“…In 1999, Capiglia and co-workers prepared the nanocomposite-based PE by embedding nanosized silica (SiO 2 ) into the PEO-LiClO 4 polymer electrolytes [57]. Another literature also showed that the nanosized aluminium oxide (Al 2 O 3 ) improved the ionic conductivities of PEs [141]. In a study conducted by Madhurjya et al, the mechanical strength of a hydrotalcite-doped nanocomposite PEs was improved [142].…”

“…One of the major drawbacks of the liquid electrolytes is the leakage of hazardous liquid or gas. In recent years, solid polymer electrolyte systems have become a prominent material used in the development of various batteries [141]. They offer many advantages in the battery applications such as low manufacturing cost, low toxicity, good structural and chemical stability and possess dual function as an electrolyte and a separator as well [205].…”

In this paper, we review different types of polymer electrolytes, recent approaches and technological applications of polymer electrolytes. The report first discusses the characteristics, advantages and applications for three types of polymer electrolytes: gel polymer electrolytes, solid polymer electrolytes and composite polymer electrolytes. Next, we discuss the features and performance of different polymer hosts based on some important and recently published literature. Recent progress of some approaches used in improving the performance of the polymer electrolytes is highlighted. The last part of the review includes the technological applications of some electrical energy storing/converting devices: electrochemical capacitors, batteries, fuel cells and dye-sensitized solar cells. It is also stressed that the technological advancement in the polymer electrolytes plays a pivotal role in the development of energy storing/converting systems.

The development of solid composite electrolytes or solid composite electrolytes (SCEs) consisting of an ionic conductor and a dielectric matrix offers an elegant strategy to enhance the ionic conductivity of electrolytes by engineering the interface conduction. At the conductor/matrix interface, the ionic conductivity can be enhanced by the enriched charge carrier concentration and/or the changed molecular structure of the ionic conductor. This review deals with the interfacial ion conduction mechanisms of the inorganic particle‐based SCE, polymer‐SCE, and ionic liquid electrolyte‐based SCE (ILE‐SCE). In the first part of this review, an overview is given of the space‐charge theory developed to describe the increased vacancy concentration at the interface of inorganic particle‐based SCE. In the second part, the proposed interface interactions and structural changes associated with interface conduction for the polymer‐SCE and ILE‐SCE are reviewed. For the ILE‐SCE, the preparation methods and interface characterization are discussed together with the proposed conductivity models. The use of mesoporous matrix materials with high internal surface area for ILE‐SCE is reviewed here for the first time.

“…However, due to the absence of exact structure-property correlations in the polymer electrolyte systems, a complete understanding of the ion conduction phenomenon is still lacking. Nonetheless, to explain the mechanistic aspects of ion transport in micro/nanocomposite polymer electrolyte systems, a working hypothesis has been suggested accordingly to which, the dispersion of submicron or nano-size filler particles having large surface area, into the polymer host lowers the degree of crystallinity, which may also be thought to be due to Lewis acid-base interaction between ceramic surface states and polymer segments (Croce et al, 1998;Golodnitsky et al, 2002). Hence, in addition to the usual space charge effects of the dispersoid particles, the increased amorphosity would also support the conductivity enhancement in terms of increased ionic mobility through the amorphous phase.…”
