Adipic acid assisted sol–gel synthesis of Li2MnSiO4 nanoparticles with improved lithium storage properties

Size controlled synthesis of Li2MnSiO4 nanoparticles: Effect of calcination temperature and carbon content for high performance lithium batteries

“…2 represents the series of powder X-ray diffraction patterns of synthesized Li 2 MnSiO 4 with various temperatures. The XRD reflections showed a well defined sharp intense satellite peaks, which indicates the crystalline nature of Li 2 is also noticed other researchers by various routes [6,[8][9][10][11][12][13][14][15][16][17]. For example, de Dompablo et al [15] succeeded to prepare Li 2 MnSiO 4 material in the absence of MnO phase by varying the pressure, but in the formation of Mn 2 SiO 4 could be inevitable under such abnormal pressure conditions.…”

“…So far, very few reports could be traced for the synthesis and characterization of Li 2 MnSiO 4 either through solid state or solgel route [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. These two routes are appropriate procedures for mass production in industries.…”

Cu–Li2MnSiO4-polyaniline composite hybrids as high performance cathode for lithium batteries

“…exhibits the high theoretical capacity of >330 mA h g -1 , high thermal stability in de-lithiated state due to the presence of strong co-valent bond between Si-O, inexpensive and eco-friendliness. Indeed such polyanion framework having the lack of conductivity issues similar to olivine framework materials [10][11][12][13][14][15][16][17][18][19]. Therefore, conductive coating or composite with conducting substance is required to overcome the inherent conductivity issues.…”

“…However, the Li 2 CoSiO 4 ($4.2 V vs. Li) is not electrochemically much active compared to Mn and Fe based silicates. Recently, we extensively investigated the electrochemical properties of Li 2 MnSiO 4 prepared by various synthetic procedures like solid-state, sol-gel and hydrothermal routes [15][16][17][18][19]. Inclusion of higher amount of carbon loading is one of the efficient ways to suppress the amorphousization upon cycling, but such loading certainly dilutes the volumetric capacity of the system [16].…”

Improved electrochemical performance of zinc oxide coated lithium manganese silicate electrode for lithium-ion batteries

“…Carbon coating has been claimed as an effective method to address the shortcoming. Lee et al reported that in-situ carbon-coated Li 2 MnSiO 4 nanoparticles were prepared by employing an adipic acid-assisted sol-gel process, resulting in superior electrochemical performance [10]. Aravindan prepared Li 2 MnSiO 4 /C composite electrode with 42% carbon, which exhibited a very stable discharge behavior $140 mAh g À1 for 40 cycles at 0.05C, but such large amount of carbon certainly dilutes the volumetric capacity of the cathode [11].…”
