An electrochemical investigation of Li intercalation in the sol-gel LiMn2O4 spinel oxide

Lithium recovery by electrochemical transfer junction based on intercalation host matrix

“…1a) corresponding to the lithium ion intercalation or de-intercalation into or from the spinel, for Li x Mn 2 O 4 0≤ x≤0.5 and 0.5b x≤1 in accordance with literature [13][14][15]. The signals show reversible intercalation processes, the anodic peaks are centered at 1.01 and 1.15 V, while corresponding cathodic peaks are centered at 0.83 and 0.99 V. Fig.…”

A study on insertion/removal kinetics of lithium ion in LiCrxMn2−xO4 by using powder microelectrode

“…The most important manganese oxide is spinel lithium manganese oxide, LiMn 2 O 4 , used as the cathode materials for lithium ion battery, which is easy to prepare and has high capacity density [3][4][5]. However, its application is limited by its instability due to Jahn-Teller effect and dissolution of manganese into electrolyte during cycling of charging and discharge [6][7][8].…”

Physiochemical properties of mixed oxides of iron and silicon

“…In nature, oxides and hydroxides are mostly occurring in the form of coatings on other particles and exist in various amorphous and crystalline forms. Mixed oxides have been studied by various investigators because of their potential as advanced materials in the optical industry, as ceramics, as catalysts and for the adsorption of metals ions [3][4][5][6][7][8].…”

“…Materials prepared by sol-gel chemistry possess a high surface area and are highly porous in nature on account of which these materials have a number of applications such as insulators, ceramic precursors and catalytic supports. The versatility of sol-gel chemistry also provides a way of controlling the shape, morphology and texture properties of the final material [3,5]. It also provides a means of preparing mixed metal oxides in which mixing of various metal oxide phases can be controlled on the nanoscale.…”
