1. An electrode within a battery, comprising:
a material represented by Li1+x+aMn1−x−y−z−wDwNiyCozO2−δ where 0≦a≦<0.1, 0.1≦x≦0.5, 0≦y<1, 0≦z≦0.5, 0<w≦0.5, and 0≦δ≦0.3, the material comprising a monoclinic phase and a layered oxide phase; wherein Dw comprises Ru and Sn and wherein one of y or z is non-zero and the monoclinic phase is represented by Li2MnO3 and comprises a dopant at a Mn site of the monoclinic phase; and wherein the battery is characterized by reduced voltage fade as compared to a control battery comprising a control electrode formed from a control material represented by Li1+x+aMn1−x−y−z−wDwNiyCozO2−δ where 0≦a≦0.1, 0.1≦x≦0.5, 0≦y<1, 0≦z≦0.5, and 0≦δ≦0.3. |
