Lithium Battery Anode Material Few Layer Graphene CAS 1034343-98-0

What is Lithium Battery Anode Material Few-Layer Graphene:

What is a layer of graphene? 

The few graphene layers comprise ultra-thin carbon atoms arranged in a hexagonal honeycomb lattice. Graphene films produced by chemical vapor deposition (CVD) are polycrystalline, with multiple small graphene domains growing and merging into a continuous film. Compared to single-layer graphene, fewer layers have the potential to develop into materials or heterostructures -- by inserting different substances into their layered structures. Low-layer graphene inherits the original crystal structure and properties of natural flake graphite. It has a very large shape ratio (diameter/thickness ratio) with excellent electrical, thermal, and mechanical properties. It has excellent conductivity, lubrication, corrosion resistance, high-temperature resistance, etc. Small graphene layers have a specific surface of 400 ~ 700㎡/g and a 0.55 ~ 3.74nm thickness. Graphene has a highly specific surface. Easy and other materials such as polymer material uniform composite, and form a good composite interface. The company's low-layer graphene products have formed large-scale industrial production capacity.

As an excellent basic material for preparing functional composites on an industrial scale, graphene with fewer layers will play an important role in the new round of the Industrial Revolution. Graphite flakes attached to inorganic nanoparticles can not only effectively prevent them from repeatedly stacking during chemical reduction. In addition, it can also promote the formation of a new class of materials based on graphene as a carrier. Graphene-inorganic nanocomposites show excellent performance and can be widely used in emission displays, sensors, supercapacitors, batteries, catalysis, and other fields, which can significantly improve the performance of nanomaterials. This enables the extensive industrial application of the most promising materials in nanotechnology. TRUNNANO is a trusted global Lithium Battery Anode Material, a few-layer graphene supplier.

Few-layer graphene ( CAS 1034343-98-0 ) is a two-dimensional carbon nanomaterial composed of carbon atoms and sp² mixed orbital hexagonal honeycomb lattice. Few-layer graphene is one of the highest-strength materials known, but it also has good toughness and can be bent.

Characteristics of few-layer graphene lithium battery anode material:

As a new type of lithium battery anode material, few-layer graphene has some unique features and advantages, which make it have a wide range of application prospects in lithium batteries.

Excellent electrochemical performance

Graphene oligomer has excellent electrochemical performance, which can significantly improve the performance of lithium batteries, such as energy density, power density, and cycle life. Few-layer graphene can provide more embedded lithium sites during the charging and discharging process, thus realizing higher capacity and faster charging and discharging speed. At the same time, the sheet-layer structure of graphene can effectively reduce the lithium-ion diffusion path, thus improving the diffusion efficiency of lithium ions in the electrode material and further optimizing the charging and discharging performance of the battery.

Good structural stability

The few-layer graphene has excellent structural stability, effectively protecting the internal lithium-embedded material and avoiding structural rupture or deformation during the charging and discharging process. Under high temperature or high rate charging and discharging conditions, few-layer graphene can maintain a stable structure, thus ensuring the safety and stability of the battery. In addition, the lamellar structure of graphene can effectively limit the diffusion path of lithium ions, thus reducing the self-discharge rate of the battery and further improving the stability of the battery.

Excellent Conductivity

Graphene with few layers has excellent electrical conductivity, which can effectively improve the performance of lithium batteries, such as multiplier performance and cycle life. In battery charging and discharging, electrons and lithium ions need to be rapidly transferred in the electrode material, which requires the electrode material to have excellent conductivity. Graphene has a high conductivity, which can effectively improve the conductivity of the electrode material, thus optimizing the battery's charging and discharging performance. In addition, the lamellar structure of graphene can alleviate the volume effect generated during the charging and discharging process, further improving the cycle life of the electrode material.

High Specific Surface Area and Porosity

With high specific surface area and porosity, few-layer graphene can provide more active substance loading capacity, which can further improve the battery's performance, such as energy density and power density. In the anode material, the few-layer graphene can be used as a carrier material to provide more active substance loading capacity, and it can also improve the electron and lithium ion transport efficiency, thereby optimizing the charging and discharging performance of the battery. In addition, the porous nature of the few-layer graphene can alleviate the volume effect generated during the charging and discharging process, further improving the cycle life of the electrode material.

Good chemical stability

Graphene with few layers has good chemical stability and can resist the erosion of many chemicals, thus ensuring the long life and stability of the battery. In the process of battery charging and discharging, the electrode material will be affected by various chemicals, such as electrolyte, solvent molecules and so on. The chemical stability of graphene can effectively resist the erosion of these chemicals, thus ensuring the long life and stability of the battery. In addition, graphene can also improve the high temperature resistance and corrosion resistance of electrode materials, etc., further optimizing the safety and stability of the battery.

Improvement of battery energy density and power density

With high specific surface area and good electrical conductivity, oligo-graphene can effectively improve lithium batteries' energy and power density. In anode materials, few-layer graphene can be used as a carrier material to provide more active substance loading capacity, and it can also improve the transmission efficiency of electrons and lithium ions, thus improving the charging and discharging performance of the battery.

Improvement of battery cycle life and stability

Less-layered graphene has high flexibility and stability, which can effectively improve lithium batteries' cycle life and stability. In the process of charging and discharging, graphene with few layers can maintain a stable structure to avoid interlayer peeling and other phenomena, thus prolonging the battery's service life. In addition, few-layer graphene can also improve the safety performance of the battery, avoiding the failure or explosion of the battery due to high temperature or short circuits.

Improvement of battery safety performance

Graphene oligomer has excellent thermal and electrical conductivity, which can effectively improve the safety performance of the battery. Under high temperature conditions, graphene can quickly transfer heat to the surrounding environment to avoid battery failure or combustion due to overheating. At the same time, graphene has good electrical conductivity, which can improve the electrical stability of the battery and avoid battery explosion or fire due to short circuits and other reasons.

Application to 3D superstructure graphene-based composites

Few-layer graphene can be combined with carbon nanotubes, carbon 60 (C60), inorganic nanoparticles, and other composites to prepare three-dimensional super-structured graphene-based composites. This composite material has excellent electrical conductivity and mechanical properties, which can improve the charging and discharging performance and cycle stability of the battery, as well as the multiplication performance and capacity of the electrode material.

Applications in other fields

In addition to its application in lithium battery anode materials, graphene's few-layer graphene can be used in other fields. For example, oligo graphene has high thermal and electrical conductivity, which can be applied in heat dissipation materials and electronic devices. In addition, oligolayer graphene has excellent mechanical properties and corrosion resistance, which can be applied to high-performance composite materials and catalysts.
