摘要:
This invention generally relates to electrochemical cells utilizing magnesium anodes, new solutions and intercalation cathodes. The present invention is a new rechargeable magnesium battery based on magnesium metal as an anode material, a modified Chevrel phase as an intercalation cathode for magnesium ions and new electrolyte solution from which magnesium can be deposited reversibly, which have a very wide electrochemical window. The Chevrel phase compound is represented by the formula Mo6S8-YSeY in which y is higher than 0 and lower than 2 or by the formula MXMo6S8 in which M is selected from the group comprising of copper (Cu), nickel (Ni), silver (Ag) and/or any other transition metal; further wherein x is higher than 0 and lower than 2.
