Carbon coated natural graphite

In conclusion, the surface modified natural graphite has good performance in PC based electrolyte and also meets the power requirements for hybrid electrical vehicle applications. Surface carbon coated natural graphite SLC1015 is a very promising material in high power Li-ion batteries with lower cost, reasonable safety, and low irreversible capacity.

Stable cycling was achieved in the fall 7Ah cells with a composite of spherical natural graphite coated with A1 and then stabilized with a rigid carbon coating of the disordered nature. Further investigation is needed to fally understand the effect of rigid carbon shell on the electrochemical performance of graphite-based composite materials.
