Abstract:

To eliminate electrolyte leakage, the development of safe and flexible supercapacitors necessitates solid-state electrolytes which integrate both high mechanical and electrochemical capabilities. Quasi-solid-state electrolytes, which constitute a polymer matrix along with an aqueous electrolytic phase, are a viable answer to this problem. Recently, gel electrolytes have gained a lot of attention in flexible and wearable electronic devices due to their remarkable advancements. However, the limitation in the multi-functional abilities and high-performance in such gels hinders the practical usage

Abstract:

Despite intense research in the field of aqueous organic redox flow batteries, low molecular stability of electroactive compounds limits further commercialization. Additionally, currently used methods typically cannot differentiate between individual capacity fade mechanisms, such as degradation of electroactive compound and its cross-over through the membrane.

Abstract:

What factors affect the electrochemical stability window of aqueous electrolytes? The primary challenges of aqueous electrolytes are water’s electrolytic reactions, namely hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). These parasitic reactions shorten the cycle life of batteries, limit the energy density of batteries, and cause safety concerns. There are generally two approaches to mitigate water’s electrolytic reactions: thermodynamic and kinetic. The thermodynamic route involves manipulating the chemical environment of water molecules in the bulk electrolyte so that

Abstract:

Lithium-ion (Li-ion) batteries have become an important solution for energy storage owing to their high gravimetric and volumetric energy density. The electrolyte solution of the battery has a large effect on the stability and performance of the cell. During the first cycles of a battery, the solid electrolyte interphase (SEI) layer is formed due to the degradation of the electrolyte. Hence the composition of this layer, and the stability, are dependent on the electrolyte composition. The most commonly used electrolyte for Li-ion batteries is the salt lithium hexafluorophosphate LiPF6 dissolve

Abstract:

Solid-state batteries (SSBs) have been widely studied as next-generation lithium-ion batteries (LiBs) for many electronic devices due to their high energy density, stability, nonflammability, and chemical stability compared to LiBs which consist of liquid electrolytes. However, solid electrolytes exhibit poor electrochemical characteristics due to their interfacial properties, and the sintering process, which necessitates high temperatures, is an obstacle to the commercialization of SSBs. Hence, the aim of this study was to improve the interfacial properties of the lithium tantalum phosphate (

Abstract:

Solid state batteries show advantages in battery safety, energy density and temperature tolerance and therefore are considered promising alternative of Li-ion batteries using organic electrolytic solutions. Solid electrolytes are critical components in solid-state batteries. Among different types of solid electrolyte, oxide based, garnet-type Li7La3Zr2O12 (LLZO) solid electrolytes have been of particular interest due to the combination of good ionic conductivity and chemical stability against metallic lithium. However, these materials exhibit surface degradation when exposed to air and moistur

Abstract:

Lithium-ion batteries often see dramatic capacity losses when cycling at low temperatures, due to sluggish lithium transport within the bulk electrolyte and at the electrode-electrolyte interfaces. The development of new battery electrolytes with enhanced lithium-ion conductivity and improved interfacial transfer at low temperatures is needed to improve the overall stability and wide operating range performance of batteries. Koura has developed fluorinated materials for lithium-ion electrolytes with improved stability and safety properties, and in this study their efficacy in batteries under l

All-solid-state lithium-ion batteries based on solid electrolytes are attractive for electric applications due to their potential high energy density and safety. The sulfide solid electrolyte (e.g., argyrodite) shows a high ionic conductivity (10−3 S cm−1). There is an open question related to the sulfide electrode’s fabrication by simply infiltrating methods applied for conventional lithium-ion battery electrodes via homogeneous solid electrolyte solutions, the structure of electrolytes after drying, chemical stability of binders and electrolyte, the surface morphology of electrolyte, and the

To overcome the risk of electrolyte leakage and the shortcoming of higher impedance at high frequencies for the conventional aluminum electrolytic capacitor impregnated with electrolyte solutions, solid aluminum electrolytic capacitor employing conducting polyaniline (PANI) as a counter electrode was developed. The as-fabricated solid capacitors have very low impedances at high frequencies and excellent thermal stability. The superior performances can be ascribed to high conductivity and good thermal stability of the camphorsulfonic acid (CSA)-dodecylbenzenesulfonic acid (DBSA) co-doped PANI.
