Title: LiNi{sub x}Cu{sub 0.5{minus}x}Mn{sub 1.5}O{sub 4} spinel electrodes, superior high-potential cathode materials for Li batteries. 1: Electrochemical and structural studies

Abstract

LiNi{sub x}Cu{sub 0.5{minus}x}Mn{sub 1.5}O{sub 4} (0 {le} x {le} 0.5) spinel materials that are of interest as electrodes for lithium-ion batteries have been studied by crystallographic and electrochemical methods. Electrochemical results show that the inclusion of Ni into the Cu-modified spinel increases the overall reversible capacity from 72 mAh/g with LiCu{sub 0.5}Mn{sub 1.5}O{sub 4} (x = 0) at 4.95 V to 120 mAh/g with LiNi{sub 0.5}Mn{sub 1.5}O{sub 4} (x = 0.5) at 4.6 V. The Cu-rich spinels in the LiNi{sub x}Cu{sub 0.5{minus}x}Mn{sub 1.5}O{sub 4} system show enhanced stability upon cycling. These spinel products are difficult to prepare in single-phase form. Neutron diffraction data show that the end members LiNi{sub 0.5}Mn{sub 1.5}O{sub 4} was determined from a combined X-ray and neutron diffraction profile refinement to be Li{sub 0.97}Ni{sub 0.42}Mn{sub 1.61}O{sub 4}.
