“…This irreversible capacity was considered to be due 6(c), it was found that the polymer electrolyte is stable up to 4.7 V, which meets the requirement for a practical lithium-ion battery. This is consistent with other reported gelled polymer electrolytes, since the electrochemical oxidation potential is mainly due to the absorbed liquid electrolyte [3,22,47,48,53]. Further research is necessery to improve the high rate performance of the lithium-ion batteries.…”

Microporous poly(vinylidene fluoride)/poly(methyl methacrylate) (PVDF/PMMA) membranes were prepared using the phase-separation method. Then, the membranes were immersed in liquid electrolyte to form polymer electrolytes. The effects of PMMA on the morphology, degree of crystallinity, porosity, and electrolyte uptake of the PVDF membrane were studied. The addition of PMMA increased the pore size, porosity and electrolyte uptake of the PVDF membrane, which in turn increased the ionic conductivity of the polymer electrolyte. The maximum ionic conductivity at room temperature was 1.21 × 10−3 S cm−1 for Sample E70. The polymer electrolyte was investigated, along with lithium iron phosphate (LiFePO4) as cathode for all solid-state lithium-ion rechargeable batteries. The lithium metal/E70/LiFePO4 cell yielded a stable discharge capacity of 133 mAh g−1 after up to 50 cycles at a current density of 8.5 mA g−1.

“…Li 2 CO 3 is not electrochemically reversible in the aprotic lithium-air battery systems, which will limit their chargeability, cycle life, and stability in lithium-air batteries. The addition of inorganic llers such as silica (SiO 2 ), or aluminum oxide (Al 2 O 3 ) or titania (TiO 2 ) nanoparticles into the electrolyte results in the enhancement of physical strength as well as the increase in the absorption level of electrolyte solution [2]. Moreover inorganic llers also act as solid plasticizers, hindering the reorganization of polymer chains and can interact with polar groups by Lewis acid-base reaction.…”

Electrolytes based on organic carbonate solvents of ethylene carbonate (EC) and diethyl carbonate (DEC) were prepared by using LiPF6 as the Li-source. Nano sized Al2O3 (50 nm) was used as a reinforcing component in order to control corrosion and Li2CO3 formation. Corrosion of the Li foil anode and electrochemical tests were performed by using EC/DEC/LiPF6 and nanocomposite EC/DEC/LiPF6/5wt.% Al2O3 electrolytes. Electrochemical tests were performed in the swagelok cells by using Li foil anode and carbon air cathode electrodes. Structural tests were carried out by using scanning electron microscopy (SEM), x-ray diraction (XRD) and Raman spectroscopy. Results revealed that incorporation of nano Al2O3 leads to a decrease of corrosion rate of Li anode and a small decrease in the capacity of the air cells.
