WebMar 9, 2024 · The AlCl 4− ions intercalate through the NG lattice, generating a volumetric expansion of the cathode and thereby decreasing the porosity, [ 11, 39] which almost disappears at the fully charged state. The release of AlCl 4− induces cathode microporosity, which grows during discharge (Figure 4 ). A number of metal halides intercalate into graphite. The chloride derivatives have been most extensively studied. Examples include MCl2 (M = Zn, Ni, Cu, Mn), MCl3 (M = Al, Fe, Ga), MCl4 (M = Zr, Pt), etc. [1] The materials consists of layers of close-packed metal halide layers between sheets of carbon.
