    Study of Compatible Anode for Silicate-Based Cathode Material
    (Springer Science and Business Media Deutschland GmbH, 2023-05-21T00:00:00) Pateriya, Ravi Vikash; Tanwar, Shweta; Sharma, A.L.
    In the present paper, we have discussed the compatibility of suitable anode material with synthesized Li2MnSiO4 cathode material. The Li2MnSiO4 cathode material was synthesized by hydrothermal technique. The structural and electrochemical analysis were done by XRD, FTIR, and electrochemical measurement by cell assembly taking different materials as the anode. Cyclic voltammetry results show that cell prepared with Li2MnSiO4 as cathode and activated carbon as anode delivered a specific capacity of 53.07 mAh g?1 and graphite specific capacity of 10.21 mAh g?1 was calculated. Charge transfer resistance (Rct) of 6 and 7 ? were observed for cell with activated carbon and graphite anode respectively. Initial discharge capacity for activated carbon as an anode was recorded to be 70.54 and 3.97 mAh g?1 for anode with graphite. The results associated with activated carbon and Li2MnSiO4 as anode and cathode material appear to be compatible materials in Li-ion battery application. � 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

    A critical review on orthosilicate Li2MSiO4 (M = Fe, Mn) electrode materials for Li ion batteries
    (Institute of Physics, 2023-05-10T00:00:00) Pateriya, Ravi Vikash; Tanwar, Shweta; Sharma, A.L.
    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. � 2023 IOP Publishing Ltd.
