ABSTRACT:
The invention provides a battery having an electrode active material comprising a mixed-metal sulfate compound. The mixed-metal consists of at least one alkali metal and at least one transition metal. Preferably, the sulfate compound is a polysulfate having more than one SO.sub.4 group. The invention also provides novel lithium-metal-sulfate compounds and electrodes comprising such novel compounds.
