“…Polyethylene terephthalate (PET) has been widely used in daily life, especially in the field of food packaging for its good barrier properties and stability. [1][2][3] With the rapid development of the packaging industry, discarded PET bottles have been increasing year by year. Being difficult to degrade naturally, they not only cause environmental pollution but also a waste of resources.…”

“…The development of electronic devices and the utilization of various renewable energies have created an urgent demand for advanced energy storage devices (Huang et al, 2020;Yuan et al, 2021;Lu et al, 2021). Electric double-layer capacitors (EDLCs) (Zhang et al, 2018), also known as super capacitors, have received much attention in recent years due to their high power density and extremely long shelf-life.…”

A modified ionic liquid (IL)-based electrolyte, with conventional carbonates as the support solvent and lithium salt as the additive, was designed for a high-voltage electrochemical double-layer capacitor (EDLC). It is found that the employment of carbonate solvents enhances the ionic conductivity and decreases the viscosity of the electrolyte. At the same time, the addition of lithium salt plays a key role in the stabilization of the operating potential window and the modification of the passivation layer on the electrode. As a result, increased specific capacitance, improved cycle stability, and rate capability are demonstrated in the EDLC with an EMI-BF4/LiPF6/PC/DMC electrolyte at the upper voltage of 3 V, in contrast to that with pure IL and IL/carbonate mixture. This study primarily stresses the combination effect of Li salt and organic solvent in an IL electrolyte system for constructing advanced 3 V-class EDLC with excellent overall performance.

“…[7][8][9] Once it exceeds the critical point, the permittivity decreases and the dielectric loss increases rapidly accompanied by weakened mechanical strength. 2,10,11 Therefore, exploring or modifying dielectric material with stable dielectric properties, high energy storage density (W rec ) and electro-mechanical stability, etc. under potential operation conditions is one of the most important directions.…”

Perovskite solid solutions of SrTi(Cu 1/3 Nb 2/3 )O 3 (STCN) modified 0.8Bi 0.5 Na 0.5 TiO 3 −0.2Bi 0.5 K 0.5 TiO 3 (BNT-BKT) in the vicinity of morphotropic phase boundary composition were prepared. The dielectric and impedance properties associated with their structural evolution were investigated. Strong unsteadiness and large hysteresis (dielectric loss) under elevated temperature and variational frequency restrict the development of BNT-BKT based ceramics. Here we show a distinct phase transition from ferroelectric to ergodic relaxor phase that occurs with increasing STCN. Incremental chemical defects resulted from the substitution of the A/B site facilitate the distributions of polar nanoregions. The flatter and smoother dielectric curves between T s and T m illustrate good temperature stability. The complex impedance spectrums demonstrate that the compositions possess a mixed electronic and ionic conduction mechanism. More oxygen vacancies can be introduced into the lattice, contributing to a decremental impedance as the increased dopant. Meanwhile, Nb Ti• will suppress p-type conduction and reduce dielectric loss. Favorable stabilities of dielectric permittivity, energy storage, and electrostrictive strain were achieved, attributed to the existence of nanodomains.
