Abstract

A poorly crystalline mixed metal manganese oxide material. The mixed metal manganese oxide material may be used for making a cathode for a rechargeable battery. Generally, the mixed metal manganese oxide includes: manganese oxide; copper, silver, gold, or a combination thereof; a first additional cation selected from the group consisting of: bismuth, lead, and mixtures thereof; and a second additional cation selected from the group consisting of: lithium, sodium, potassium, cesium, rubidium, beryllium, magnesium, calcium, strontium, barium, NR4+, or a combination thereof, with R being, hydrogen, an alkyl group, an aryl group, or combinations thereof. The amorphous composition has an essentially amorphous x-ray powder diffraction pattern.
