Graphene and Yixinfeng jointly explosive nanomaterial disperser: Driving the future of new energy vehicles
In the era of rapid progress in new energy vehicles, lithium-ion batteries, as their core power source, directly determine the cruising range, safety and overall competitiveness of new energy vehicles through their performance. As a rechargeable secondary battery, lithium-ion batteries are widely used in fields such as electronic information, electric vehicles, and smart grids due to their characteristics of high specific energy, high working voltage, long cycle life, and small size.
Ⅰ.Dilemmas of anode materials for lithium-ion batteries
As a key component of lithium-ion batteries for new energy vehicles, anode materials play a decisive role in the capacity, power, safety and stability of batteries. Currently, although many high-capacity anode materials such as metallic lithium, alloy materials, silicon-based materials, tin-based materials, lithium titanate and transition metal oxides have a theoretical specific capacity of more than 1000 mA·h/g, they are facing many thorny problems.
1.The Problem of Lithium Dendrites：During charging, the uneven deposition of lithium ions on the surface of the anode forms lithium dendrites, which can cause problems such as effective lithium loss, increased internal resistance, capacity attenuation, destruction of the SEI film, diaphragm puncture, and internal short circuit, seriously affecting the performance and safety of the battery.
2.The Challenge of Volume Variation：High-capacity anode materials experience significant volume changes during the process of lithium insertion and extraction. For example, the volume change of silicon-based materials can reach 300%, and that of tin-based materials can reach 260%. The drastic volume change can lead to the pulverization, shedding, and cracking of the anode materials, damage the structural integrity and electronic conductivity, impair the stability of the SEI film, and accelerate the aging and degradation of the battery.
3.Bottlenecks in electron and ion transport：High-capacity anode materials usually have poor electron and ion transport properties, leading to polarization losses during the charge transfer process and reducing the power density and cycle efficiency of the battery. The mismatch or incoordination of electron and ion transport will also cause the uneven distribution and deposition of lithium ions on the anode surface, further exacerbating problems such as lithium dendrites and volume changes.
Ⅱ.The Advantages of Graphene in the New Energy Field
Graphene, a two-dimensional nanomaterial in which single-layer carbon atoms are arranged in a honeycomb structure through sp2 hybrid orbitals, has extraordinary mechanical, optical, and chemical properties. In the aspect of anode materials for lithium-ion batteries in new energy vehicles, graphene exhibits remarkable advantages.
1.Conductive Additive or Coating：As a conductive additive or coating, graphene can effectively improve the electron transport performance of anode materials, inhibit the formation of lithium dendrites, and enhance the stability of the SEI film.
2.Porous or Hollow Structure：When used as an anode material in a porous or hollow structure, graphene utilizes its high specific surface area and porosity to improve the storage and transport capabilities of lithium ions and alleviate the volume change of the anode material.
3.Composite or Coating Structure：Forming a uniform and tight composite or coating structure with other high-capacity anode materials, graphene can significantly improve the comprehensive performance of the anode material.
4.Interface Engineering Carrier：With its high specific surface area and active functional groups, graphene, as a carrier of interface engineering or modification technology, can introduce different ionic additives or coatings to optimize the interface reaction and transport process between the anode material and the electrolyte.
Ⅲ.The Advantages of the Yixinfeng Heli Blasting Nanomaterial Disperser in the Aspect of Graphene
The Yixinfeng Heli Blasting Nanomaterial Disperser has brought new opportunities for the preparation and application of graphene.

Compared with traditional equipment, it saves 70% of energy and doubles the efficiency. Under normal pressure and room temperature, without chemical addition, 3 - 5 micron graphite particles are directly exfoliated to prepare single-layer graphene through physical stripping, achieving clean operation. The intrinsic single-layer graphene prepared by the physical method is free of oxidation and chemical addition, completely retaining the functional characteristics of graphene.

3.Optimizing the Performance of Graphene: When the graphene prepared by this physical exfoliation method is compounded with other anode materials, with the excellent dispersion performance of the Yixinfeng Heli Blasting Nanomaterial Disperser, it can combine more evenly, laying a solid foundation for improving the performance of lithium-ion batteries in new energy vehicles.
Ⅳ.The Yixinfeng Heli Explosive Nanomaterial Disperser Contributes to the Development of the New Energy Automobile Industry
The new energy automobile lithium-ion battery has extremely high requirements for the energy conservation and environmental protection of anode materials. Graphene, as a new type of carbon material, with its characteristics of low cost and high performance, has great potential as a new anode material.
