“It is all about power. If you have power, you have water. If you have water, you have food. If you have food, you can go to school. If you go to school, you have tools to think. If you have access and tools to think, you can learn those next door are not so different. You can work together to mitigate energy disparates and so reduce conflict. It is all about power.”

-ECS satellite OpenCon, October 2017

ECS looks to its future as a forum for research and a conduit for access and communication. Tenets of the scientific method are invariant, but practice of communication and access change. Change is driven by gradients. Without gradients, energy is minimized and the system dies, but if gradients are too steep, the system becomes unstable. History maps conflicts over energy and power. Early wars were over land for food energy. Distribution of natural resources and oil sustain conflicts for thermal energy. Gradients in energy distribution drive change and conflict. Going forward, access to critical materials and information, coupled with the skills and imagination to develop advanced technologies, will mitigate steep gradients in energy distribution.

The following are the updated guidelines for submitting student chapter updates for publication in Interface.

ECS encourages submissions of news from student chapters. Therefore, we try to keep the rules to a minimum. However, some guidance will help in preparing the material.

Point of View: Compose your submission in third person.

Timeliness: Interface is published every three months – spring, summer, fall, and winter. It is best that your chapter update includes information about events, initiatives, accomplishments, etc., from within the last three to six months.

Each year ECS gives up to five Summer Fellowships to assist students in continuing their graduate work during the summer months in a field of interest to the Society.

Congratulations to the four Summer Fellowship recipients for 2017. The Society thanks the Summer Fellowship Committee for their work in reviewing the applications and selecting four excellent recipients.

Mapping Nanoscale Ion Transport
Lushan Zhou

Transport of ions at small length scales plays critical roles in almost all physical and biophysical processes. Investigation of local ion transport properties requires tools for direct visualization of spatially distributed ions at interfaces. Scanning ion conductance microscopy (SICM), a scanned nanoscale pipette, allows high resolution non-contact topography
imaging of samples bathed in electrolyte and therefore is well-suited for nanoscale ion transport studies. Read more.

Below is an excerpt from an article published in the winter 2017 edition of Interface.

By: Durga Misra, New Jersey Institute of Technology

The explosive progress of information technology and 5th generation communication technology enables the introduction of the Internet of Things, where the network of physical objects—devices, vehicles, and buildings embedded with sensors, electronics, software, and network connectivity—permits these physical objects to collect and exchange data. The use of dielectric materials in sensors for a multitude of applications such as self-driving cars has made the dielectric science and technology research even more significant than before.

More than seventy years ago, in 1945, it all started with establishing the Electric Insulation Division in ECS to offer an interdisciplinary forum to discuss the science of the materials used for electrical insulation in power transmission. With the advancement of technology, when integrated circuits became popular, the division became the Dielectrics and Insulation Division in 1965. In 1990, it became the Dielectric Science and Technology Division due to extensive growth in electronic manufacturing technology. Today, the division still provides a strong interdisciplinary research environment.

In this issue of Interface we have focused on some of the current topics that are an integral part of current and future technologies.

The Effect of the Fluoroethylene Carbonate Additive in Full Lithium-Ion Cells

In recent years, high voltage cathode materials have attracted a great deal of attention due to the high energy densities that they offer. However, side reactions with conventional electrolytes resulting in electrolyte decomposition need to be overcome to make the use of these materials viable for commercial cells. Consequently, various electrolyte additives have been the subject of much research. A team led by researchers from Uppsala University has investigated the effect of fluoroethylene carbonate (FEC) as an electrolyte additive in full Li-ion cells consisting of a LiNi_0.5Mn_1.5O₄ cathode and a Li₄Ti₅O₁₂ anode.

As vice chair of the Industrial Electrochemistry and Electrochemical Engineering Division, it is with great pleasure that I introduce the summer 2017 edition of Interface.

The authors of the articles you are about to read all worked tirelessly, and we owe them acknowledgement and significant gratitude for putting this issue together. Without their contributions, we would not be able to deliver the consistent quality of content that you expect in Interface.

We as a division hope to highlight the diverse activities of our members.

In the following pages you will find articles authored by industrial and academic members, with foci ranging from environmental applications to mathematical modeling to large-scale industrial production of metals. Such breadth is evidence that our division’s activities, as has been the case in the past, are ever evolving.

Spray Drying-Assisted Synthesis of Li₃VO₄/C/CNTs Composites for High-Performance Lithium Ion Battery Anodes

Published in the “Focus Issue of Selected Papers from IMLB 2016 with Invited Papers Celebrating 25 Years of Lithium Ion Batteries.” Graphite-based materials continue to be the most commonly used anode materials in commercial Li-ion batteries (LIBs). However, the practical application of graphite anodes in largescale LIBs may be hindered by safety issues arising from Li dendrite formation on the surface of the anode when cycling at fast rates.

The discovery of an electric arc can be tied to the use of an electrochemical energy source. Sir Humphry Davy described in 1800 an electric discharge using electrochemical cells¹ that produced what we would call a spark, rather than an arc. However, in 1808, using an electrochemical battery containing 2000 plates of copper and zinc, he demonstrated an electric arc 8cm long. Davy is also credited with naming the phenomenon an arc (Fig. 1). An electric arc was also discovered independently in 1802 by Russian physicist Vasily Petrov, who also proposed various possible applications including arc welding. There was a long gap between the discovery of the electric arc and putting it to use.

Electrochemical cells were not a practical source to supply a sustained high current for an electric arc. A useful application of this low voltage and high current arc discharge became possible only once mechanical generators were constructed. Charles Francis Brush developed a dynamo, an electric generator, in 1878, that was able to supply electricity for his design of arc lights. Those were deployed first in Philadelphia and by 1881 a number of cities had electric arc public lights. Once that happened, the application and new discoveries for the use of the electric arc followed. Electric arc for illumination was certainly in the forefront. First, electric light extended greatly the human activities into the night and second, public street electric lights, attracting masses of spectators, were the source of admiration, inspiration, and no doubt, more invention.
