Summary: Polyvinyl alcohol (PVA) polymer was mixed with different weight ratios of 1-ethyl-3methyltricynomethanide (EMIm-TCM) to develop solid polymer electrolytes (SPEs). Introducing ionic liquid (IL) into PVA's structure improved its mechanical properties, flexibility, and conductivity, increasing its potential in energy devices. The maximal ionic conductivity of 3.85 x 10-4 Scm �1 was achieved by adding 30 wt% IL. Structural and morphology analysis showed enhanced amorphous nature and the FT-IR spectrum confirmed perfect complexation.

Summary: In recent years, electrochemical capacitors operating in an aqueous electrolyte solution have gained popularity due to their low cost and eco-friendliness. Aqueous electrolytes have higher ionic conductivity compared to organic electrolytes and ionic liquids. This study focuses on hydrogel polymer electrolytes (HPEs) obtained through photopolymerization of a mixture of acrylic oligomer Exothane 108 and methacrylic acid in ethanol. The HPEs showed promising properties such as high ionic conductivity and mechanical stability, making them suitable for application in AC/AC electrochemical double layer capacitors (EDLC).

Summary: Nowadays, solid polymer electrolytes, especially gel polymer electrolytes (GPEs), have gained increasing attention for their wide electrochemical stability window, low cost, excellent processability, flexibility, high ionic conductivity, and solid-like dimensional stability. GPEs show promise for applications in various electrochemical devices such as rechargeable batteries, supercapacitors, electrochromic displays, sensors, and actuators. This study aims to demonstrate the viability of a sustainable GPE that can replace aqueous electrolytes in low voltage electrochemical devices. A polyvinyl alcohol (PVA)-based GPE has been successfully prepared using a simplified preparation route without organic solvents or ionic liquids.

Summary: Solid polymer electrolytes (SPEs) are the best choice to replace liquid electrolytes in various energy storage devices, but their ionic conductivity and thermal stability still need to be improved. In this study, PVA/salt based SPEs were fabricated using different methods and the effect of different salts and their concentrations on the ionic conductivity was investigated. The results showed that the addition of NaCl, KCl and KI salts significantly increased the ionic conductivity, and electro-spun NaCl SPEs exhibited higher conductivity compared to casted SPEs.

Summary: The application of water-based supercapacitors is limited by electrolyte leakage and corrosion. This study presents a quasi-solid-state supercapacitor based on carbon felt electrode and PVA-KI/H2SO4 mixed gel electrolyte, and reports a stable uniform acetalized polyvinyl alcohol (UAPVA) membrane under acidic conditions. The UAPVA membrane, with excellent chemical and mechanical properties, facilitates ion transportation and retains its shape after stretching, bending, and twisting, making it suitable for flexible quasi-solid-state devices. The device exhibits outstanding electrochemical performance and good mechanical flexibility and stability. Moreover, the addition of redox agents to traditional electrolyte solutions is found to be effective for high-performance energy storage devices.

Summary: Solid polymer electrolytes (SPEs) are a promising avenue for flexible lithium-ion batteries. However, the low ionic conductivity of polymers remains a challenge. In this study, SPE/FGO electrolytes were prepared using PEO, polyvinyl alcohol, LiClO4, and graphene functionalized with polyethylene glycol. The presence of functionalized graphene effectively reduced crystallinity, and the samples exhibited adequate ionic conductivity at room temperature.

Summary: This study developed a mechano-electrochemical model to investigate the electrochemical performance of solid-state Li metal batteries under bending deformation. It was found that bending alters ion transport and electric potential in the electrolyte, depending on the bending direction. Although the direct influence of bending on electrochemical kinetics is limited, it can increase stress and potential mechanical failure, leading to degradation of electrochemical performance.

Summary: This study attempts to incorporate organic nanofillers (carbon dots derived from glucose) into a polymer blend PVA-PEG/NaCl to investigate their effects on the physico-chemical properties, ionic conductivity, and ion transport mechanism. The addition of organic nanofillers significantly enhances the room temperature ionic conductivity and electrochemical stability of the blend polymer. The flexible membranes based on PVA-PEG/NaCl/g-CDs have not been reported before and show great potential as solid polymer electrolytes.
