ECS student member Fudong Han and former member Chunsheng Wang have developed a novel solid state battery comprised of just one material that can both move and store electricity.

This new battery could prove to be revolutionary in the area of solid state batteries due to its incorporation of electrodes and electrolytes into a single material.

“Our battery is 600 microns thick, about the size of a dime, whereas conventional solid state batteries are thin films — forty times thinner. This means that more energy can be stored in our battery,” said Han, the first author of the paper and a graduate student in Wang’s group.

This from the University of Maryland:

The new material consists of a mix of sulfur, germanium, phosphorus and lithium. This compound is used as the ion-moving electrolyte. At each end, the scientists added carbon to this electrolyte to form electrodes that push the ions back and forth through the electrolyte as the battery charges and discharges. Like a little bit more sugar added at each end of a cookie-cream mixture, the carbon merely helps draw the electricity from side to side through the material.

A new study by two ECS published authors, David Muller and Jiwoong Park, has led to an electronic piece that is just three atoms thick.

The researchers have unveiled a process to develop ultra-thin transistors made from TMD, otherwise known as transition metal dichalcogenide. This material is novel in the fact that it possesses properties that make it a perfect fit for solar cells, light detectors, or semiconductors.

Researchers have been examining TMDs for some time now, but have been finding it difficult to get them to work consistently. This new study has discovered the best process yet to manufacture the materials, which could lead to a breakthrough in the future of electronics and possibly bring about an end to Moore’s law.

Elon Musk has just announced the new Tesla Energy division, which aims to move the energy grid away from dependency on fossil fuels and toward renewables.

The new line features a suite of rechargeable lithium-ion batteries—similar to the batteries used in the Tesla vehicles—for homes, businesses, and utilities. The company states that the battery can store renewable energy at a residential level for load shifting, backup power, and self-consumption of solar power generation.

During his announcement, Musk stated that this move could help change the “entire energy infrastructure of the world.”

The batteries have the ability to charge during non-peak energy usage hours and provide the home with energy during peak usage hours. The batteries are available at 10kWh or 7kWh, with a selling price of $3,500 and $3,000 respectively.

To put this into perspective, an energy comparison firm estimates that 1kWh can produce enough power for a full washing machine cycle.

Tesla hopes that this new line of batteries gets us closer to zero emission power generation and fosters a clean energy ecosystem.

Registration for the ECS Conference on Electrochemical Energy Conversion & Storage with SOFC-XIV, convening in Glasgow, July 26-31, 2015, is now open. The plenary session will feature Nigel Brandon, Director of the Sustainable Gas Institute at Imperial College London.

Prof. Nigel Brandon OBE FREng is also Director of the UK Hydrogen and Fuel Cells Hub, and Co-Director of the UK Energy Storage Hub. He held research positions with BP and Rolls-Royce before joining Imperial College as a Senior Lecturer in electrochemical engineering in 1998.

In 2000 he was a founder of the fuel cell company Ceres Power, acting as CEO to 2003, CTO to 2006 and Chief Scientist to 2009. He was appointed to the Shell Chair in Sustainable Development in Energy in 2005 and the BG Chair in Sustainable Gas in 2014.

He was the UK focal point with China in energy and climate change from 2007 to 2011, and Senior Research Fellow in Energy to the UK Research Councils from 2005 to 2014.

“You’re not going to solve the energy problem by separating paper and plastic. We need to transition out of our dependency on fossil fuels and into renewables. As a society, it is really up to us to change.”

ECS Fellow Héctor D. Abruña recently spoke on the importance of developing better batteries to change the energy landscape at a Charter Day Weekend lecture at Cornell University.

The energy infrastructure as it exists today cannot maintain in its current form in the years to come. The United Nations expects the world’s population to reach 9.6 billion by 2050. Compare this to the current 7.2 billion population and the current issues with the energy infrastructure and the need for change becomes quite apparent.

Fortunately, Abruña and scientists like him are working to move us toward a more energy efficient and sustainable future through developments in fuel cells and batteries, which will power energy efficient and environmentally safe cars, as well as reshape the energy infrastructure itself.

“If we have any hope of solving the energy problems, we need better energy conversion and storage,” said Abruña.

Former ECS member Teri Odom has assisted in the development of the first ever liquid nanoscale laser. This development could lead to some very practical applications, as well as guiding researchers one step closer to developing a “lab on a chip” for medical diagnostics.

The laser is relatively simple to create, cheap to produce, and has the ability to operate at room temperature. Because the device works in real time, users can quickly and simply produce different colors.

This from Science World Report:

The laser’s cavity itself is made up of an array of reflective gold nanoparticles where the light is concentrated around each nanoparticle and then amplified. In contrast to conventional laser cavities, no mirrors are required for the light to bounce back and forth. As the laser color is tuned the nanoparticle cavity stays fixed and does not change.

Registration for the ECS Conference on Electrochemical Energy Conversion & Storage with SOFC-XIV is now open. The conference is set to take place this July in Scotland, a fitting venue when looking at the country’s goal of utilizing 100 percent renewable energy by 2020.

In 2012, Scotland pulled 40 percent of its power from renewable resources—a 24 percent increase over 2010.

Scotland is expected to hit the hallway point on the path of obtaining 100 percent renewable this year, making it the perfect platform for some of the top researchers globally in fuel cells and batteries.

After a several year hiatus, the Chicago Section began the revitalization process in April 2015. Leading the effort in reengaging section members and activity are Alan Zdunek and Jordi Cabana from the University of Illinois at Chicago (UIC) and Eungje Lee and Arturo Gutierrez from Argonne National Laboratory (ANL). They will serve as the interim executive board for the coming year.

A kick-off meeting/social reception is planned during the ECS 227th Meeting in Chicago, IL on Monday, May 25th from 6:00 p.m. to 7:00 p.m., immediately following The ECS Lecture at the plenary. The reception will be jointly hosted by the Chicago Section, the Joint Center for Energy Storage Research (JCESR) and the Center for Electrochemical Energy Science (CEES) and the Chemical Sciences and Engineering Division at Argonne National Laboratory.

All ECS members are invited to participate in the event to learn more about future Chicago Section events and the program highlights from JCESR and CEES.
