Abstract

A novel N-methylphenothiazine based ionic liquid (NMP-IL) was designed for achieving low-driving voltage electrochromic device (ECD) with thermal durability. NMP-IL was synthesized via a five-step reaction, including thionation, methylation, substitution, ionization, and anion exchange. By chemically bonding with the ionic liquid, NMP-IL exhibited a large optical contrast and high thermal stability simply to take the advantages of both NMP and ionic liquid features. Compared to NMP, NMP-IL would provide the electrolyte with a higher ionic conductivity, thus reducing the driving voltage of the ECDs. Most importantly, an extremely low-driving voltage (0.6 V) ECD based on NMP-IL and nickel hexacyanoferrate (NiHCF) thin film, known as the ion storage layer, was further demonstrated. The proposed NMP-IL/NiHCF ECD accomplished a large transmittance change of 56.6% at 575 nm, a desirable coloration efficiency of 166 cm2/C, and attenuated 120.9 W/m2 solar irradiance between bleached state and colored state with a minimal consumed power per unit area of 1.08 W/m2. Besides, impressive long-term stabilities of the proposed ECDs, under both room temperature (92.3% retention of its original ΔT after 10,000 cycles) and high temperature (80.2% retention of its original ΔT after 3,000 cycles at 65 °C), were achieved. These merits reveal that NMP-IL has the potential to become the new anodically coloring material for application in energy-saving ECDs.

Abstract

It is extremely challenging to achieve a high-volumetric-energy–density lithium-sulfur batteries (LSBs) for sulfur/carbon cathodes due to their low volumetric density and many invalid pores. Herein, such a dense sulfur monolith cathode with a high volumetric energy density of 2067 Wh L−1 and a large volumetric capacity of 980 mAh cm−3 (of the total volume of cathode) is demonstrated, where sulfur/TiO2 quantum dots (QDs, ~3.6 nm) are anchored on nitrogen-rich graphene (S/TiO2-QDs/N-G) and sulfur cathode is densified to a volumetric density of 1.6 g cm−3 with a conductivity of ~270 S m−1 by drying the graphene hybrid hydrogel. Such high-volumetric capacity is one of the best value in all reported sulfur/carbon cathodes. Besides, the monolith cathode gives a superior long-term cycling stability with only 0.06% capacity decay per cycle for 500 cycles at 0.5 A g−1. More importantly, under a low electrolyte/sulfur ratio of 4.2 μL mg−1, the thick and dense monolith cathode with sulfur loading of 5.5 mg cm−2 displays an areal capacity of 4.92 mAh cm−2 at 0.1 A g−1. Furthermore, the size effect of TiO2-QDs (anchored on N-G) on electrochemical performances of LSBs and its adsorption mechanism for polysulfides demonstrate the significantly enhancement in discharge capacity and cycling stability of dense monolith cathode derives from the strong capture ability of ultra-small-sized TiO2-QDs for polysulfides. The highly dense sulfur cathode with ultra-small sized sulfur immobilizers (e.g. metal oxides, sulfides, or phosphides) provides a new strategy for designing high-volumetric-energy–density LSBs with superior long-term cycling stability even in lean electrolyte condition.
