Patent ID: 7732096

Claim:
An electrode for a non-aqueous lithium cell, comprising a lithium metal oxide having the formula xLi 2−y H y O.xM′O 2 .(1−x)Li 1−z H z MO 2 in which 0<x<1, 0<y<1 and 0<z<1 made from a lithium metal oxide precursor material having the formula xLi 2 M′O 3 .(1−x)LiMO 2 , in which 0≦x<1, and in which M is a non-lithium metal ion with an average trivalent oxidation state selected from two or more first-row transition metals or lighter metal elements in the periodic table, and M′ is one or more ions with an average tetravalent oxidation state selected from the first- and second-row transition metal elements and Sn, the xLi 2−y H y O.xM′O 2 .(1−x)Li 1−z H z MO 2 being made by preconditioning the precursor material in a proton-containing medium with a pH<7.0 including one or n-tore of phosphoric acid, sulfuric acid, nitric acid, acetic acid, hydrochloric acid or hydrofluoric acid.
