2023-06-27With the acceleration of electronic product updates and the increasing demand for miniaturization, high integration, and high function electronic equipment heat dissipation management, a new electronic product heat dissipation technology - graphite data heat dissipation new solution has also been launched. This solution is based on graphite sheets, which are a new natural graphite solution that uses graphite sheets with high heat dissipation efficiency, small space occupation, light weight, and uniform bidirectional heat conduction, Eliminate "hot spots", shield heat sources and components, and improve the functions of Consumer electronics. This new type of graphite sheet is used for laptops, flat panel displays, digital cameras, mobile phones, and Personal Care Assistant.The battery specific graphite sheet is made of expanded graphite by pressing and roasting. The battery specific graphite sheet has high temperature resistance, thermal conductivity, flexibility, elasticity, and good

Without reducing the cost of raw materials, even if the electrical performance of Graphene is no better, battery manufacturers can not afford to consume hundreds of thousands of dollars per ton.2. Process issuesThe technical problems caused by the sheet structure of Graphene for batteries are mainly the preparation of electrode paste. The electrode paste requires good fluidity, dispersibility and proper viscosity. The dispersion of Graphene sheets in the electrode paste is a problem, especially the electrode paste cannot be dispersed by adding dispersants. Graphene has a large surface area, which has a great impact on the stability of the slurry settlement, cannot guarantee the consistency of each batch, and affects the battery performance.3. Other factorsThe lamellar structure of Graphene for batteries inhibits the di
2023-06-271. Anode materialDue to its unique two-dimensional structure, excellent electronic transmission capacity and large specific surface area, Graphene for batteries has great potential to replace graphite as a new generation of negative electrode material for lithium ion batteries. The lithium storage mechanism of Graphene is similar to other carbon materials. When charging, lithium ions are separated from the positive electrode and embedded in the carbon material layer, forming Li2C6. When discharging, lithium ions are separated and returned to the positive electrode. Due to the special two-dimensional structure of Graphene, When the lamellar spacing is greater than 0.7 nm, both sides of Graphene can store lithium ions. At the same time, due to the existence of wrinkles, Graphene can also store lithium. In theory, its capacity may be twice that of graphite, higher than 744 mAh/g.In addition, Graphene is mostly micro nano sized, much smaller than bulk graphite, which makes the diffusion p
2023-06-26The application fields of high-purity graphite include metallurgy, military, light industry, electrical battery industry, and fertilizer. Can it be called high-purity graphite? In order to make more people familiar with it, here are some related knowledge points about high-purity graphite for everyone? I hope you can bring some better help when choosing in the future.High purity graphite is widely used in fields such as metallurgy, machinery, environmental protection, chemical industry, electronics, medicine, military industry, and aerospace. It has high purity and high strength graphite properties. In fact, the existence of graphite flakes now makes graphite have excellent lubricity. Generally speaking, the larger the ordinary graphite flakes, the better their lubricity. When we use it, we need everyone to know that the graphite industry technology is still at a relatively low level in the world, and the products are mainly raw materials and initial processing products. Therefore, th
2023-06-26High purity graphite is widely used in various industries, so its use is definitely very extensive. In fact, this high-purity graphite mainly means that the carbon content of graphite is more than 99.99%. It is also widely used in advanced refractory materials and coatings in metallurgical industry, stabilizers for military initiating explosive devices, pencil lead in light industry, carbon brushes in electrical industry, electrodes in battery industry, catalyst additives in fertilizer industry, etc. Of course, the scale crystals of the product are complete, thin and tough, with excellent physical and chemical properties. It has good thermal conductivity, temperature resistance, self-lubrication, conductivity, thermal shock resistance, corrosion resistance, and other properties. In addition, the high-purity graphite (also known as flake high thermal conductivity carbon powder) mentioned today has high strength. Of course, in addition to this, it also has advantages such as good therma
