With the transportation sectors of industrialized countries on the rise and greenhouse gas emissions at an all-time high, many scientists and engineers are searching for the next-generation of transportation. From hybrid to electric to hydrogen, alternative energy sources for vehicles are being explored and tested throughout the scientific community. Now, many are wondering which technology will win in the race between battery- and hydrogen-powered cars.

A recent open access paper published in the Journal of The Electrochemical Society (JES) explores this topic. Authors Hubert A. Gasteiger, Jens-Peter Suchsland, and Oliver Gröger have outlined the technological barriers for next-generation vehicles in “Review—Electromobility: Batteries or Fuel Cells?” This paper comes as part of the recent JES Collection of Invited Battery Review Papers.

The majority of today’s vehicles depend on petroleum-based products in internal combustion engines to operate. The burning of these fuels results in the emission of greenhouse gasses. The majority of these transportation sector greenhouse gas emissions do not come from large modes of transportation such as aircrafts or ships—but are primarily produced by cars, trucks, and SUVs.

In the recently published review, the authors describe the possibilities of extended range electric vehicles, the challenges in hydrogen fuel cell vehicles, and the potential for new materials to be used in these applications.

Opening of the ECS Korea Section-KIST Joint Symposium on Electrochemical CO₂ Conversion in Gwangju, South Korea.

The Korea Section Symposium (Organizers: Prof. Yung-Eun Sung, Prof. Soo-Kil Kim and Dr. Byoung Koun Min) was held on April 2, 2015 at the Kimdaejung Convention Center in Gwangju, Korea.

This year, the event was held as a Joint Symposium with the Korea Institute of Science and Technology, with the title “ECS Korea Section-KIST Joint Symposium on Electrochemical CO₂ Conversion.” It was composed of seven talks on electrocatalysts and systems for electrochemical reduction of CO₂.

Flow Batteries for Grid-Scale Energy Storage
Large-scale energy storage is required to meet a multitude of current energy challenges. These challenges include modernizing the grid, incorporating intermittent renewable energy sources (so as to dispatch continuous electrical energy), improving the efficiency of electricity transmission and distribution, and providing flexibility of storage independent of geographical and geological location.

The development and commercialization of Li-ion batteries in recent decades is without doubt the most important and impressive success of modern electrochemistry.

The Journal of The Electrochemical Society (JES) is publishing focus issues related to IMLB (International Meeting on Lithium Batteries) beginning with the 2014 meeting. Important to note is that this focus issue is completely Open Access, enabling a much broader audience to read these papers than would have access with a subscription-only issue.

Go to the table of contents now!

Twenty-one papers have here been selected for this focus issue. These papers touch upon many important new aspects in the field and illustrate well the wide spectrum of topics that were discussed at the IMLB 2014 meeting.

The most important international conference event in the Li battery community is the biannual International Meeting on Lithium Batteries; a conference series founded by Bruno Scrosati which began 33 years ago. The IMLB meeting can, in fact, be seen as among the most important conferences related to power sources in general.

Materials scientists have developed a new technique that could provide a simpler and more effective way to produce electrode materials for batteries and supercapacitors, which could potentially lead to devices with improved energy and power densities.

The researchers have unlocked this new battery technology by exposing tiny bits of graphene to a process that is very similar to deep-frying.

Prior to this development, scientists had difficulty using graphene in electrodes due to the difficulty encountered when processing the material. However, the researchers out of Yonsei University have learned how to harness the material’s electrical and mechanical properties while retaining its high surface are by using an alternative technique.

The aluminum-air battery has the potential to serve as a short-term power source for electric vehicles.

A new long-life aluminum-air battery is set to resolve challenges in rechargeable energy storage technology, thanks to ECS member Ryohei Mori.

Mori’s development has yielded a new type of aluminum-air battery, which is rechargeable by refilling with either salt or fresh water.

The research is detailed in an open access article in the Journal of The Electrochemical Society, where Mori explains how he modified the structure of the previous aluminum-air battery to ensure a longer battery life.

Theoretically, metal-air technology can have very high energy densities, which makes it a promising candidate for next-generation batteries that could enable such things as long-range battery-electric vehicles.

However, the long-standing barrier of anode corrosion and byproduct accumulation have halted these batteries from achieving their full potential. Dr. Mori’s recently published paper, “Addition of Ceramic Barriers to Aluminum-Air batteries to Suppress By-product Formation on Electrodes,” details how to combat this issue.

Scientists out of the University of Waterloo are one step closer to inventing a cheaper, lighter and more powerful rechargeable battery for electric vehicles. At the heart of this discovery lies a breakthrough in lithium-sulfur batteries due to an ultra-thin nanomaterial.

This from the University of Waterloo:

Their discovery of a material that maintains a rechargeable sulfur cathode helps to overcome a primary hurdle to building a lithium-sulfur (Li-S) battery. Such a battery can theoretically power an electric car three times further than current lithium-ion batteries for the same weight – at much lower cost.

X-ray absorption spectra, interpreted using first-principles electronic structure calculations, provide insight into the solvation of the lithium ion in propylene carbonate.

The Electrochemical Society’s Stephen Harris, along with a team of researchers from  Berkeley Lab, have found a possible avenue to a better electrolyte for lithium-ion batteries.

Harris – an expert on lithium-ion batteries and chemist at Berkeley Lab’s Materials Science Division – believes that he and his team have unveiled something that could lead to applying lithium-ion batteries to large-scale energy storage.

Researchers around the world know that in order for lithium-ion batteries to store electrical energy for the gird or power electric cars, they must be improved. The team at Berkeley decided to take on this challenge and found surprising results in the first X-ray absorption spectroscopy study of a model lithium electrode, which has provided a better understanding of the liquid electrolyte.

Previous simulations have predicted a tetrahedral solvation structure for the lithium-ion electrolyte, but the new study yields different results.

A new study shows remarkable parallels between hydrogen and graphene under extreme pressures.

The study was conducted by Carnegie’s Ivan Naumov and Russell Hemley, and can be found in the December issue of Accounts of Chemical Research.

Because of hydrogen’s simplicity and abundance, it has long been used as a testing ground for theories of the chemical bond. It is necessary to understand chemical bonding in extreme environments in order to expand our knowledge of a broad range of conditions found in the universe.

It has always been difficult for researchers to observe hydrogen’s behavior under very high pressure, until recently when teams observed the element at pressures of 2-to-3.5 million times the normal atmospheric pressure.

Under this pressure, it transforms into an unexpected structure that consists of layered sheets, rather than close-packed metal – which had been the prediction of scientists many years ago.
