Abstract We report on the synthesis, properties, and ion conductivity of a solid polymer electrolyte produced from polytetrahydrofuran (PTHF) photo-crosslinked with 3,4-epoxycyclohexylmethyl 3ʹ,4ʹ-epoxycyclohexane carboxylate (Epoxy), via an active monomer mechanism that facilitates the reaction of the native hydroxyl and epoxide end-groups. Crosslinked samples were loaded with different quantities of lithium tetrafluoroborate (LiBF4) and evaluated by electrochemical spectroscopy impedance (EIS) to determine their ionic conductivity. An increase in lithium salt loading led to an increase in ionic transport, reaching competitive conductivities of up to 10-3 S/cm at temperatures typical for battery operation. Thermal analysis confirms the amorphous structure and high thermal stability (30-90°). The mechanical analysis shows the materials possess suitable stiffness for applications. The results demonstrate a new synthetic route to tunable crosslinked networks for a broad range of chemical building blocks to achieve high lithium-ion conduction and attain desirable thermal and mechanical properties.

<p>Electrolyte plays a key role in lithium-ion battery system. Safety and reliability factor was the main background of the development of solid polymer electrolyte as a substitute the conventional electrolyte in liquid form. Preparation and characterisation of a polymer electrolyte system based on lithium bis(oxalato) borate or LiBOB salt and PVdF as the host matrix has been performed. LiBOB salt and PVdF polymer were dissolved in DMAC solvent followed by solid polymer electrolyte forming by means of doctor blade method. The membranes obtained were characterised by FT-IR, XRD, and EIS. It was shown that the electrolyte exhibited higher room ionic conductivity with the increase of salt concentration, with highest conductivity value of 1.22 × 10<sup>-6</sup> Scm<sup>-1</sup> for 70% LiBOB concentration.</p><p><strong> </strong></p>
