“…In addition, because the electrolyte membrane is dry, the hydroxyl peak cannot come from water, and the hydroxyl peak at 1194 cm –1 can prove that it was present on the electrolyte. TFSI – peaks appeared at 740, 1135, and 1335 cm –1 . , Furthermore, the characteristic peaks at 1060 and 786 cm –1 belong to the symmetrical vibrations of the Si–O–Si bond caused by the polymerization reaction of PPO. The changes of these peaks indicate that cross-linking reactions occurred in the oligomeric PPO and formed long chains.…”

The optimized combination of the organic/inorganic components in a composite solid electrolyte (CSE) plays a crucial role in improving its ion conductivity and thermal-mechanical performances. In this work, a high-filled Li7La3Zr2O12 (LLZO)/polypropylene oxide (PPO) CSE film was prepared by introducing LLZO microparticles in a flexible PPO polymer electrolyte. As the content of LLZO increases, the lithium-ion migration pattern is changed from migrating with the PPO chain segment movement to along the continuous fast ion conducting networks formed by the high-filled LLZO particles. When the LLZO content reaches 45 wt %, the room-temperature ion conductivity is up to 3.79 × 10–4 S cm–1, and the potential window is about 5 V. Meanwhile, the addition of LLZO particles enhances the mechanical and thermal properties of the PPO electrolyte, the maximum tensile strength reaches 56.41 Mpa, and the temperature resistance reaches above 200 °C. This CSE film with improved ion transport and safety performances shows high practical significance in the development of solid-state lithium batteries.

High ionic conductivity, excellent mechanical and thermal properties, and good inhibiting ability for lithium dendrites are essential requirements for polymer solid electrolytes (SEs). In this work, a flexible polypropylene oxide-based SE film was prepared by combining the bis[3-(methyldimethoxysilyl)]-terminated polypropylene oxide (BSPPO) high polymer with ZrO 2 fillers, the succinonitrile (SN) plasticizer, and the cellulose membrane framework. The cross-linking reaction of the BSPPO oligomer initiated by lithium bis(oxalate)borate at the addition of SN and ZrO 2 improves the ionic conductivity of the prepared SE as high as 9.619 × 10 −4 S cm −1 at room temperature with a high ion migration number of 0.8 and a high potential window of 5 V. The excellent mechanical strength, thermal stability, and good lithium dendrite inhibition ability greatly enhance the safety of the electrolyte in the use of lithium batteries. The assembled NCM622/SE/Li solid-state batteries can be stably cycled at a current density of 0.1−1 C. This safety-enhanced rigid-flexible BSPPO−ZrO 2 composite SE film with high ionic conductivity is expected to be widely used in high-performance solid-state lithium batteries.

“…Although vinyl ether monomers do not homopolymerize to produce high molecular polymers via free‐radical polymerization, they have been shown to undergo free‐radical copolymerization with electron deficient, vinyl‐functional monomers due to the formation of charge‐transfer complexes. Electron deficient comonomers that have been successfully copolymerized with vinyl ethers using free radical polymerization include maleic anhydride , citraconic anhydride , maleonitrile , vinylidene cyanide , alkyl α‐cyanoacrylate , and maleimides . Copolymerization of any of these monomers with 2‐VOES would provide an increase in T g compared to poly(2‐VOES).…”

A plant oil-based polymer technology was recently developed that enables high molecular weight polyvinylether polymers to be produced using cationic polymerization. The plant oil monomer synthesis involves simple base-catalyzed transesterification of a plant oil triglyceride with a hydroxy-functional vinyl, ether such as 4-(vinyloxy)butanol or 2-(vinyloxy)ethanol, to produce a mixture of vinyl ether monomers that possess fatty acid ester groups in their structure. A key aspect of the technology involves the polymerization process that allows for high molecular weight polymers to be produced by polymerization exclusively through the vinyl ether double bonds. This feature enables polymers to be produced that possess unsaturation in the fatty acid ester pendent groups derived from the plant oil starting material. As has been done for conventional plant oil triglycerides, the double bonds can be used to produce thermoset materials either directly through an oxidative process or by derivatization to produce other functional groups, such as epoxides, acrylates, and hydroxyls that can be subsequently used to produce crosslinked networks. The polymerization process also results in a "living" polymerization that allows for control of polymer molecular weight, narrow molecular weight distributions, and the production of unique polymer architectures such as block copolymers. Another very important feature of the technology involves the ability to copolymerize the plant oil-based vinyl ether monomers with other monomers to tailor polymer properties such as glass transition temperature, mechanical properties, and solubility/compatibility with other materials. This document provides an overview of the present state of the technology using soybean oil as a representative plant oil source.
