graphite: an ideal anode materials Natural graphite made of carbonaceous material organic origin under high temperatures It is a mixture of steel gray and black grey with semi-metallicluster. The hexagonal crystal system is the crystal structure. It features a hexagonal layered structure with high temperature resistance, heat conductivity and heat conduction. , Lubrication and plasticity.
Graphite is an older negative electrode material. Graphite is a more desirable negative electrode material than carbon materials. Its conductivity, crystallinity, and good layered structure are all better than those of other carbon materials.
Modifications: Optimize anode material performance
Graphite Negative Electrodes generally use natural flake graphite. But there are a few drawbacks.
(1) Flake graphite has a large surface area which has a greater influence on the first charge of the negative electrode and its discharge efficiency.
(2) The graphite layer structure determines that Li+ can only penetrate the material’s end and slowly diffuse into the particles. 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+ is easy for graphite to form lithium dendrites and deposit it on the graphite’s surface. This can pose serious safety hazards.
Natural graphite can be modified to address these issues using technologies such as surface oxidation and surface fluorination. After taking into account cost and performance, industrial graphite modification is dominated by carbon coating. Modified natural graphite is a commercially available material with a specific capacity between 340 and370 mA*h/g. This has a coulombic efficiency in excess of 93% in the first week. The DOD cycle time of over 1,000 times can also be used to supply small electronic products. Specific requirements for battery performance.
Innovation: Tap the Potential of Graphite Applications
People are continuously aiming to improve the performance of lithium-ion battery technology, with a focus on higher energy density, longer life, and high power density. This results in a higher graphite-anode requirement.
Graphite concentrate is able to be further processed to make graphite products. These include graphene (spheroidized graphite), flexible graphite (fluorinated graphite), nuclear graphite or silicon-impregnated graphite), flexible graphite (spheroidized graphite), expandable graphite (spheroidized graphite), fluorinated graphite and nuclear graphite. This will allow graphite to be used in lithium batteries at a higher level. Graphene is a good conductor and can help reduce volume expansion in electrode materials. This will greatly increase the power batteries’ performance. Graphene is widely used as a positive electrode, negative electrode, current collector, separator, and conductive additive in lithium-ion cells. Future market opportunities are very broad, so it is the center of current research. Spherical graphite features good electrical conductivity and high crystallinity. It can be used to replace negative electrode materials in the production of lithium-ion cells at home and abroad.
