High energy density plural chalcogenide cathode-containing cell

Patent ·
OSTI ID:6424742

The present invention is directed to electric current-producing cells having specified mixed cathodes. The cells comprise: (A) an anode having as its anode-active material one or more metals selected from the group consisting of the periodic table group ia metals, group ib metals, group iia metals and group iib metals; (B) a cathode having as its cathode-active material a mixture containing: (I) one or more cathode-active, high energy density chalcogenide compounds selected from the group consisting of vsa, voa, cxs, mooz and mosz, wherein a is a numerical value of about 8 to about 2.7, wherein X is a numerical value of about 4 to about 16 and wherein Z is a numerical value of about 2.5 to about 5; and (II) one or more cathode-active, high rate chalcogenide compounds selected from the group consisting of tisy, tisey and vseywherein Y is a numerical value of about 1.8 to about 2.2; and (C) an electrolyte which is chemically inert with respect to said anode and said cathode and which permits the migration of ions between said anode and said cathode. A preferred embodiment contains a lithium-active material anode and a cathode containing a mixture of mos3 and tis2.
