Customer ServiceCompared with lamellar graphite, microcrystalline graphite has smaller grain size and higher disorder degree, and the particles are isotropic, so the lithium ion diffusion performance of microcrystalline graphite is higher in theory [ 4, 5 ]. It is an ideal raw material for anode materials for lithium-ion batteries.
Natural microcrystalline (figure 5 (a)) contains a large number of impurities between crystals and lamellae, mainly quartz (SiO 2 ), containing a small amount of magnesium oxide, calcium oxide and alumina.
The microcrystalline surface structure increases the contact area and bonding strength between the copper foil and graphite particles and reduces the contact angle between the copper foil surface and the electrolyte.
The changes of microstructure and electrical properties before and after purification were compared, and the lithium storage mechanism was analyzed, which provides a new idea for the deep processing of microcrystalline graphite, and provides some reference for broadening the application field of microcrystalline graphite. 2.
In the microcrystalline graphite concentrate purified by flotation, some impurities are impregnated in the graphite in the form of very fine particles, which cannot be completely dissociated, so only the most high-carbon products can be obtained. However, flotation process does not corrode the equipment and has a low cost.
In addition to improving the mechanical stability of the graphite electrode, the microcrystalline structure on the surface of copper foil can also increase the contact area between graphite particles and the copper foil, which will have a positive effect on the conductivity of the copper foil.
