A Superionic Conductive, Electrochemically Stable Dual-Salt
It showed that ionic conductivity of SPE reached the highest values at the ratio of 25:40:35 (crosslinked PEGDA/plasticizer/lithium salt) and 35:35:30. The highest average ionic conductivities were 0.76 mS/cm (25:40:35) and 0.62 mS/cm (35:35:30) at 20°C.
A Superionic Conductive, Electrochemically Stable Dual-Salt
The dual-salt polymer electrolyte-based cells exhibited excellent average coulombic efficiency of 99.99% in the first 370 cycles. The initial capacity at 30°C is 138 mAh/g (0.2 C), which is close to the value achieved by liquid-electrolyte-based cells under similar condition.
Electrochemically Stable Carbazole-Derived Polyaniline
Supercapacitor energy storage devices are well suited to meet the rigorous demands of future portable consumer electronics (PCEs) due to their high energy and power densities (i.e., longer battery-life and rapid charging, respectively) and superior operational lifetimes (10 times greater than lithium-ion batteries). To date, research efforts have been narrowly focused on improving the specific
An acrylate-based quasi-solid polymer electrolyte
Thermal analysis revealed high stability with an extrapolated onset temperature of 263 °C (weight loss as the cause of evaporation of bCN-PEG4) and a decreased T g of 55.7 °C. bCN-SPE55% is electrochemically stable up to 5 V vs. Li/Li +, which allows the application as a polymer electrolyte in high-voltage electrochemical storage systems.
Electrode material–ionic liquid coupling for electrochemical
The advantageous electrochemical stability of ILs does not always yield a wider electrochemical stability window (ESW) and greater energy density in an EES device because of irreversible...
