Title
(EN) Ultrahigh voltage mixed valence materials
Abstract
(EN)

A series of electroactive insertion compounds, LiM.sub.y.sup.II M.sub.z.sup.III Mn.sub.l.sup.III Mn.sub.q.sup.IV O.sub.4 (0<y+z.ltoreq.0.5, y+z+l+q=2), where M=any transition metal or combination of metals, for application in non-aqueous batteries, capacitors, and superconducting materials, are disclosed. These newly synthesized compounds are unique in that they contain at least two mixed valence elements, thereby allowing the reversible intercalation of lithium cations at potentials near 4.7-5.1 V vs. lithium. Also disclosed are novel copper insertion compounds of the formula LiM.sub.y Cu.sub.0.5-y Mn.sub.1.5 O.sub.4 (0.ltoreq.y.ltoreq.0.49), where M=one or more metals or transition metals. Such materials have also been found to be remarkably stable at this voltage upon repeated cycling. -GOVT PAC STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT PAR Part of the work leading to this invention was carried out with United States government support provided under Department of Defense Contract No. DAA-B07-97-C-D-304.
