The specific performance of graphite as an electrode
Among lithium-ion battery materials, the anode material is the key to determining battery performance. As a graphite material with high crystallinity, the particle size of flake graphite directly affects the ratio of electrode specific surface area and edge carbon atoms, which has a great influence on the irreversible specific capacity during the first charge. Therefore, flake graphite plays a vital role in the battery.
First of all, flake graphite can reduce the amount of flake graphite powder in lithium batteries, greatly reducing the cost of the battery. Secondly, flake graphite has many advantages such as high electronic conductivity, large lithium ion diffusion coefficient, high embedding capacity and low embedding potential, so flake graphite is one of the most important materials for lithium batteries. Finally, flake graphite can stabilize the voltage of the lithium battery, reduce the internal resistance in the lithium battery, can make the battery storage time longer and increase the battery utilization time.
 
The performance of flake graphite in centrifugal pump
Centrifugal pumps are commonly used mechanical equipment in industrial production. Centrifugal pumps are used to transport acid and alkali corrosive liquids during use, so ordinary materials cannot meet the requirements of centrifugal pumps. Flake graphite has excellent characteristics such as good corrosion resistance and high temperature resistance, so flake graphite is the main material of centrifugal pumps.
The turbine box, front cover, shaft sleeve, impeller and other parts of the graphite centrifugal pump that are in contact with the conveyed liquid are made of flake graphite, because flake graphite powder itself has the characteristics of high temperature resistance and corrosion resistance, and its chemical properties are stable . The impeller in the graphite centrifugal pump is the main component. In order to increase its strength and toughness, asbestos and glass fiber are added to the original flake graphite.
