Patent ID: 8080340

Claim:
An activated electrode for a non-aqueous electrochemical cell, having as a precursor thereof, a lithium metal oxide with the formula: x{z Li 2 MnO 3 •(1- z )LiM′O 2 }•(1- x )LiMn 2−y M y O 4 for 0<x<1, 0≦y≦0.5, and 0<z<1, comprising layered zLi 2 MnO 3 .(1-z)LiM′O 2 and spinel LiMn 2−y M y O 4 components, physically mixed with one another or separated from one another in a compartmentalized electrode, in which M is one or more metal ions, and in which M′ is selected from one or more first-row transition metal ions, said activated electrode being activated by removing lithium, lithia, or a combination thereof, from said precursor.
