“…[185][186][187] Generally speaking, macromolecules like polysiloxane [188][189][190][191][192] and POSS [193][194][195][196][197][198][199][200][201] always serve as the key constituents, while micromolecules like siloxanes usually act as crosslinkers in solid electrolytes. [202] In some cases, these organosilicon polymers can be copolymerized with other polymer chain segments like PMMA [203] and poly (ethylene glycol) (PEG), [204] or modified with ILs, [71] and sometimes filled with nanoparticles [205] to improve the overall performances.…”

Nowadays excessive consumption of fossil fuels due to population growth and industrial development induced serious energy and environmental crisis. To alleviate the ecological crisis and comply with the ever-increasing energy demand, developingThe electrolyte has been considered as a key factor toward higher energy density for Li-ion and Li-metal batteries. However, conventional electrolytes suffer from uncontrolled interfacial reactions and irreversible decomposition causing performance deterioration and potential safety hazard. Organosilicon compounds have attracted great interest as promising electrolyte components due to facile chemical modifications, low glass transition temperatures (T g ), superior chemical, and thermal stabilities. Considerable investigation efforts have been devoted to developing better overall performance of organosilicon-based electrolytes in the past few years. Herein, the recent research progress of organosilicon-based functional electrolytes for the development of liquid, gel, and solid state electrolytes in Li-ion and Li-metal batteries is summarized. Attention is devoted to various types of organosilicon such as silane, siloxane, polysiloxane, and polyhedral oligomeric silsesquioxanes in terms of molecular design, ionic conductivity, functions shown in batteries, thermal, chemical, electrochemical stability, safety, etc. The feasible strategies are also discussed that may promote the comprehensive electrochemical performances of organosilicon-based electrolytes in different types of electrolytes and batteries. Finally, the challenges facing organosilicon-based electrolytes and proposed their possible solutions are presented alongside promising development directions.

“…Additionally, it was difficult to acquire a complete and uniform fiber structure when continuing to increase the weight ratio of SPI to PVA via the electrospinning technology because of the inherent brittleness and entanglement structure of SPI molecular chains. Meanwhile, with the addition of SPI content, the porosity of nanofiber membranes increased from 80% for pure PVA sample to 89% for SPI/PVA (3:1) composite nanofiber membranes, as shown in Table 1, which was much higher than that of membranes prepared by solution casting, 6,18,19 and phase inversion. 20 The high porosity and interconnected nanoporous structure in these nanofiber membranes was favor to enhance adsorption capacity of liquid electrolyte, and expand ionic transport channel.…”

A kind of biodegradable and well-sourced soy protein isolate (SPI)/poly(vinyl alcohol) (PVA) composite nanofiber membranes was fabricated via electrospinning and used as skeleton material in gel polymer electrolyte (GPE) of lithium-ion batteries. This study revealed that the proper material proportion, low crystallinity, sufficient porosity and good affinity between nanofiber and the electrode/electrolyte resulted in high saturated electrolyte uptake and conservation rate of the nanofiber membranes. The GPEs based on the SPI/PVA composite nanofiber membranes presented remarkable electrochemical performance, including high ionic conductivity, excellent compatibility with lithium electrode and good electrochemical stability. An ionic conductivity of 3.8 × 10–3 S cm–1 and interfacial resistance of 250 Ω for the GPEs can be obtained when the weight ratio of SPI to PVA in the spinning solution was 3:1, which was more superior to the existing biobased GPEs. In addition, the Li/GPE/LiCoO2 cells with GPEs based on the SPI/PVA (3:1) composite nanofiber membranes displayed the excellent initial discharge capacity and cycle performance. Therefore, the environmental and economical SPI/PVA composite nanofiber membranes with the optimized material proportion can be used as a green skeleton material in GPEs for high performance lithium-ion batteries.

The critical challenges for lithium-ion batteries today are how to improve the energy densities and solve the safety issues, which can be addressed through the construction of solid-state lithium metal batteries with solid polymer electrolytes (SPEs). Significant efforts have been devoted to the design and synthesis of SPEs, in which their electrochemical windows and corresponding compatibilities with both electrodes are crucial, particularly when taking high-voltage transition metal oxides as cathodes. In this review, the SPEs with different electrochemical windows are summarized and categorized, including (i) anode stable SPEs with good lithium metal compatibilities, (ii) cathode stable SPEs with good oxidation resistances, (iii) multilayer SPEs simultaneously withstanding reduction of a lithium anode and oxidation at high voltage. The impacts of polymer molecular structures and compositions on the SPE properties and performance are discussed. The development of high-performance SPEs that can stabilize or form stable interfacial passivation layers with both cathodes and anodes simultaneously is the desired candidate of future applications.
