“…Recently, layered LiNi x Co 1-2x Mn x O 2 transition metal mixed oxides, which can undergo oxidation to higher valences when lithium ion is removed [5,6] become the research focus due to their higher capacity, better safety and "greener" [7][8][9] compared with commercial LiCoO 2 . The mixed oxides retain the virtue of mono metal oxide such as good cycling performance of LiCoO 2 [10] , high capacity delivery of LiNiO 2 [11] , and super safety of LiMn 2 O 4 [12] . At the same time, the mixed oxides conquer their shortcomings, including the cost and environmental pollution problems of LiCoO 2 , bad stability and order of LiNiO 2 , slow fading capacity of LiMn 2 O 4 , relatively low voltages1 (typically 3V or less) of vanadium oxide.…”

The layered cathode materials LiNi x Co 1-2x Mn x O 2 (x=1/11, 2/11, 3/11, 4/11, 5/11) powders for lithium-ion batteries were synthesized by metal acetate decomposition technique. The evolution of the structural properties and electrochemical performances of LiNi x Co 1-2x Mn x O 2 with Co content decreased were investigated by X-ray diffraction (XRD) and rietveld refinement, scanning electronic microscopy (SEM) and galvanostatic charge and discharge cycle. The results showed that the appropriate substitution of Co by Ni, Mn could greatly improve the performances of the as-prepared materials in capacity, initial columbic efficiency, rate ability and cycle capability. Among the series of materials, the optimal performance belonged to Li Ni 3/11 Co 5/11 Mn 3/11 O 2 , which delivered an initial discharge capacity of 157.6 mAh•g-1 and preserved 150.4 mAh•g-1 after 30 cycles in the voltage range of 2.5～4.3 V at 0.2 C. Comparative cycle data at 0.5 C and 1.0 C were presented implying that the LiNi 3/11 Co 5/11 Mn 3/11 O 2 also had a significantly improvement in rate capability.

The results of ultrafast selected energy x-ray absorption spectroscopy (USEXAS) investigations of Ni and Zn species are presented. The USEXAS measurements described here employed characteristic x-ray radiation of L(alpha) and L(beta) from an ultrafast laser-driven W x-ray target to probe the K absorption edges of Ni and Zn, respectively. Static x-ray absorption edge spectra of six Ni and Zn species in either solid or solution form were obtained. Simulations of near-edge x-ray absorption spectra of these Ni and Zn species were carried out with FEFF. The results of USEXAS measurements were in general agreement with the theoretically simulated spectra and those measured with synchrotron x-ray radiation.
