Organic/inorganic hybrid membranes that are based on GTT (GPTMS-TMES-TPTE) system while using 3-Glycidoxypropyl-trimethoxysilane (GPTMS), Trimethyletoxisilane (TMES), and Trimethylolpropane triglycidyl ether (TPTE) as precursors have been obtained while using a combination of organic polymerization and sol-gel synthesis to be used as electrolytes in Li-ion batteries. Self-supported materials and thin-films solid hybrid electrolytes that were doped with Lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) were prepared. The hybrid network is based on highly cross-linked structures with high ionic conductivity. The dependency of the crosslinked hybrid structure and polymerization grade on ionic conductivity is studied. Ionic conductivity depends on triepoxy precursor (TPTE) and the accessibility of Li ions in the organic network, reaching a maximum ionic conductivity of 1.3 × 10−4 and 1.4 × 10−3 S cm−1 at room temperature and 60 °C, respectively. A wide electrochemical stability window in the range of 1.5–5 V facilitates its use as solid electrolytes in next-generation of Li-ion batteries.

Sol Gel Synthesis

Herein, the spinel-layered cathode material Li1.33MnTiO4+z (0.8LiMnTiO4•0.2Li2Mn0.5Ti0.5O3) is investigated for the purpose of developing a high-capacity, low-cost, and environmentally friendly cathode for Li-ion batteries. Sol-gel synthesis is conducted and the relationships between synthesis temperature, structure, and electrochemical performance of the cathodes are studied. The effects of size and purity on the capacities of these cathodes are discussed. The samples fired at 500 and 600 °C contain an impurity phase of TiO2, thus delivering capacities of 208 and 210 mAh g−1 at C/10, respectively. The sample fired at 700 °C without the impurity phase of TiO2 shows a high capacity of 222 mAh g−1 at C/10 and capacity retention of 90.5% after 100 cycles at 1C.
