Abstract

A non-aqueous battery is described which employs a molybdenum dichalcogenide negative electrode and a positive electrode of the formula Li_x Mo₆ Se₆ wherein x represents an integer ranging from 0.5 to 9.

Claims

1. A non-aqueous battery including a lithium anode, an electrolyte and a cathode, characterized in that said cathode comprises a molybdenum selenide of the formula Mo₆ Se₆.

2. A battery in accordance with claim 1 wherein said electrolyte is LiAsF₆ in 2 methyl tetrahydrofuran.

3. A non-aqueous secondary lithium battery including a cathode, an electrolyte and an anode, the cathode and anode comprising Li_x Mo₆ Se₆ wherein x represents an integer ranging from 0.5 to 9.

4. A battery in accordance with claim 3 wherein x in the anode is 9.

5. A battery in accordance with claim 3 wherein the electrolyte is LiAsF₆ in 2 methyl tetrahydrofuran.

6. A non-aqueous battery including a cathode, an electrolyte and an anode of Li_x Mo₆ Se₆ wherein x is an integer ranging from 0.5 to 9.
