Patent ID: 10044060

Abstract:
An electrochemical cell for a secondary battery is provided, which includes a positive electrode having an intercalation cathode material of treated smectite; a negative electrode material having an anode material containing magnesium; an electrolyte positioned in contact with at least one of the positive electrode and the negative electrode; wherein the electrolyte comprises a solvent in which magnesium chloride, aluminum chloride, and, optionally, magnesium hexamethyldisilazide are dissolved. The solvent is one or more of 2-methyl tetrahydrofuran; 2,5-dimethyl pyridine; 2,6-dimethyl pyridine; 3,5-dimethyl pyridine; 2,5-diethyl pyridine; 2-methyl-5-ethyl-pyridine; 2-ethyl-5-methyl-pyridine; 5-ethyl-3-methyl-pyridine; and 3-ethyl-5-methyl pyridine; and, optionally, pinene and/or ocimene.
