Effect of Cobalt Incorporation and Lithium Enrichment in Lithium Nickel Manganese Oxides

Candidate cathode materials of cobalt-incorporated and lithium-enriched have been prepared by a coprecipitation method and a solid-state reaction. We systematically investigated the effect of both cobalt presence and lithium concentration on the structure, physical properties, and electrochemical behavior of the studied samples. The electrochemical performance of the cobalt-containing compounds showed much less dependence on the variation in the...
