2023-06-27The special graphite for batteries has good chemical stability, and the specially treated graphite has the characteristics of corrosion resistance, good thermal conductivity, and low permeability, so it is widely used to make heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, and pumps, and is widely used in petrochemical, hydrometallurgy, acid-base production, Synthetic fiber, paper making and other industrial sectors, Can save a large amount of metal materials.It is a material for casting, casting, pressing and high-temperature metallurgy. Because of its low coefficient of thermal expansion of graphite and its resistance to rapid cooling and heating, it can be used as a mold for glassware. After graphite is used, Ferrous can be used to obtain castings with accurate size, smooth surface and high yield, which can be used without machining or slightly processing, saving a lot of metal. In the powder metallurgy process of produc
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.

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
