“…The intensity of the C=O band in the S25 electrolyte is lower than that of a pure plant-based GPE (S0 electrolyte). This finding implies that the interaction between carbonyl and Li + salt weakens the C=O bond [ 46 ] and allows Li + the sharing of electron density with the oxygen atom. The oxygen atom serves as an electron donor to Li + ion to develop polymer electrolyte complexes.…”

In this work, a plant-based resin gel polymer electrolyte (GPE) was prepared by stereolithography (SLA) 3D printing. Lithium perchlorate (LiClO4) with a concentration between 0 wt.% and 25 wt.% was added into the plant-based resin to observe its influence on electrical and structural characteristics. Fourier transform infrared spectroscopy (FTIR) analysis showed shifts in the carbonyl, ester, and amine groups, proving that complexation between the polymer and LiClO4 had occurred. GPEs with a 20 wt.% LiClO4 (S20) showed the highest room temperature conductivity of 3.05 × 10−3 S cm−1 due to the highest number of free ions as determined from FTIR deconvolution. The mobility of free ions in S20 electrolytes was also the highest due to greater micropore formation, as observed via field emission scanning electron microscopy (FESEM) images. Transference number measurements suggest that ionic mobility plays a pivotal role in influencing the conductivity of S20 electrolytes. Based on this work, it can be concluded that the plant-based resin GPE with LiClO4 is suitable for future electrochemical applications.

Solid polymer electrolyte (SPE)‐based lithium batteries have easy processing and safety for energy vehicles and storage. However, the preparation process of SPEs mostly used a lot of organic solvents, which will threaten human living space and body health. Herein, a novel green solid polymer electrolyte (ionic liquid type waterborne polyurethane, IWPUS) without no organic solvents was prepared from hybrids of ionic liquid‐based waterborne polyurethane (IWPU) and LiClO4. The structure and properties of IWPUS were investigated by IR, SEM, XRD, TGA, ion conductivity test. The results showed that Li+ of LiClO4 could coordinate with CO and COC in the polyurethane matrix. LiClO4 had been well dispersed in IWPU. The conductivity of IWPUS increased with the increase of LiClO4 content. The higher conductivity of IWPUS with 20% LiClO4 at 80°C was 1.8 × 10−4 s•cm−1. IWPUS based on ionic liquid‐based waterborne polyurethane would be promised to become an environmentally friendly candidate for all solid‐state lithium ion batteries.

In this study, thermoplastic polyurethane (TPU) with 30%wt hard segment content (HSC) was synthesized using isophorone diisocyanate (IPDI), 1, 4-butanediol (BDO) as the chain extender, and polycaprolactone (PCL) with three different molecular weights (2000, 4000, and 10000) as polyols. Fourier-transform infrared spectroscopy (FTIR), hydrogen nuclear magnetic resonance (H-NMR), X-ray diffraction (XRD), and differential scanning calorimetry (DSC) analysis were used to evaluate the chemical microstructure and physical characteristics of polycaprolactones (PCLs) and thermoplastic polyurethanes (TPUs). The results showed that the crystallinity and the glass transition temperature (Tg) of TPUs became different depending on the molecular weight of the PCL soft segments. A tensile strength was used to evaluate the mechanical properties of TPUs. It was observed that increasing the molecular weight of PCL decreased the elongation at break and increased the ultimate tensile strength. The permeability of CO 2 and N 2 gase over wide ranges of pressure (3 to 9 atm) was examined, and the permselectivity of the membranes was determined. It was concluded that an increase in the feeding gas pressure led to an increase in the gas permeability of all samples. It was observed that in TPU samples, the increase in the molecular weight of PCLs led to a decrement in selectivity and an increase in permeability of CO 2 and N 2 gas.
