Abstract:

We present a mathematical model to study the steady-state performance of a membrane-less reversible redox flow battery formed by two immiscible electrolytes that spontaneously form a liquid-liquid system separated by a well defined interface. The model assumes a two-dimensional battery with two coflowing electrolytes and flat electrodes at the channel walls. In this configuration, the analysis of the far downstream solution indicates that the interface remains stable in all the parameter range covered by this study. To simplify the description of the problem, we use the dilute soluti

Abstract:

Lithium-ion batteries (LIBs) are today the most used energy storage for portable electronics and electric vehicles – but are laden with concerns of materials scarcity and availability. The development of high-voltage cobalt-free cathode active materials such as LiNi0.5Mn1.5O4 (LNMO) represents one promising route for next-generation LIBs due to their combination of high capacity and low cost. Combining LNMO with conventional LIB electrolytes based on carbonate solvents, however, typically leads to severe capacity fading due to a range of different degradation mechanisms1, not the least due to

Abstract:

Interfaces, interphases, and surfaces are of immense interest to the battery research community since the key reactions and much of the kinetics that determine the performance of the cell occur there. While solid/liquid and solid/solid interfaces have been thoroughly studied, liquid/liquid interfaces have attracted much less attention. Here we target the liquid/liquid interfaces between two liquid electrolytes, employed to create dual electrolyte batteries. The grand idea is that based on two either chemically or mechanically immiscible electrolytes we can expand the overall electrochemical st

Abstract:

Systems of two immiscible liquids are proposed for a new type of membraneless fuel cells using renewable fuel, in which the stationary phase boundary carries out a role of membrane. These systems consist of water, alcohol (preferable ethanol) and a number of electrolytes (salts and bases) leading to the layering of aqueous alcohol. In such systems top phase has significant alcohol content and insignificant electrolyte content, bottom phase has significant electrolyte content and insignificant alcohol content.

Liquid electrolytes in batteries are typically treated as macroscopically homogeneous ionic transport media, despite having complex chemical composition and atomistic solvation structures, thus leaving a knowledge gap of microstructural characteristics. A promising electrolyte system design has recently been developed with the title of a localized high-concentration electrolyte (LHCE). These electrolytes are a summation of three components – a charge-carrying salt, a solvent that solvates the salt, and a diluent that is highly immiscible with the salt.

Flexible and scalable energy storage solutions are necessary for mitigating fluctuations of renewable energy sources. The main advantage of redox flow batteries is their ability to decouple power and energy. However, they present some limitations including poor performance, short-lifetimes, and expensive ion-selective membranes as well as high price, toxicity, and scarcity of vanadium compounds. We report a membrane-free battery that relies on the immiscibility of redox electrolytes and where vanadium is replaced by organic molecules.

Perfluorochemicals (PFCs), which are also known as fluorocarbons or perfluorocarbons, are chemical substances having a high solubility for respiratory gases.

These substances are however immiscible with blood and if introduced into the circulation in an unmodified form could cause embolic phenomena.

Abstract:

Redox flow batteries (RFB) are a critical technology for stationary grid-scale energy storage, with potential usage with intermittent power sources, such as wind and solar. RFBs are attractive for long-duration energy storage because the anolyte and catholyte are stored separately external to the electrochemical reactor, which allows the RFBs to be modular and stationary. Separating the electrolytes and the electrochemical cell decouples energy and power densities, unlike batteries that store charge in the solid-state, such as Li-ion, Pb-acid, or Ni-Cd. A standard RFB chemistry is the all-vana

Aqueous biphasic systems (ABS) formed by water, ionic liquids (ILs), and salts, in which the two phases are water rich, are emonstrated here to act as potential membrane-free batteries. This concept is feasible due to the selective enrichment of redox organic molecules in each aqueous phase of ABS, which spontaneously form two liquid-phases above given concentrations of salt and IL. Therefore, the required separation of electrolytes in the battery is not driven by an expensive membrane that hampers mass transfer, but instead, by the intrinsic immiscibility of the two liquid phases.

Abstract:

The most used electrical contact system in electronics and microelectronics is Cu/Ni(Ni-P)/Au, which offers an interesting combination of high electrical conductivity, corrosion resistance, and wear resistance. However, the top Au thin layer being porous, a galvanic coupling between NiP and Au, and then Cu and Au appears that renders the system unusable. Au being highly expensive, the development of more inexpensive and reliable plating materials such as Ag or Pd can be experimented. Ag is widely considered as an economical alternative to Au. Ag and Au top-coats are traditionally obtained from

Abstract:

Seawater is a promising electrolyte that can replace conventional distilled water-based electrolytes in that they are affordable and abundant. In the Na seawater battery, oxygen evolution reaction and oxygen reduction reaction occur in a single electrode during the charge and discharge process respectively. To obtain high energy efficiency of the Na-seawater battery, both oxygen electrocatalytic activity should be improved. In addition, the electrochemical reaction occurring in natural seawater may be hindered by chlorine ions. Side reactions such as chlorine evolution reaction or poisoning of

Abstract:

Rechargeable energy storage systems that can efficiently operate at ultra-low temperatures down to -50°C or lower are needed to support Arctic zone development and aerospace exploration. Existing batteries today such as Li-ion and Pb-acid batteries all lose functions at colder temperatures. We have discovered a battery chemistry for which the amount of energy stored actually increases as temperature decreases, and storage cost commensurately decreases. Furthermore, this novel battery is composed of low-cost, widely available materials, and has a simple design that is self-assembling. In our st

Abstract:

Abstract The temperature rise effect on the electrochemical activity of catalysts on a copper substrate in alkaline alcohol solutions has been studied. The object of research was bimetallic PdFe/Cu and NiCo/Cu catalysts obtained by galvanic deposition on a copper substrate. The studies were carried out in immiscible liquids EtOH + K2HPO4 + H2O. The upper phase in this system of liquids is aqueous solutions of ethanol (“alcohol layer”), the lower phase is aqueous solutions of dipotassium phosphate K2HPO4 (“salt layer”). It was found that elevate temperature from 20°C to 60°C improve the activit

Abstract:

Investigations of electron transfer dynamics across the solid|liquid interface defines the cornerstones of electrochemistry. In theory electrons or ions moving across any phase boundary may be controlled or monitored, as long as there is a suitable donor and acceptor pair on either side of the boundary. Of course, there have been other interfaces which have been well characterized, such as the interface between two immiscible liquids, solid/solid junctions, etc. As a general rule, gases have poor conductivity due to the absence of any mobile charge carriers. Plasmas are the exception to this r
