Supercapacitor Applications

In this study chitosan/poly(ethylene glycol)-ran-poly(propylene glycol) blend was developed as separator and binder for supercapacitor (SC) applications. The activated carbon (ACTS-900) derived fromTamarindus indicaseeds is used as active electrode material.

With a higher theoretical specific capacity (1675 mAh g−1) and energy density (2600 Wh kg−1), the lithium-sulfur (Li-S) battery is considered as a promising candidate for a next-generation energy storage device. However, the shuttle effect of polysulfides as well as the large interfacial impedance between brittle solid electrolyte and electrodes lead to the capacity of the Li-S battery decaying rapidly, which limits the practical commercial applications of the Li-S battery. Herein, we reported a facile in situ ultraviolet (UV) curing method to prepare a flexible quasi-solid-state composite electrolyte (QSSCE) of poly(propylene glycol)-co-pentaerythritol triacrylate/Li1.5Al0.5Ge1.5(PO4)3 (PPG-co-PETA/LAGP). By combining the high Li-ion conductivity and mechanical strength of inorganic NASICON-structure LAGP and good flexibility of the crosslinked PPG-co-PETA with nanopore structure, the flexible QSSCE with 66.85 wt% LAGP exhibited high Li-ion conductivity of 5.95 × 10−3 S cm−1 at 25 °C, Li-ion transference number of 0.83 and wide electrochemical window of ~5.0 V (vs. Li/Li+). In addition, the application of QSSCE in the Li-S battery could suppress the shuttle effect of polysulfides effectively, thus the Li-S battery possessed the excellent electrochemical cyclic performance, showing the first-cycle discharge-specific capacity of 1508.1 mAh g−1, the capacity retention of 73.6% after 200 cycles with 0.25 C at 25 °C and good rate performance.

Abstract The temperature dependence of the ionic conductivity in the PPG-rich part of the ternary system poly(propylene glycol)-poly(methyl methacrylate)-LiCF3SO3 has been investigated. The highest conductivity values, 3 x 10-5 (ohm cm)-1 at 31 °C and 4 × 10-4 (ohm cm)-1 at 77 C, were obtained for samples which had the properties of a pressure sensitive adhesive. The temperature dependence of the ionic conductivity could be well described by the Vogel-Tammann-Fulcher equation.
