Experiments and Modeling Reveals Charging Mechanism of Promising Na-Ion Battery Material

A paper by Prof. Smith and his PhD student Aniruddh Shrivastava was recently published that explores the microscopic transport processes that influence the rate at which Prussian Blue analogues (a promising material for water-based sodium-ion batteries and desalination) charge and discharge.  Interestingly, slow electron transport is responsible for the apparent transport of sodium ions.  Download the Journal of the Electrochemical Society open-access article here for free.


UIUC Press Release: Smith makes headway in desalination technology

Professor Smith’s group, together with researchers at the european centre of excellence for sustainable water technology (Wetsus), have taken a step forward in developing a saltwater desalination process that borrows from battery technology. In their study, the researchers are focusing on new materials that could make desalination of brackish waters economically desirable and energy efficient.  You can read the full press release here and the corresponding article here.


Porous Electrodes Session @ InterPore 2017, Rotterdam

During the InterPore 2017 meeting, a mini-symposium is planned, entitled “Porous Electrodes for Desalination and Environmental Applications,” focusing on all kinds of electrochemical processes within porous electrodes (including, capacitive and faradaic) with applications related to water desalination, water treatment, environmental separations, and energy storage. For a detailed scope of the mini-symposium, see [link]. Abstract submission has opened and will close on November 14, 2016! [link]


Examples include pollutant removal, desalination of brackish and seawater using capacitive deionization (CDI), and energy storage with aqueous and non-aqueous batteries. Particular emphasis is on the mathematical modeling of transport processes within porous electrodes at multiple length scales (including macro, pore, and nano scales), the fundamental physics and thermodynamics of electrosorption in capacitive micropores and in intercalation host compounds, and surface transport processes. Convection, diffusion, and dispersion processes within porous electrodes and their impact on functional performance are of particular interest, in addition to consideration of porous (carbon) membranes that can be charged capacitively.


For any questions, do not hesitate to contact any of the mini-symposium organizers. We look forward to seeing you in Rotterdam in 2017!

Smith group desalination paper among top 10 most-read

Professor Kyle Smith and graduate student Rylan Dmello’s paper titled, “Na-Ion Desalination (NID) Enabled by Na-Blocking Membranes and Symmetric Na-Intercalation: Porous-Electrode Modeling,” published in January by the Journal of the Electrochemical Society has been one of the top 10 most-read articles for five months—and as of July, occupied the number two spot on the list. The journal’s “most read” rankings are based on full-text and pdf views.  Read more here

Battery technology could charge up water desalination

The technology that charges batteries for electronic devices could provide fresh water from salty seas, says a new study by University of Illinois engineers. Electricity running through a salt water-filled battery draws the salt ions out of the water.  Illinois mechanical science and engineering professor Kyle Smith and graduate student Rylan Dmello published their work in the Journal of the Electrochemical Society.  Read more here.
