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 ). WebJun 1, 2024 · The chemical methods are most commonly used and require oxidants to open the edge of the graphite layer. This process increases the spacing between graphite layers, allowing entrance of the intercalation agents into the interlayers in graphite to form GICs [8]. Expandable graphite could then be obtained by washing, filtration and drying …
