Thermal properties of graphite

The thermal properties of conductivity and expansion are strongly influenced by the anisotropy of the graphite crystal. The thermal conductivity (K) is the time rate of transfer of heat by conduction. In graphite, it occurs essentially by lattice vibration and is

Solutions for the problems of silicon–carbon anode

The composite also possesses good rate capability, and up to 89.3% of the reversible capacity can be recovered at 1.0 A g −1. Graphite ensures the structural stability of the composite and help the dispersion of Si particles. Figure 15.

High capacity graphite

The high rate capability of different types of graphite already shown in a recent study [41] is hence affected only little for the silicon coated "compound" material. As discussed in the introduction, the main problem of silicon and comparable materials (tin, antimony, aluminium) is the important volume change upon the electrochemical reaction with lithium.
