“…The combustion method (glycine-nitrate pyrolysis) has been reported by Chitra et al and Julien et al [29,30]. In this technique, stoichiometric amounts of Li-, Ni-, and Mnnitrate salts were dissolved in triple-distilled water with a small proportion of ethanol and aqueous solution of glycine (amino-acetic acid, NH 2 CH 2 COOH).…”

We present the synthesis, characterization, and electrode behavior of LiNi 0.5 Mn 1.5 O 4 spinels prepared by the wet-chemical method via citrate precursors. The phase evolution was studied as a function of nickel substitution and upon intercalation and deintercalation of Li ions. Characterization methods include X-ray diffraction, SEM, Raman, Fourier transform infrared, superconducting quantum interference device, and electron spin resonance.

“…The materials were directly ground in argon atmosphere using a Spex 8000 mixer mill that generates normal mechanical strain with various grinding times. The electrochemically deintercalated LixMn204 samples were prepared as described elsewhere using laboratory-scale lithium cells employing a non-aqueous electrolyte [15]. The galvanostatic charge-discharge cycles were performed on a MacPile Macintosh controlled apparatus at a slow scan mode (i.e.…”

The aim of this work is to determine the vibrational properties of manganese oxide frameworks and their lithium intercalates used as positive electrode material in Li-ion batteries. Raman and FTIR spectroscopies yield reliable description of material structure in which distortion of the basal MnO6 octahedra may be expected. Lattice dynamics are studied using either a classical group theoretical analysis or a local environment model. The local arrangement in MnO2 structures is investigated for pyrolusite, ramsdellite and the Li0.33MnO2 phase. The phase evolution as a function of the degree of lithium intercalation or deintercalation is reported and analysed in series of manganospinels Li1–x+δMn2–δO4 with 0≤x≤1 and 0≤δ≤0.33. The trigonal distortion of MnO6 octahedra is evidenced by insertion of lithium ions into the [B2]O4 spinel framework. A comparison with tetragonal Li2Mn2O4 and Li6.5Mn5O12 spinels shows the influence of the Jahn-Teller effect on the Raman features for this class of materials. The local structure was characterized as a function of the mean oxidation state of manganese cations
