It’s been years since my last time heard about Graphene battery which can solve my trouble in charging my phone once a day.
But soon nothing anymore. So I search and find the progress online.
Graphene is currently the thinnest but hardest nanomaterial in the world; it is almost completely transparent, absorbing only 2.3% of light; currently the world’s smallest resistivity material: because its resistivity is extremely low, the electrons run very fast. Therefore, it is expected to be used to develop a new generation of electronic components or transistors that are thinner and faster in conduction; since graphene is essentially a transparent, good conductor, it is also suitable for manufacturing transparent touch screens, light panels, and even It is a solar cell. .
Graphene is a new type of material with strong electrical and thermal conductivity and strength. It can make plastics have good conductivity by incorporating one percent of graphene into plastics. One thousandth of graphene can be added. Improve the heat resistance of plastics by 30 degrees Celsius; if added to the battery, the storage speed will increase by a lot.

Super capacitor

Since graphene has an extremely high surface area to mass ratio, graphene can be used for the conductive electrode of a supercapacitor. Scientists believe that this supercapacitor will have a higher stored energy density than existing capacitors.

Studies have shown that graphene filters may outperform other desalination technologies.

Due to its modified chemical function, large contact area, atomic thickness and molecular gate structure, graphene is an excellent choice for bacterial detection and diagnostic devices.
What can Graphite do

1. Refractory materials include refractory bricks, catastrophic, continuous casting powder, mold core, mold detergent and high temperature resistant materials.

2. Steelmaking: Graphite and other impurity materials can be used as recarburizers in the steelmaking industry. Carburizing uses a wide range of carbonaceous materials, including artificial graphite, petroleum coke, metallurgical coke and natural graphite. Graphite for steelmaking carbonizers is still one of the main uses of earthy graphite in the world.

3. Conductive materials: Graphite is widely used in the electrical industry as electrodes, brushes, carbon rods, carbon tubes, anodes for mercury rectifiers, graphite gaskets, telephone parts, coatings for television tubes, and so on.

4, for wear and lubrication materials: graphite is often used as a lubricant in the machinery industry. Lubricating oils are often not used under high-speed, high-temperature, high-pressure conditions, while graphite wear-resistant materials can work without a lubricant at temperatures between 200 ° C and 2000 ° C and at high sliding speeds (loom / s).

5, as corrosion-resistant materials: graphite has good chemical stability. Specially processed graphite, which has the characteristics of corrosion resistance, good thermal conductivity and low permeability, is widely used in the manufacture of heat exchangers.

6, for anti-scale and anti-rust materials: graphite can prevent boiler fouling. Tests have shown that adding a certain amount of graphite powder to water can prevent scaling on the boiler surface. In addition, graphite can be used for corrosion protection and rust prevention on metal chimneys, roofs, bridges and pipes.
