Synthesis and transport properties of nanostructured lithium manganese silicate (Li2MnSiO4) as Li-ion battery cathode material

Fast 3D-lithium-ion diffusion and high electronic conductivity of Li2MnSiO4 surfaces for rechargeable lithium-ion batteries

“…[39][40][41] Previous studies have demonstrated the development of Li 2 MnSiO 4 cathode materials at nanoscale 13,18,22 with improved charge/discharge kinetics. For instance, a nanostructured Li 2 -MnSiO 4 material was synthesized 42 by an easy and fast urea combustion method, which showed an extraordinarily intrinsic electronic conductivity of 4 AE 10 À8 S cm À1 . Ultrathin nanosheets of Li 2 MnSiO 4 (M ¼ Mn/Fe) 31 were also prepared by a rapid one-pot synthesis method using a mixed solvent of aqueous ethanol, and the results revealed a superior energy density of 340 mA h g À1 .…”

Rational Design of Biaxial Tensile Strain for Boosting Electronic and Ionic Conductivities of Na2MnSiO4 for Rechargeable Sodium‐Ion Batteries

“…According to the Jahn‐Teller effect, Mn−O bonding (MnO 4 ) distortion is greater than Na−O (NaO 4 ) and Si−O (SiO 4 ), which form corner‐sharing tetrahedral units with four oxygen atoms and have a similar tendency to Li 2 MnSiO 4 . [ 39 , 40 , 41 ]…”

A Critical Review on Electrochemical Properties and Significance of Orthosilicate‐Based Cathode Materials for Rechargeable Li/Na/Mg Batteries and Hybrid Supercapacitors

“…The orthorhombic (Pmn2 1 ) structure shows good discharge capacity (262 mAh g −1 at 0.1 C) with high‐capacity retention whereas the monoclinic structure (P2 1 /n) demonstrated poor discharge capacity (164 mAh g −1 at 0.1 C) and severe capacity fading. It reveals that phase purity and crystal structure have crucial role to obtain best energy storage performance of cathode material [137] . The carbon encapsulated Li 2 MSiO 4 (M=Mn, Fe) cathodes were prepared by spray pyrolysis method and structural destruction mechanism was confirmed by X‐ray absorption near the edge structure (XANES) analysis [138] .…”
