Forschung zur Anwendung von Graphenpolymeren-Lithium-Ionen-Batterieausrüstung

Graphene is a graphite thin tablet composed of a layer of carbon atom. It is the most well -known material in conductive performance, which makes it great in the field of microelectronics. The theoretical research of graphene has a history of more than 60 years. In addition to the application of electronic devices, graphene has been widely used in the fields of battery electrode materials, hydrogen storage materials, nano -composite materials, and biosensions. Polyineine has the characteristics of chemical nature, large surface area, good electrical conductivity, simple preparation, and high stability, so it has been widely used in batteries, sensors, anticorrosive protection and other fields. However, due to the problem of decreased the activity of the pH value of the solution with the pH value of the solution, the application scope was greatly constrained. This article studies the preparation, development and prospects of graphene polymers.(Lithium - Ion Battery Equipment)

1. Graphery

1.1 Glamine oxide

Galdhamne is a new type of carbon material with excellent performance and has a high -scale and surface -rich functional group. The composite mix of oxide graphene includes polymer composite materials and inorganic composite materials. It has a wide range of application areas.

1.2 Preparation of graphene oxide

The oxidation method of graphite is to treat graphite with inorganic strong proton acid, insert the small molecules between the strong acids into the graphite layer, and then oxidize it with a strong oxidant KMNO4.

1.3 Application prospects for gallery oxide

Similar to a single carbon nanotuba (SWCNT), graphene has excellent performance such as heat, force, electricity. However, polymer molecules are not easy to enter the surface of the SWCNT, and the huge ratio of graphene oxide -oxide is given excellent composite performance. After modification and restoration Graphene tablets have greater potential in changing the mechanics, flow, permeability, and degradation stability of the polymer matrix. In addition, due to the low cost of oxide graphene and easy raw materials, it is more competitive than SWCNT. At present, the relevant patent reports of gown glycene/polymer composite materials abroad have covered the field of fuel cells in the energy industry, and hydrogen storage materials for the energy industry, the microre catalyst carrier of the chemical industry, conductive plastic, conductive coatings, and fire prevention of the construction industry Flame retardant materials and other aspects.

2. Polyine

2.1 Functional polyiline

Since the 1970s, the research of conductive polymer has developed greatly. Polybira, polybine, and polyiline have now become the three most watched electrical polymer varieties. In particular, polyiline, its synthetic raw materials are easy to obtain and simple synthetic method, and the cost is far lower than polyphenolic and polypya. Become one of the most studied and most applied conductive polymers [2]. At present, people change their properties by introducing-SO3H, -COOH and other functional groups in the polyiline chain to form functional polyiline.

2.2 Polybenzene sulfonic acid

The existence of -SO3H groups have greatly improved the solubility, environmental stability, and thermal stability of polyiline in the aquatic solution and most organic solvents. Within the pH range of 1 to 12, the sulfonine polyiline can still maintain its electricity Chemical activity, and the negative power of the-SO3H group can fix the substance with positive electrical electricity, and at the same time exclude the interference of negative electrical substances, and is used to have a faster response speed for chemical modification electrons.

3. The composite of grapne and polyiline

3.1 The interaction of graphene and self -doped polyiline

Flexible graphene (GS)/Paniline (PANI) nano -fiber composite material is synthesized by a simple and fast two -step method. (PSS-GS) and the PANI nano-fiber vacuum filtration of the PANI nano-fiber is prepared to prepare the PSS-GS/Pani nano-nanofiber suspension. Through the field, scanning electron microscope (Fe-SEM) and high-resolution transmission electron microscope (HR-TEM) observation can clearly see a typical highly ordered laminar PSS-GS/PANI composite material, and polyiline nano Fiber is covered by PSS-GS. In addition to the advantages of thinness and flexibility, because of the good combination of GS and high-capacity PANI fingertips, the prepared PSS-GS/PANI composite film thin film is more than pure PSS-GS. Good electrochemical performance.
