Natural and synthetic graphites are used as battery material in many applications. Natural graphite can form in the earth’s crust at about 750 °C and 5000 Bar pressure, but very slowly (requiring millions of years).
Battery-grade graphite was fabricated in 13 min at a low temperature of 1100 °C. Fast carbonation is achieved by a multi-physics field carbonization coupling with a Ni catalyst. Molecular dynamics revealed the exceptional kinetics carbonization by MPF. The obtained graphite anode provides a reversible Li + storage capacity of 370.7 mAh g −1.
Graphite was first ball-milled and modified and then electrolyzed with SiO 2 to reduce and deposit Si on the surface and sides of the graphite. The electrochemical performance of the composite anode after spheronization and carbon coating encapsulation was greatly improved.
At the beginning of the 21st century, aiming at improving battery energy density and lifespan, new modified graphite materials such as silicon-graphite (Si/G) composites and graphene were explored but limited by cost and stability.
It also increases the service life of the batteries. Another advantage of graphite rounding: it improves the intercalation kinetics - and thus the conductivity - of the lithium ions in the battery anode. However, the existing processes for graphite spheroidisation only produce a low yield of about 30 to 50 %.
