Protective active nitrides as additives to nonaqueous cathode materials

摘要

A method for preparing stable non-stoichiometric cathode material to provide cathodes useful in non-aqueous electrochemical cells having an active metal (e.g. lithium) anode. The method comprises reducing the non-stoichiometric cathode material (e.g. manganese dioxide) with the active metal or a precursor compound of said active metal to form a compound of the active metal and stoichiometric active cathode material.
