For high-performance lithium-ion batteries (LIBs), Bi 2 Se 3 /MXene/SWCNT heterostructures emerge as a possible anode choice.
The changes in global energy trends and the high demand for secondary power sources, have led to a renewed interest aqueous lithium-ion batteries. selection of suitable anode media is difficult task because many materials poor cycling performance due side reactions with water or dissolved oxygen. An effective method improving characteristics anodes electrolyte solutions adding carbon nanotubes (CNTs) electrode materials. For better comprehension mechanism accumulation reasons loss capacity...
Abstract The paper reports the results of measurement surface tension in binary liquid mixtures containing choline chloride, ethylene glycol and water ternary ethaline (a eutectic mixture so-called deep solvent) with water. is determined a wide range components’ concentration for temperatures 25, 30, 40, 50, 60 70 °C. dependences on liquids are treated by means Gibbs adsorption isotherm linear form Langmuir isotherms. values equilibrium constant at interface solution/air as well standard...
Due to their layered structure and high theoretical capacity, bismuth chalcogenides have been proposed as anodes in organic electrolyte Li- Na-ion batteries. On the other hand, electrochemical properties aqueous systems not reported. Here, performance of Bi2Se3 thin films 1 M NaNO3 is presented. This system was found up two orders magnitude increased diffusion coefficients, compared anode materials Na electrolyte-based systems, well limited electrode degradation over 5 CVs significant...
In recent years, aqueous rechargeable lithium-ion batteries (ARLIBs) have attracted attention as an alternative technology for electrical storage. One of the perspective battery anode materials application in ARLIBs is Bi2Se3, which has already shown good perspectives conventional (LIBs) that use organic electrolytes. this study, electrochemical properties Bi2Se3 thin films with two different layers on electrode surface—the solid electrolyte interphase (SEI) and Bi2O3 layer—were...
Electrochemical impedance spectroscopy was applied for studying copper oxide (CuO) nanowire networks assembled between metallic microelectrodes by dielectrophoresis. The influence of relative humidity (RH) on electrical characteristics the CuO nanowire-based system assessed measurements Z. A slight increase Z with increasing RH at low followed a three orders magnitude decrease above 50-60%. two opposite trends observed across range examined 5-97% can be caused water chemisorption and...
This study focuses on the surface engineering of binder-free anodes composed Bi, Se, Cu, and carbon nanotubes to enhance lithium-ion batteries. The synthesized in this showed promising electrochemical properties. However, issues with cycle stability, operational speed, solid electrolyte interface (SEI) formation affected their overall performance. To address these challenges, applied different conductive polymers, namely PEO, CMC, PEGDA-co-VC, form artificial SEI layers. application polymers...
Surface activity of sodium dodecylsulfate and micelle formation in solutions based on deep eutectic solvents ethaline reline (eutectic mixtures choline chloride with ethylene glycol urea, respectively) were investigated.The isotherms surface tension treated using Langmuir model the adsorption parameters at interface «solution/ air» determined.The change nature a solvent results decrease equilibrium constant following sequence: water>reline>ethaline>ethylene glycol, which is caused by...

Abstract The main goal of this work is to achieve a direct transfer graphene and examine the exact effect surface tension (ST) on during type transfer. To reach target, we designed specific container with two-sided ports facilitate replacing liquids underneath monitor ST. We prepared various STs by mixing pure deionized-water different ratios isopropanol (IPA). Our results indicate that high ST does not break structure if has good quality. Besides, gap (STG) can be applied at level without...
Adsorption of the components deep eutectic solvent ethaline (ethylene glycol and choline chloride) on mercury electrode is investigated by electrocapillary measurements. It determined that cations are mainly adsorbed negatively charged surface mercury, while chloride anions positively surface. The corresponding values free energies adsorption interactions adsorbate with metal calculated analyzed. An anomalous increase in both apparent value at limiting coverage energy interaction cation...
