Abstract:
1. A process of forming an expanded hexagonal layered mineral (HLM), comprising: immersing at least a portion of an HLM rock in a slurry constituted by a mixture of expanded HLM rock, a metal salt and an organic solvent, with the slurry having the following composition: HLM rock: 15-20 wt %; HLM flake: 0.1-5 wt %; and an electrolyte of 80-160 g/L of LiClO 4 (5-10 wt %) in propylene carbonate: 70-80 wt %; wherein the HLM rock has atomic interlayers each having an hexagonal lattice structure, with the atomic interlayers separated by interlayer spacings; electrochemically charging the HLM rock by incorporating the HLM rock into at least one electrode and performing electrolysis through the slurry using the at least one electrode, thereby introducing the organic solvent and ions from the metal salt from the slurry into the interlayer spacings of the HLM rock to form 1 expanding the 1
