Winter 2017 InterfaceBy: Johna Leddy, ECS President

“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.

InterfaceThe 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.

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.

Winter 2017 InterfaceThe 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 LiNi0.5Mn1.5O4 cathode and a Li4Ti5O12 anode.

InterfaceAs 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.

Performance of Three-Dimensional LiMn2O4/Carbon Composite Cathodes Prepared Via Sol-Gel Impregnation

With the ever advancing improvements in electronics and display technologies, it is crucial that Li-ion batteries are able to rise to the challenge of powering next generation consumer electronics. Consequently, the development of electrode materials for Li-ion batteries that are capable of delivering high capacities with stable capacity retention is of the utmost importance. Researchers from the University of Bremen have investigated the fabrication of 3D composite cathodes consisting of LiMn2O4 particles deposited directly onto an electrically conductive matrix of carbon fibres via sol-gel impregnation. The electrochemical performance of the composite cathodes was evaluated as a function of the number of sol impregnation steps. Through systematic galvanostatic cycling, the researchers determined that high capacity cathodes could be obtained from increased filling of the carbon matrix with the LMO sol. A cathode sample after four filling cycles demonstrated a discharge capacity of 132mAh g-1 after 50 cycles, corresponding to ~89% of the theoretical capacity of LiMn2O4.

Additionally, as a proof-of-concept, LMO cathodes were cycled against Lithium Titanate (LTO) anodes in a solid state battery (SSB) setup. The evaluation of these cells offers valuable insight for future SSB applications.
