“…Polymer matrices can absorb a large amount of liquid electrolyte solution to form gel polymer electrolytes (GPEs). GPEs exhibit high ionic conductivity, good interface stability, and a long service life [ 5 , 6 , 7 , 8 , 9 ]. In particular, poly (methyl methacrylate) (PMMA)-based electrolyte is regarded as a promising material because PMMA has good chemical stability, is a low-cost raw material, and can reduce the interfacial resistance between the polymer electrolyte and the electrodes [ 10 , 11 , 12 , 13 , 14 , 15 , 16 ].…”

Gel polymer electrolyte (GPE) is widely considered as a promising safe lithium-ion battery material compared to conventional organic liquid electrolyte, which is linked to a greater risk of corrosive liquid leakage, spontaneous combustion, and explosion. GPE contains polymers, lithium salts, and liquid electrolyte, and inorganic nanoparticles are often used as fillers to improve electrochemical performance. However, such composite polymer electrolytes are usually prepared by means of blending, which can impact on the compatibility between the polymer and filler. In this study, the hybrid copolymer poly (organic palygorskite-co-methyl methacrylate) (poly(OPal-MMA)) is synthesized using organic palygorskite (OPal) and MMA as raw materials. The poly(OPal-MMA) gel electrolyte exhibits an ionic conductivity of 2.94 × 10−3 S/cm at 30 °C. The Li/poly(OPal-MMA) electrolyte/LiFePO4 cell shows a wide electrochemical window (approximately 4.7 V), high discharge capacity (146.36 mAh/g), and a low capacity-decay rate (0.02%/cycle).

“…LEs are volatile and may leak [24,25]. This will cause the electrode to corrode and the dye to decompose in the medium [26,27]. On top of these, sealing and stability problems are also associated with LEs [28,29].…”

Ionic liquids (ILs) are molten salts at ambient temperature and consist of poorly coordinating cations and anions. They have good electrical conductivity with a wide voltage window and high thermal stability, but negligible vapor pressure. ILs can enhance ionic conductivity when added to polymer electrolytes. Conductivity enhancement is due to the additional ions supplied by the IL, the plasticizing nature of the IL and the low viscosity that facilitates ion mobility. The plasticizing nature of ILs softens the polymer chain giving rise to easier polymer segmental motion. Increase in polymer segmental motion implies that IL can increase amorphousness of a polymer electrolyte (PE). This article discusses the involvement of ionic liquid as electrolytes in selected devices, namely dye sensitized photovoltaics, batteries, fuel cells and supercapacitors.

“…However, a trade-off is the reduction of the conversion efficiency. To make the quasi-solid electrolytes some polymers are usually used such as polyacrylonitrile (PAN) [9], polymethylmethacrylate (PMMA) [10], and polyvinylidenefluorideco-hexafluoropropylene (PVDF-HFP) [11]. Among them, PMMA possesses many desirable properties such as light weight, high transparency, chemical resistance, resistance to corrosion, and high melting point.…”

A quasi-solid electrolyte dye-sensitized solar cell (QSDSSC) was fabricated, which used an environment-friendly organic MK2 dye. The quasi-solid electrolyte was fabricated based on I -/I3redox couple and polymethylmethacrylate (PMMA) polymer. Ozone treatment technique has been utilized to clean and improve the hydrophilicity of TiO � thin films, as a result, its dye-adsorption capacity was enhanced. Experimental results with a solar simulator showed that 40 % improvement of the conversion efficiency was obtained with the QSDSSCs fabricated with the photoanodes undergone the ozone treatment compared with the QSDSSCs fabricated with the photoanodes without the ozone treatment. Furthermore, we also conducted a stability test on the QSDSSCs fabricated with the ozone-treated photoanodes to study the stability of the organic MK2 dye and the PMMA-based gel electrolyte.
