WebNov 13, 2024 · In the past decades, graphite materials dominant for use as the anode in lithium-ion batteries (LIBs) [1,2,3].Despite Si-based anodes, such as nano Si particles and SiO x, which attract a lot of attention in academic circles, graphite is still playing the most important role [4,5,6].Artificial graphite (AG) is obtained from coke via ultra-high … WebGraphite. Again the carbon atoms are bonded together to make a giant structure but in this case all of the carbons are bonded to only three neighbour and are sp 2 hybridised. As the sp 2 hybridisation results in planar structures, there are giant 2 dimensional layers of carbon atoms and each layer is only weakly linked to the next layer by Van der Waal's forces.
