    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.

    Effect of Nano filler on PEO based polymer electrolytes for energy storage devices applications
    (Intergated Science, 2017) Sharma, P. K.; Sharma, A. K.; Sadiq, M.; Sharma, A. L.
    Ionically conducting solid polymer films have been utilized in many energy related sectors like high energy density solid polymer batteries, PEM fuel cells, and super capacitors, etc.In the present study, we report innovative study on the prepared high quality solid state free standing thin polymeric separator. In prepared free standing polymeric separator, polymer (PEO) has been used as host matrix; appropriate bulky anion salt (NaClO 4 ) as conducting species and nano ceramic filler (BaTiO 3 ) is used to enrich the mechanical and thermal stability of separator used for the device applications. The Fourier Transform Infra-Red (FTIR) result has been analysed properly of the prepared materials to look the microscopic interaction among polymer-ion, ion-ion and polymer-ion-filler interaction. Electrical conductivity results has been recorded using the impedance spectroscopy results which gives the estimated value of the order of ~10 Scm of the nano ceramic doped polymeric separator which is desirable for energy storage application. A fine correlation has been established between the electrical conductivity and FTIR results analysis
