Stable lithium storage capacity and strong adaptability<\/b><\/strong><\/p>\nIt has a hexagonal crystal lattice layered structure, which\u00a0interlayer gap is\u00a00.335nm,\u00a0perfectly matching\u00a0the size of lithium ions. This provides\u00a0a naturally stable storage space for lithium ions, \u00a0which makes the\u00a0theoretical specific capacity reach 372mAh\/g. And the actual specific capacity of commercial products can also reach 340-360mAh\/g, meeting the basic storage requirements of graphite battery.<\/p>\n
\u00a0<\/b><\/strong><\/p>\nLong cycle life<\/b><\/strong><\/p>\nWith its unique\u00a0mechanism, the volume change rate of the layered structure during charging and discharging is only about 10%. And the crystal structure is not easily damaged, especially for artificial graphite, its\u00a0capacity retention rate remaining\u00a0\u226585% after 2000 cycles. So it\u00a0can meet the long-term usage requirements of 5-8 years and 100,000-200,000 kilometers for new energy vehicles.<\/p>\n
\u00a0<\/b><\/strong><\/p>\nExcellent fast-charging potential<\/b><\/strong><\/p>\nThe layered structure provides a fast migration channel for lithium ions, and the high crystallinity ensures good electronic conductivity.\u00a0And artificial graphite can further shorten the ion and electron conduction paths through spherical processing. So it can meet the scenario requirements of half-hour fast charging to 80% capacity for graphite anode lithium-ion batteries.<\/p>\n
\u00a0<\/b><\/strong><\/p>\nHigh safety<\/b><\/strong><\/p>\nBecause its\u00a0lithiumization potential is approximately 0.15V, and it has a low volume expansion rate. It is\u00a0close to that of metallic lithium but without forming dendrites, avoiding\u00a0puncturing the separator and causing short circuits. At the same time, it\u00a0can reduce the risk of material pulverization and active substance detachment. After optimization through coating and other processes, it can meet the safety standards for scenarios such as consumer electronics.<\/p>\n

\ucc9c\uc5f0 \ud751\uc5f0<\/b><\/strong><\/p>\nIt\u00a0uses flake graphite as the raw material, which\u00a0is first purified through flotation\u00a0using the difference in hydrophobicity to remove impurities.\u00a0And then undergoes spherification treatment which through grinding and collision to form spherical shapes, enhancing the bulk density.<\/p>\n

A<\/b><\/strong>rtificial graphite <\/b><\/strong><\/p>\nIt uses petroleum coke and other materials as the raw material, which\u00a0is first calcined at 1000 – 1300\u2103. This removes\u00a0volatile components and impurities and stabilizing the carbon structure. \u00a0Then ground and granulated, adding binders to form spherical particles\u00a0to\u00a0avoid any impact on the conductivity, stability and consistency.<\/p>\n
