An anode obtained by using the anode active material and an electrochemical device comprising the anode are also disclosed. The carbonaceous material comprises a coating layer of metal-/metalloid-carbide obtained by treating it at high temperature under inert atmosphere, wherein the coating layer has increased interfacial boding force to the carbonaceous material and thus shows minimized

ALD Coating for Anode, Cathode Materials

Targray's ALD coating solution can be applied to our natural and artificial graphite powders to create drop-in ready solutions for current lithium-ion anode chemistries. As the degradation mechanisms for anodes and cathodes are different (albeit intertwined), cells comprising both ALD coated anodes and cathodes can deliver compounding benefits.
