a Room-temperature Fourier transform infrared signatures of the pristine m-Li2MnSiO4 and the m-Li2MnSiO4/C (sample D) as exemplified by the absence of vibrational features in the spectrum. b Raman spectrum of the pristine m-Li2MnSiO4 and m-Li2MnSiO4/C (sample D) recorded at room temperature. The distinct peaks observed in the higher energy region (1200–2000 cm⁻¹) are assigned to the deconvolutions of carbon bands

Li2MnSiO4 has attracted significant attention as cathode material for lithium ion batteries due to its structural diversity, abundance, low cost, thermal stability, and high theoretical capacity (330 mAh g⁻¹). However, it suffers from low electronic conductivity, poor cycling performance, and limited reversible capacity. To overcome these deficienc...

Lithium metal batteries are a promising replacement for lithium-ion batteries due to their ability to achieve high energy densities. However, the unsafe operation of the lithium battery due to the formation and sprouting of dendrites through the separator limits their commercial application. We obtained a gel-polymer electrolyte based on a Nafion c...

The development of novel electrode materials with good electrochemical performances is necessary for the expanded and varied applications of lithium-ion batteries, and this development heavily relies on cathode materials. Due to excellent thermal stability, abundance, low cost, and environmental friendliness, orthosilicate cathode materials Li2MSiO4 (M= Fe, Mn) has received a lot of attention recently. The present review article gives a glimpse into the characteristics, advantages, and recent progress of orthosilicate cathode materials. This review starts with a brief history and working mechanism of batteries, the advantages of cathode materials followed by types of cathode materials, various synthesis methods, and different techniques used for their characterization. The most current initiatives to enhance orthosilicate Li2MSiO4 type electrochemical performances were introduced in this review. We provide a critical assessment of the efficient modification techniques for the orthosilicate Li2MSiO4 type cathode materials in particular. These potential cathode materials' synthesis, structure, morphologies, and particularly electrochemical performances have been thoroughly examined. This evaluation, we hope, will clarify the sustained advancement of high-efficiency and reasonably priced Li-ion batteries
