Batteries are disclosed. In some embodiments, a battery includes a cathode having a composition that includes a manganese oxide. The composition has an X-ray diffraction pattern with a first peak at about 18 degrees, a second peak at about 22 degrees, and a third peak at about 32 degrees.

Battery cathodes

Batteries and methods of making batteries are disclosed. In some embodiments, a method of making a battery can include contacting a manganese oxide with lithium hydroxide and lithium bromide and/or lithium chloride, and incorporating the manganese oxide into a cathode of the battery.

A primary lithium cell having an anode comprising lithium and a cathode comprising electrochemically active material selected from copper vanadates having the formula CuVOor CuVOor mixtures thereof. The cathode can include a manganese dioxide in admixture with said copper vanadates. The cell exhibits higher capacity and energy output than conventional lithium cells having an anode comprising lithium and cathode comprising manganese dioxide.
