Sentences with phrase «aqueous electrolyte»

The phrase "aqueous electrolyte" refers to a liquid containing dissolved salts or ions that can conduct electricity. It means a watery solution where these dissolved substances can help in the flow of electric current. Full definition
These methods fail, however, for metals where the diffusion of hydrogen is relatively slow, and also in cases where metals strongly react with aqueous electrolyte solutions.
«Zinc - air batteries are attractive because of the abundance and low cost of zinc metal, as well as the non-flammable nature of aqueous electrolytes, which make the batteries inherently safe to operate,» Dai said.
Besides energy density, a major reason for the diminishing role of zinc batteries is the poor reversibility of the zinc chemistry in aqueous electrolytes.
Second, the solubility of cadmium in basic aqueous electrolyte solutions is sufficiently low that the cadmium does not tend to dissolve in the electrolyte and migrate to the positive electrode or elsewhere within the battery.
The researchers discovered that this saline solution displays an electrochemical stability of up to 2.6 volts — i.e. nearly twice as much as other aqueous electrolytes.
Unlike other electrochromic substances, however, researchers have struggled to comprehend how coloration occurs in NiO in the presence of common aqueous electrolytes.
The external tanks in PNNL's new battery hold aqueous electrolytes, watery solutions with dissolved chemicals that store energy.
Pham, along with LLNL researcher Eric Schwegler, Robert Seidel and Steven Bradforth from the University of Southern California, and Marco Govoni and Giulia Galli from the Argonne National Laboratory and the University of Chicago, have presented an experimentally validated simulation strategy for computing the electronic properties of aqueous electrolytes.
The next step is to understand how long these intense fields last in aqueous electrolytes, determine what types of molecular configurations are needed to create these long - lasting fields, and quantify the distribution of energy gaps between the various excited electronic states.
Many of us are familiar with electrolytic splitting of water from their school days: if you hold two electrodes into an aqueous electrolyte and apply a sufficient voltage, gas bubbles of hydrogen and oxygen are formed.
Flow batteries are centred around two aqueous electrolytes, which are held in separate tanks when the battery is idle.
In their experiment, they found that as they flushed their aqueous electrolyte with air, and alternately with CO2, between their porous electrodes, a supply of electricity began to build up.
The research follows a 2015 study in Science that produced a similar 3.0 volt battery with an aqueous electrolyte but was stymied from achieving higher voltages by the so - called «cathodic challenge,» in which one end of the battery, made from either graphite or lithium metal, is degraded by the aqueous electrolyte.
The review details capture and transport of light in the semiconductor, electrocatalysis, ion transport in the membrane and aqueous electrolytes, transport of product gas, and describesmulticomponent interactions between these physicochemical phenomena.
