Since the commercialization of lithium-ion batteries, graphite has been the uncontested material of choice as the negative electrode host structure, and it has therefore been pivotal for their ubiquitous adoption and implementation.
Negative materials for next-generation lithium-ion batteries with fast-charging and high-energy density were introduced. Lithium-ion batteries (LIB) have attracted extensive attention because of their high energy density, good safety performance and excellent cycling performance. At present, the main anode material is still graphite.
In addition, the known partial exfoliation of some SFG6-HT graphite particles in the electrode, 26 which is combined with a significant volume increase of the graphite particles, increases the mechanical stress on the electrode and thus deteriorates the particle-particle contact in the electrode during the first electrochemical lithium insertion.
