摘要： Lithium dopant is introduced into lithium rich high capacity positive electrode active materials as a substitution for manganese within the complex metal oxides. In some embodiments, the lithium doped compositions can be written in a two component notation as x.Li2MnO3.(1−x)LiNiu+ΔMnu−Δ−dLidCowO2, where d ranges from about 0.004 to about 0.25 and 2u+w is approximately equal to 1. The materials are believed to form a layer-layer composite crystal structure that has very good cycling properties at high voltages, although the materials exhibit significant first cycle irreversible capacity loss.

摘要： Supplemental lithium can be used to stabilize lithium ion batteries with lithium rich metal oxides as the positive electrode active material. Dramatic improvements in the specific capacity at long cycling have been obtained. The supplemental lithium can be provided with the negative electrode, or alternatively as a sacrificial material that is subsequently driven into the negative electrode active material. The supplemental lithium can be provided to the negative electrode active material prior to assembly of the battery using electrochemical deposition. The positive electrode active materials can comprise a layered-layered structure comprising manganese as well as nickel and/or cobalt.
