Newly Elaborated Multipurpose Polymer Electrolyte Encompassing RTILs for Smart Energy-Efficient Devices

Abstract

Profoundly ion-conducting, self-standing, and tack-free ethylene oxide-based polymer electrolytes encompassing a room-temperature ionic liquid (RTIL) with specific amounts of lithium salt are successfully prepared via a rapid and easily upscalable process including a UV irradiation step. All prepared materials are thoroughly characterized in terms of their physical, chemical, and morphological properties and eventually galvanostatically cycled in lab-scale lithium batteries (LIBs) exploiting a novel direct polymerization procedure to get intimate electrode/electrolyte interfacial characteristics. The promising multipurpose characteristics of the newly elaborated materials are demonstrated by testing them in dye-sensitized solar cells (DSSCs), where the introduction of the iodine/iodide-based redox mediator in the polymer matrix assured the functioning of a lab-scale test cell with conversion efficiency exceeding 6% at 1 sun. The reported results enlighten the promising prospects of the material to be successfully implemented as stable, durable, and efficient electrolyte in next-generation energy conversion and storage devices.

Facile fabrication and characterization of polyimide nanofiber reinforced photocured hybrid electrolyte for Li‐ion batteries

“…Ultraviolet-coated PI membranes showed high ionic conductivities and sufficient electrochemical stability window. The fiber free UV-cured electrolytes shows potential stability above 5.5 V which is compatible with literature, [46][47][48] while the UV-coated PI membrane electrolytes show potential stability above 5.5 V even 6 V versus Li + /Li. Three factors on electrochemical stability were investigated: the addition of MEMO, the integration of PI fibers to the photocured electrolyte and the addition of PEO containing crosslinker.…”

Design of Phosphonated Imidazolium-Based Ionic Liquids Grafted on γ-Alumina: Potential Model for Hybrid Membranes

“…The most common systems are composed of ILs either impregnated or confined in matrices, which can be porous or non-porous (i.e., polymer, ceramic or hybrid matrices). These materials can have applications, for example, in batteries [2,3,4], as electrolytes [5] or as CO 2 separation systems [6,7]. Imidazolium-based ILs grafted onto the surface of porous supports are promising systems for a range of applications, including catalysis [8,9], chromatography [10,11,12] and gas separation [13,14].…”

Photostabilizing Efficiency of PVC in the Presence of Schiff Bases as Photostabilizers

“…In addition, it is important to perform efficient accelerated experiments and to investigate the effects of degradation factors of polyvinyl chloride under the required conditions of this application. Polymer materials have found a number of important applications in dye-sensitized solar cells (DSSCs) as luminescent and protective coatings [7], templates for designing new nanostructured TiO-electrodes [8], stable electrolytes [9], conductive plastic substrates [10], counter electrodes [11] and other components of solar cells [12]. Over the last 40 years, the versatility of organic chemistry has allowed significant progress in achieving control over the solid-state properties of functional organic molecules, with the attention focused on covalent bonding and on the tailoring of "intramolecular functionality".…”
