The Massachusetts Institute of Technology (MIT) Climate CoLab is currently running a series of contests where people all over the world can work with experts and each other to develop climate change solutions.

The waste management contest is now open. We are seeking practical proposals to reduce greenhouse gas emissions from waste and waste management that can be rapidly implemented, scaled-up and/or replicated. We especially encourage proposals that address national (e.g. Intended Nationally Determined Contributions or National Adaptation Plans) and/or sub-national strategies to address the challenges of climate change and aim to help countries, states, and communities implement those strategies.

The Judges’ and Popular Choice Winners will be invited to MIT to present their proposal, enter the Climate CoLab Winners Program and be eligible for the $10,000 Grand Prize. All award winners will receive wide recognition and visibility by the MIT Climate CoLab. See last year’s conference. Entries are due May 23, 2016. Early submissions welcome — entries can be edited until the contest deadline.

Even if you don’t have new ideas yourself, you can help improve other people’s ideas and support the ones you find most promising. Visit the CoLab to learn more.

While we may have a good understanding of battery application and potential, we still lack a great deal of knowledge about what is actually happening inside a battery cell during cycles. In an effort to build a better battery, ECS members from the U.S. Department of Energy’s Argonne National Laboratory have made a novel development to improve battery performance testing.

Future of energy

The team’s work focuses on the design and placement of the reference electrode (RE), which measure voltage of the individual electrodes making up a battery cell, to enhance the quality of information collected from lithium-ion battery cells during cycles. By improving our knowledge of what’s happening inside the battery, researchers will more easily be able to develop longer-lasting batteries.

“Such information is critical, especially when developing batteries for larger-scale applications, such as electric vehicles, that have far greater energy density and longevity requirements than typical batteries in cell phones and laptop computers,” said Daniel Abraham, ECS member and co-author of the newly published study in the Journal of The Electrochemical Society. “This kind of detailed information provides insight into a battery cell’s health; it’s the type of information that researchers need to evaluate battery materials at all stages of their development.”

Edward Goodrich Acheson (1856-1931), one of the charter members of ECS, is best known for having invented and commercialized carborundum, an artificial graphite.

Biography

Acheson was born in southwestern Pennsylvania and raised its coal fields. At the age of 16, after his father died, he left school to help support his family. Nevertheless, Acheson devoted his nights to the scientific endeavors, especially electrical experiments.

In 1880, Acheson attempted to sell a battery of his own invention to Thomas Edison, who ended up hiring him to assist with his research. He experimented with creating a conducting carbon that Edison could use in his electric light bulbs.

After working for Edison for four years, Acheson left his employ to become an independent inventor. In 1891, Acheson acquired access to an electric
generating plant and attempted to use electric heat to impregnate clay with carbon. What resulted from this experiment was his discovery of a crystalline substance that had value as an abrasive, which Acheson named “carborundum” (also known as silicon carbide).

In 1894, he established the Carborundum Company in Monongahela City, Pennsylvania, which created grinding wheels, whet stones, knife sharpeners, and powdered abrasives. Later, Acheson used his electric furnace to produce artificial graphite, which  he commercialized, discovering that various organic substances allowed colloidal suspension of particles of graphite mixed in oil or water.

Acheson received 70 patents related to abrasives, graphite products, reduction of oxides, and refractories. ECS awarded him the first Acheson Award, named in his honor, in 1931.

Research highlighting transformative scientific discoveries

ECS published its first Editors’ Choice article on Tuesday, March 22, 2016 in the Journal of The Electrochemical Society. The article, entitled “Communication—Comparison of Nanoscale Focused Ion Beam and Electrochemical Lithiation in β-Sn Microspheres,” details transformative findings in the dosage and spatial distribution of lithiation.

Editors’ Choice articles are a special designation of ECS’s newly established Communication articles, which are designed to highlight breakthrough preliminary research and bolster the scientific discovery process. ECS journal editors designate exemplary Communication articles as Editors’ Choice when the research presented is transformative, detailing either novel advancements in a field or completely new discoveries.

“This paper introduces the use of a focused Li-ion beam (Li-FIB) as a new tool that is designed to probe lithiation mechanism at the nanoscale,” says Nick Wu, Associate Editor of the Journal of The Electrochemical Society. “This technique, which employs a focused Li-ion beam with spot size of a few tens of nanometers and kinetic energy of a few keV, enables precise dosage and spatial distribution of lithiation.”

Papers chosen as Editors’ Choice are regarded as having the highest quality, impact, significance, and scientific or technological interest to electrochemical and solid state science and technology. In order to disseminate these findings to the scientific community at large and open the door to faster developments of practical applications, all Editors’ Choice articles are published Open Access.

“Furthermore,” Wu says, “lithiation in this technique is carried out in the absence of electrolytes so that it allows the study of lithiation dynamics solely in the bulk or surface layers (coatings) of the electrode material without the confounding influences from the electrolyte interactions.”

Each paper undergoes the same rigorous peer-review process associated with ECS journals, with Editors’ Choice articles showing extraordinary direction, concept, interpretation, field, or way of doing something.

Rooftops can provide more than shelter from the elements; they may also provide a goldmine of untapped energy production.

The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) recently issued a report stating that rooftop solar panels have the potential to power nearly 40 percent of the U.S.

“It is important to note that this report only estimates the potential from existing, suitable rooftops, and does not consider the immense potential of ground-mounted PV,” co-author of the report Robert Margolis said. “Actual generation from PV in urban areas could exceed these estimates by installing systems on less suitable roof space, by mounting PV on canopies over open spaces such as parking lots, or by integrating PV into building facades. Further, the results are sensitive to assumptions about module performance, which are expected to continue to improve over time.”

Essentially, solar panels could have limitless possibles. However, land is a precious commodity. Roofs, however, provide a space that typically goes unused to generate a huge amount of power for the U.S.

A research team aims to make a battery and solar cell hybrid out of two single systems.

People across the globe are looking toward renewable solutions to change the landscape of energy. But what happens when the sun goes down and the wind stops blowing? In order to guarantee green energy that is consistent, reliable energy storage systems are critical.

“Currently, single systems of photovoltaic cells which are connected together — mostly lead-based batteries and vast amounts of cable — are in use,” said Ilie Hanzu, TU Graz professor and past member of ECS. “We want to make a battery and solar cell hybrid out of two single systems which is not only able to convert electrical energy, but also store it.”

The idea of a battery and solar cell hybrid is completely novel scientific territory. With this project, entitled SolaBat, the team hopes to develop a product that has commercial applications. For this, the scientists will have to develop the perfect combination of functional materials.

“In the hybrid system, high-performance materials share their tasks in the solar cell and in the battery,” Hanzu said. “We need materials that reliably fulfill their respective tasks and that are also electrochemically compatible with other materials so that they work together in one device.”
