. Note: although I do most of my reading on my Kindle Paperwhite, I read this on my iPad Kindle app instead. I don't expect the graphics to come off too well on a non-tablet Kindle so did not even download it there.
