“…In this case, t Li þ of EC-and PC-plasticized sample is 0.23 and 0.29, respectively. The low t Li þ indicates that ionic conductivity would mainly depend on anion transport [22]. The electrochemical stability window of the GPE was performed to observe the ability of GPE to endure the operating voltage of the battery system.…”

MG30 is natural rubber grafted with 30% poly (methyl methacrylate). Gel polymer electrolytes containing MG30-LiCF 3 SO 3 -X (X=propylene carbonate, ethylene carbonate) are prepared by solution casting technique. The polymer-salt complexes were investigated using Fouriertransformed infrared. The ionic conductivity of the electrolytes are determined by the ac impedance studies over the temperature range of 303-383 K and is observed to obey the Vogel-Tamman-Fulcher (VTF) rule. The Li + transference number obtained using the Bruce and Vincent method is <0.3. The Li/Li + interface stability is established and the electrolytes were found to be able to withstand a voltage of more than 4.2 V.

This article reviews the PEO-based electrolytes for lithium-ion batteries.Poly(ethylene oxide) (PEO) based materials are widely considered as promising candidates of polymer hosts in solid-state electrolytes for high energy density secondary lithium batteries. They have several specific advantages such as high safety, easy fabrication, low cost, high energy density, good electrochemical stability, and excellent compatibility with lithium salt. However, the typical linear PEO does not reach the production requirement because its insufficient ionic conductivity due to the high crystallinity of the ethylene oxide (EO) chains, which can restrain the ionic transition due to the stiff structure especially at low temperature. The scientists have explored different approaches to reduce the crystallinity hence to improve the ionic conductivity of PEO-based electrolytes, including: blending, modifying and making PEO derivatives etc. This review is focused on surveying the recent developments and issues about PEO-based electrolytes for lithium-ion batteries.

“…7 Solid polymer batteries, having good stability and cycle performance, have also been proposed. 8 It is important to point out that these "solid-state batteries" have the favorable characteristic of avoiding lithium dendrite deposition and hence, of preventing short circuits, in cells using lithium metal as the anode active material. In addition, solid electrolytes are expected to be safer than common nonaqueous electrolyte media, because of their low or negligible vapor pressure.…”

Lithium-sulfur (Li-S) batteries are promising candidates for next generation electrical energy storage devices due to their high specific energy. Despite intense research, there are still a number of technical challenges in developing a high performance Li-S battery. To elucidate the issues, an all solid-state Li-S battery was fabricated using Li 3 PS 4 solid electrolyte. Most of the theoretical capacity of sulfur, 1600 mAhg −1 was attained in the initial discharge-charge cycles with a high coulombic efficiency approaching 99%. To verify the benefit of the solid state electrolyte, galvanostatic stripping-deposition tests were also carried out on a symmetrical Li/Li cell and compared with those of a liquid electrolyte (1 M-lithium bis(trifluoromethane sulfonyl) imide (LiTFSI) in a mixture of 1,3-dioxolane (DOL)-diethoxyethane (DEE)). The kinetics and thermodynamics of the solid-state cell are discussed from the viewpoint of the charge transfer processes. This study demonstrates both the merits and drawbacks of using the solid sulfide electrolyte in a Li-S battery and facilitates the further improvement of this important high energy storage device. Lithium-sulfur (Li-S) batteries are attracting growing interest owing to their high specific energy above 3000 Whkg −1 (active material). However, before this technology can be used in practice, there are some significant challenges to overcome, including red-ox shuttle of polysulfides as well as poor lithium cycle performance.The polysulfide redox shuttle originates from the dissolution of the cathode material into the organic electrolyte. So far, various approaches have been suggested to solve the red-ox shuttle issue. LiNO 3 is a well-known additive for optimizing the solid electrolyte interphase (SEI) on lithium metal electrode, such as to block the deposition of polysulfides.1,2 An ionommer (e.g., Nafion) has also been proposed for preventing the polysulfide migration 3 and a buffer solution containing polysulfides can facilitate a good cycle ability as well. 4 The poor lithium cycle performance is due to the consumption of lithium metal during the charge-discharge process. It is well known that the lithium cycling response is primarily determined by the type of electrolyte to which it is in contact. 5,6 In the development of lithiummetal secondary batteries the Figure of Merit (FOM) is the parameter used to evaluate the lithium cycling ability. 5,6 Although lithium metal has a high specific capacity of 3862 mAhg −1 , its effective degree of utilization (i.e., the lithium loss relative to the amount of total input lithium metal) has to be taken into account. Generally, a valid parameter to determine the cycle ability of the lithium anode is the efficiency. For instance, it is difficult to achieve an efficiency higher than 99% for lithium cycling in a typical liquid electrolyte cell due to losses during its dissolution-deposition reaction. Therefore, the improvement of the FOM of a liquid electrolyte Li-S battery has been a major challenge to enhance the charge-disc...
