Review on the recent progress in the nanocomposite polymer electrolytes on the performance of lithium‐ion batteries

Abstract

Summary In the recent decade, lithium‐ion batteries have flourished in the mobile market to a greater extent. Despite its versatile commercial applications in various fields, it faces critical issues that restrict by safety concerns including leakage, combusting, or even explosions because of the low boiling point of liquid organic electrolytes. In order to mitigate these difficulties, solid electrolytes can be a potential choice. Polymer‐based solid Li‐ion batteries have been attracting researchers for accomplishing high performance. However, poor mechanical strength and low transport of Li+ ions inside the cell remain prominent challenges for its commercialization. To solve these issues and enhance the overall performance, polymer‐based nanocomposite electrolytes developed by incorporating the nanofillers into the polymer matrix have been investigated to a greater extent. This review briefly elaborates on the recent progress of polymer nanocomposite electrolytes for lithium‐ion batteries, factors affecting its performance, and various models used in the interpretation of its performance.

All‐Inorganic Micrometric CsPbBr3:Yb3+ Powder as a Multifunctional Material for Photovoltaics and Optical Thermometry: Structural and Optical Characterization

“…Fundamental parameters of the solar cell with CsPbBr 3 :Yb 3+ perovskite layer were determined from the fitting of its “light” I – V characteristics with a well‐known double‐diode model (DDM). [ 61 ] For comparison, two reference samples were also analyzed: one—without the perovskite layer, which was a commercial monocrystalline Si solar cell, and the other—a device with pure CsPbBr 3 layer. The “light” I – V curves fitted with DDM for all the aforementioned solar cells are shown in Figure .…”

“…Current–voltage ( I – V ) characteristics of the studied solar cells were measured at 25 °C using the I – V curve tracer equipped with the PET Solar Simulator (#SS100AAA) operating at light intensity of 1000 Wm −2 (i.e., 1‐sun illumination, AM1.5G). The measured, illuminated I – V curves were fitted by the IV Curve Fitter v1.8 Copyright ‘2002 software [ 63 ] that uses double‐diode model [ 61 ] to extract fundamental parameters of solar cells, such as: open circuit voltage, short‐circuit current, fill factor, efficiency, etc. The external quantum efficiency (EQE) and spectral response of the solar cells were measured with a Bentham PVE300 system calibrated by a certified reference Si photodetector, using a xenon–quartz tungsten halogen dual lamp.…”
