“…In recent years, blends of polyvinyl alcohol (PVA) and polyvinyl pyrrolidone (PVP) [17], PVA/Chitosan (CN) [18] and PVA/polyethylene glycol (PEG) [15] have been studied by various researchers for the preparation of lithium ion conducting blend polymer electrolytes using various lithium salts such as LiPF 6 , LiCF 3 SO 3 , LiClO 4 and LiBF 4 . These studies revealed that the blend polymer electrolyte with different lithium salts exhibit desirable conductivity but poor mechanical and electrochemical stability.…”

New solid polymer blend electrolyte films based on biodegradable polymer blend comprising of polyvinyl alcohol (PVA) and poly (N-vinyl pyrrolidone) (PVP) doped with different wt% of lithium carbonate (Li 2 CO 3 ) salt have been prepared by solution casting method. The resulting PVA/PVP/Li 2 CO 3 polymer blend electrolyte films have been characterized by various analytical techniques such as FTIR, UV-vis, XRD, TGA, polarized optical microscopy and scanning electron microscopy. The FTIR and XRD analysis confirmed the complex formation between PVA/ PVP blend and Li 2 CO 3 salt. The ionic conductivity and the dielectric properties of PVA/PVP/Li 2 CO 3 polymer blend electrolyte films were investigated using an impedance spectroscopy. It was observed that the ionic conductivity of PVA/PVP/Li 2 CO 3 electrolyte system increases as a function of Li 2 CO 3 concentration. The highest ionic conductivity was found to be 1.15 9 10 -5 S cm -1 for polymer blend electrolyte with 20 wt% Li 2 CO 3 content. On the other hand, the dielectric results revealed the non-Debye type of behaviour. The dielectric constant values indicate a strong dielectric dispersion in the studied frequency range which increases as the Li 2 CO 3 content increases. The dielectric constant as high as 1200 (e = 1201.57, 50 Hz, 150°C) and the dielectric loss well below 4 (tan d = 3.94, 50 Hz, 150°C) were obtained for polymer blend electrolytes with 25 wt% Li 2 CO 3 salt. Thus, the results obtained in the present study suggest that the PVA/PVP/ Li 2 CO 3 polymer blend electrolyte system seems to be a promising candidate for solid state battery applications.

In the present work kappa-carrageenan (KC) with different ammonium salts NH4Cl, NH4Br, and NH4I membrane were successfully synthesized by the solution casting technique. The prepared eco-friendly membrane is subjected to ionic conductivity study, XRD study, transference number studies, and then it’s compared. The ionic conductivity value for KC with 200 mg NH4Cl is 1.81× 10-4 S/cm, KC with 300 mg NH4Br is 2.80× 10-3 S/cm, KC with 400 mg NH4I is 5.88× 10-5 S/cm. Among all the three, combinations the KC with 300 mg NH4Br gives high ionic conductivity. From the X-Ray Diffraction pattern, KC-NH4Cl incorporation greatly enriched the amorphous region. All the three membranes transference numbers are very close to unity. Among all the three combinations, KC with 300 mg NH4Br is the best combination for the application of fuel cell battery.

“…They have become important power sources in consumer electronic products, such as cellular phones and laptop computers. Currently carbon materials are generally used as anode materials for LIBs due to their small surface change, structural stability during cycling, high energy density, and abundance [ 1 ]. Carbon materials can be classified in several ways.…”

Mesophase soft carbon (MSC) and mesophase graphite (SMG), for use in comparative studies of high C-rate Lithium Ion Battery (LIB) anodes, were made by heating mesocarbon microbeads (MCMB) at 1300 °C and 3000 °C; respectively. The crystalline structures and morphologies of the MSC, SMG, and commercial hard carbon (HC) were investigated by X-ray diffraction, transmission electron microscopy, scanning electron microscopy, and Raman spectroscopy. Additionally, their electrochemical properties, when used as anode materials in LIBs, were also investigated. The results show that MSC has a superior charging rate capability compared to SMG and HC. This is attributed to MSC having a more extensive interlayer spacing than SMG, and a greater number of favorably-oriented pathways when compared to HC.
