The goal of this investigation is connected with wishes to use the melanin for formulating the solid polymer electrolyte without the binder for Li batteries. Nature and properties of solid polymer electrolyte of the Li batteries is an important factor for ensuring the properties of Li batteries. For successful optimization the properties of Li batteries the following list includes the important requirements for the polymer electrolyte: high conductivity in wide operating temperature, chemical stability and no ignition at under high temperature - even more than 1000C, low impedance of interface between electrode and solid polymer electrolyte, special design of system - the solid polymer electrolyte in porous structure of electrode. For developing the solid polymer electrolyte without the binder we fulfill this goal includes the melanin in the solid polymer electrolyte.

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.
