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.

Perfect for Adding Privacy to a Piano Studio
Size: 2 Panel 8FT W, Size: 2 Panel 8FT W
I Ordered the 2 Panel version which is way too big for my needs... that's on me. So keep in mind that the picture shows a fabric made for two panels only being used on one and hence it is not pulled tight; it would pull tight and not be so wrinkly if it was set up properly as two panels. The metal pools that make up the panels seem to be well made, stable, and of good quality. They were very easy to put together and they stand up tall with plenty of height. The appearance of it with the fabric on it isn't as elegant as it could be, but it still looks good enough. The material is plenty solid, not allowing light through it, and thereby making a solid barrier. I am using it to block the view out the studio door when a student is sitting at the piano to avoid distractions from the hallway. It will allow a student to enter the studio with our distracting the student who is at the piano.

Room Divider That Gives Instant “This Is a Separate Space Now” Energy
Size: 3 Panel 12FT W
The Siebwin 3 Panel Folding Privacy Screen is surprisingly effective at changing the feel of a room without requiring construction, commitment, or somebody yelling about load bearing walls. The 12 foot width gives a substantial amount of coverage, making it useful for creating privacy, dividing open areas, blocking visual clutter, or setting up temporary sections within larger rooms. This saved us a ton of time and money in our new studio and enabled us to create a kitchen and office in one room. The wider feet make a huge difference because flimsy room dividers that collapse every time someone exhales too aggressively are deeply annoying. This one feels more stable and grounded once positioned. The folding design makes it easy to move around or adjust depending on the space, and it folds down relatively compactly when not in use. It is basically the introvert curtain wall of dreams. The material has a clean, neutral look that blends well into different room styles without screaming “temporary office cubicle panic.” It works well for apartments, studios, shared spaces, dressing areas, or simply hiding the mountain of chaos you swear you are going to organize tomorrow. Practical, portable, and refreshingly easy to use without turning setup into a three hour emotional event.

It's 2 panels holding 1 big privacy screen. Can't use as 2 separate 4' panels, but works great.
Size: 2 Panel 8FT W
This 2 panel privacy screen works well. Assembly was very straight forward, with easily labeled tubes. My son and I had it together in about 10 minutes, which was probably 3 minutes of me telling him to quit playing around and hand me the parts. It feels very sturdy, not likely to fall over or anything. The material fits well, with the Velcro being very strong. Measurements are all very accurate, with all pieces attaching properly. We have a similar privacy screen at work that we have to try and stretch out because the top and bottom Velcro doesn't fit quite right... this model does not have any issues though. The material is thin and light weight, but solid black so that you can't see anything through or behind it. I definitely think it's a great deal for the money. What I think would have given it 5 stars though, is if you had 2 totally separate 4' panels instead of 2 panels with one big screen. It really wouldn't cost any extra to make it so that the screen was in 2 pieces and you could use it as 2 separate panels instead of having to use it as one big panel. It says 2 panel folding privacy screens, but it's really one big one that folds in the middle.
