“…The addition of LiClO4, however, causes the peak shift to lower temperatures (Tm = 60 °C), combined with a decrease in peak intensity. That lowers the melting temperature has been reported for PEO16LiClO4 electrolytes before [20,35] and is attributed to the complex formation between the Li cation and the polymer chain. The calculated crystallinity decreases to 36%, 27%, and 20% for SPE, SPE-10, and SPE-15, respectively, showing a strong influence of the Li salt on PEOs crystallization.…”

Mechanical and electrochemical stability are key issues for large-scale production of solid state Li-ion batteries. Polymer electrolytes can provide good ionic conductivity, but mechanical strength needs to be improved. In this study, we investigate the correlation of mechanical and electrical properties of poly (ethylene oxide) (PEO)-based solid electrolytes for Li-ion batteries. The influence of alumina and LiClO4 addition are investigated. Differential scanning calorimetry (DSC) is used to study the thermal behavior of salt-free and salt-containing samples and to identify the melting temperature. Dynamic mechanical analysis reveals the elastic properties as a function of temperature. Electrochemical properties are investigated using impedance spectroscopy. It is found that addition of alumina increases mechanical strength, while LiClO4 decreases it. Addition of LiClO4 and Al2O3 increases ionic conductivity and improves mechanical properties. However, there is no overlapping window of high mechanical strength and high ionic conductivity.

Composite laminates can exhibit the nonlinear properties due to the fiber/matrix interface debonding and matrix plastic deformation. In this paper, by incorporating the interface stress-displacement relations between fibers and matrix, as well as the viscoplastic constitutive model for describing plastic behaviors of matrix materials, a micromechanical model is used to investigate the failure strength of the composites with imperfect interface bonding. Meanwhile, the classic laminate theory, which provides the relation between micro- and macroscale responses for composite laminates, is employed. Theory results show good consistency with the experimental data under unidirectional tensile conditions at both 23°C and 650°C. On this basis, the interface debonding influences on the failure strength of the [0/90]sand [0/±45/90]scomposite laminates are studied. The numerical results show that all of the unidirectional (UD) laminates with imperfect interface bonding provide a sharp decrease in failure strength in theσxx-σyyplane at 23°C. However, the decreasing is restricted in some specific region. In addition, for [0/90]sand [0/±45/90]scomposite laminates, the debonding interface influences on the failure envelope can be ignored when the working temperature is increased to 650°C.

“…Batteries available in the market either use aqueous electrolytes (e.g., lead acid, Ni/Cd batteries) or organic electrolytes (Li‐ion battery) . Polymer electrolytes are in great demand because they can lead to compact, flexible, leakage free, laminated solid‐state structure available in different geometries . Rechargeable battery technology, based on lead acid batteries, Ni‐MH, Ni‐Cd, lithium batteries, although highly competitive are still not sufficient to meet the energy storage requirements for future due to various reasons including cost barrier, inherent safety and growing environment concerns .…”

A novel magnesium (Mg) ion conducting nanocomposite gel polymer electrolyte (GPE) films comprising a solution of Mg‐salt, Mg trifluoromethanesulfonate [Mg‐triflate or Mg(Tf)2] in a mixture of ethylene carbonate (EC) and propylene carbonate (PC), entrapped in a host polymer poly(vinylidenefluoride‐hexafluoropropylene) (PVdF‐HFP) has been reported. The effect of dispersion of nanosized passive filler aluminum oxide (Al2O3) and active filler Mg aluminate (MgAl2O4) in the films was studied. Free standing transparent nanocomposite films are obtained with excellent dimensional stability. The filler‐polymer interactions and possible conformational changes in the host polymer PVdF‐HFP due to the liquid electrolyte entrapmentment and dispersion of nanosized Al2O3 and MgAl2O4 fillers are examined by X‐ray diffraction, field emission scanning electron microscopy, and tensile strength measurement. A nanocomposite films with 30 wt% Al2O3 and 20 wt% MgAl2O4 fillers offer maximum ionic conductivity of 3.3 × 10−3 and 4.0 × 10−3 S cm−1, respectively, at room temperature. The temperature dependence of electrical conductivity of undispersed and nanocomposites GPE follows the Vogel‐Tammen‐Fulcher behavior. The Mg ion conduction in the nanocomposites GPE films is confirmed from electrochemical impedance spectroscopy, cyclic voltammetry, and transport number measurement. The Mg2+ ion transport number has been found to be significantly enhanced up to 0.66 for the dispersion of 20 wt% MgAl2O4 nanofiller, indicating a substantial enhancement in Mg2+ ion conductivity. The nanocomposites films possess a good electrochemical stability window, which indicates their potential applicability as electrolytes in ionic devices including Mg batteries. POLYM.
