A Li-ion battery consists of a intercalated lithium compound cathode (typically lithium cobalt oxide, LiCoO 2) and a carbon-based anode (typically graphite), as seen in Figure 2A. Usually the active electrode materials are coated on one side of a current collecting foil.
LIB comprises three primary components, which are an anode, a cathode, and an electrolyte. During the process of charging LIBs, Li + ions are extracted from the cathode. As this cycle progresses, the disassembled Li + ions travel through the electrolyte and migrate to the anode, facilitating energy storage within the LIBs.
Thus, an ideal cathode in a Li-ion battery should be composed of a solid host material containing a network structure that promotes the intercalation/de-intercalation of Li + ions. However, major problem with early lithium metal-based batteries was the deposition and build-up of surface lithium on the anode to form dendrites.
