Inorganic Fillers in Composite Gel Polymer Electrolytes for High-Performance Lithium and Non-Lithium Polymer Batteries

Abstract

Among the various types of polymer electrolytes, gel polymer electrolytes have been considered as promising electrolytes for high-performance lithium and non-lithium batteries. The introduction of inorganic fillers into the polymer-salt system of gel polymer electrolytes has emerged as an effective strategy to achieve high ionic conductivity and excellent interfacial contact with the electrode. In this review, the detailed roles of inorganic fillers in composite gel polymer electrolytes are presented based on their physical and electrochemical properties in lithium and non-lithium polymer batteries. First, we summarize the historical developments of gel polymer electrolytes. Then, a list of detailed fillers applied in gel polymer electrolytes is presented. Possible mechanisms of conductivity enhancement by the addition of inorganic fillers are discussed for each inorganic filler. Subsequently, inorganic filler/polymer composite electrolytes studied for use in various battery systems, including Li-, Na-, Mg-, and Zn-ion batteries, are discussed. Finally, the future perspectives and requirements of the current composite gel polymer electrolyte technologies are highlighted.

Designing Versatile Polymers for Lithium-Ion Battery Applications: A Review

“…However, ionic conductivity improvements by adding Al 2 O 3 particles into a PEO-based matrix were first proposed by Wieczorek et al [ 22 ] in 1989. Since then, the incorporation of a wide range of inorganic inactive fillers into polymer electrolyte matrices have been extensively studied [ 134 , 135 , 136 , 137 , 138 ].…”

Electrochemical Cells and Storage Technologies to Increase Renewable Energy Share in Cold Climate Conditions—A Critical Assessment

“…This will make them less dangerous and suitable for high-current applications with high discharge rates [24]. As a result, polymer gel electrolytes have potential for high-performance lithium and non-lithium batteries [99].…”

“…Additionally, an Li-Po battery has the same morphology as any rechargeable battery (Figure 19) [99]. Other approaches have been developed to evaluate the characteristics of Li-ion batteries operating in very cold climate conditions.…”

“…27 Also, various inorganic ller were also reported, such as titania (TiO 2 ), zircronia (ZrO 2 ), carbon-nanotubes (CNT), graphene (Gr) and silica (SiO 2 ). [28][29][30][31][32] In spite of these substantial amounts of research works PEs, their application in DSSCs is still limited. The advantage of coordinating polymer and an appropriate salt in the solid-state have been used by researchers.…”
