英文摘要Molybdate polyanion cathode materials have received lots of research interest for their high specific capacity, high cycling stability and interesting physical and chemical properties. Here, LiCr(MoO4)(2), a new deintercalation-intercalation type cathode material for lithium ion batteries, is synthesized and studied. Ultraviolet-visible-near-infrared diffuse reflection, density functional theory calculation and four-probe measurement results suggest that LiCr(MoO4)(2) possesses a narrow band gap and high electronic conductivity. Bond-valence-sum maps calculation and electrochemical impedance spectroscopy prove the fast lithium ion transport rate of LiCr(MoO4)(2). Benefiting from these advantages, LiCr(MoO4)(2) delivers a high specific capacity (250 mA h g(-1)) and good rate performances. The electrochemical reaction mechanism is studied by in situ X-ray diffraction, which indicates that the lithium ion deintercalation-intercalation is a solid solution process with Cr3+/2+ and Mo6+/5+ redox.
