graphite: an ideal anode materials Natural graphite made of carbonaceous organic material under high temperature. It comes in two colors: black and steel grey with semi-metallicluster. This crystal structure is a hexagonal crystal system. This crystal structure is hexagonal and multilayered. It exhibits high heat conduction, temperature resistance and electrical conductivity. This includes lubrication, plasticity, corrosion and heat resistance.
Graphite, an older negative electrode material, is a good example. Comparable to other carbon materials its conductivity is higher and crystallinity is greater. Its good layered structure, charge-discharge potential and excellent layered structure make it a great negative electrode material.
Modifications: Enhance performance of anodematerials
Graphite electrodes with negative graphite use natural flake graphite. But there are some limitations.
(1) Flake graphite has a high specific area which is more effective in reducing the initial charge and the discharge efficiency of the positive electrode.
(2) Li+ is only able to be embedded at the edge of graphite, and then slowly diffuses into particles due to its layer structure. Flake graphite has an anisotropy that makes the Li+ diffusion path long and uneven. This causes a low specific ability.
(3) The graphite’s layer spacing is too small. This increases Li+’s diffusion resistance, but also makes it less efficient at delivering high rates of charge. Li+ forms lithium dendrites easily on graphite’s surface, leading to serious safety issues.
Natural graphite may be altered by techniques such as surface oxidation and surface fluorination. After taking into consideration cost, performance and other factors, industrial graphite modification uses a carbon coating process. A commercial application of modified graphite is capable of producing a specific amount of 340-370mA*h/g. The coulombic efficiency for the first week is 90%-93%. There’s also a DOD cycle time of over 1,000 times. This can meet most consumer electronic products. Specific requirements regarding battery performance.
Innovation: Tap the Potential of Graphite Applications
People are continuously pursuing new technology in lithium-ion batteries. This is due to the development of new vehicles and industries like 3C. This results in a greater graphite-anode requirement.
Graphite concentrate may be further processed in order to produce graphite products like graphene. This will allow graphite to be utilized in lithium battery applications at a higher level. One example is graphene, which has excellent conductivity, can help reduce volume expansion in electrode materials, greatly increasing the efficiency of power batteries. Graphene is used extensively in the lithium-ion’s negative and positive electrodes. Current collectors, separators, and conductive additives are all made from graphene. The market outlook for the future is very broad. This research area is currently at its center. Spherical graphite features good electrical conductivity. It can be used to replace negative electrode material in the manufacture of lithium-ion cells at home or abroad.
