Synthesis, characterization and electrochemical performance of Li2MnSiO4/C cathode material by solid-state reaction

A novel approach to employ Li2MnSiO4 as anode active material for lithium batteries

“…The presence of impurity phases like MnO and less amount of Li 2 SiO 3 are unavoidable during the synthesis process. A similar kind of impurity phases are noticed by the researchers during the synthesis of Li 2 MnSiO 4 powders by various approaches [5][6][7][8][9][10]. Abnormal pressure conditions provides the MnO and Li 2 SiO 3 free Li 2 MnSiO 4 phase.…”

“…In the same line, for the first of its kind, lithium orthosilicate material (e.g., Li 2 MnSiO 4 ) has been subjected to investigate as an anode material for lithium batteries. The advantage of using such silicate groups are low cost, high theoretical capacity, environmental benignity, and ease to prepare [5][6][7][8][9].…”

Effect of Mn substitution on the structural, morphological and electrochemical behaviors of Li2Fe1−xMnxSiO4 synthesized via citric acid assisted sol–gel method

“…However, the theoretical capacity of LiFePO 4 is limited to 170 mAh g −1 based on one lithium ion in its formula [5]. Therefore, Li 2 MSiO 4 (M is a divalent transition metal), which has two lithium ions per formula unit, has attracted great interest [6].…”

C/Li2MnSiO4 Nanocomposite Cathode Material for Li-Ion Batteries

“…During last few years several different technics of Li2MnSiO4 synthesis were proposed. Hydrothermal synthesis [21][22][23][24] as well as solid-state reactions [25][26][27][28] can lead to one phase product but the control of the grain size is significantly limited. Sol-gel method is one of the soft chemistry techniques which can be used in synthesis of nanosized lithium orthosilicates [29][30][31][32][33].…”
