Beschreibung
Zusammenfassung:	A process for producing hight voltage LiNi0.5Mn1.5O4 (spinel-LNMO) cathode material is disclosed by a solid-state method or a spray dry method, particularly to have the spinel-LNMO modified in advace in the course of synthesizing process; resulted in that the spinel-LNMO cathode material can not only significantly improve conductivity of the active materials of spinel-LNMO, but also markedly solve the low electronic conductivity problem of the spinel-LNMO material, as well as improve the obtained spinel-LNMO cathode material exhibited excellent in high power characteristics and having very good cycling charge/discharge performances, and suited for making as a secondary lithium ion battery cathode.
