Our world has no shortage of problems to solve. We now stand at a critical juncture for global action to address our most pressing challenges; from the COVID pandemic to climate change and so much more.
IBM has long recognized the urgency to find more sustainable solutions to tackle these problems (The Urgency of Science). For the first time in history we have the right tools at our disposable to do so. AI (artificial intelligence)—combined with advanced computing and access to enormous volumes of data via a secure and open hybrid cloud—can significantly accelerate the process of scientific discovery and the creation of more sustainable materials for use across a broad range of industries, including energy and batteries.
In its first Science for Solving Society’s Problems Challenge, ECS partnered with the Bill & Melinda Gates Foundation to leverage the brainpower of electrochemists and solid state scientists, working to find innovative research solutions to some of the world’s most pressing issues in water and sanitation. A total of seven projects were selected, resulting in a grand total of $360,000 in funding.
The researchers behind one of those projects recently published an open access paper in the Journal of The Electrochemical Society discussing their results in pursuing a single-use, biodegradable and sustainable battery that minimizes waste. The paper, “Evaluation of Redox Chemistries for Single-Use Biodegradable Capillary Flow Batteries,” was published August 18 and authored by Omar Ibrahim, Perla Alday, Neus Sabaté, Juan Pablo Esquivel (pictured with prototype at right), and Erik Kjeang.
ECS’s Electrochemical Energy Summit brings together policymakers and researchers from around the globe to discuss the ways in which science impacts the planet’s key sustainability issues. During the 232nd ECS Meeting, taking place October 1-6 in National Harbor, MD.
The 7th International ECS Electrochemical Energy Summit: Human Sustainability – Energy, Water, Food, and Health, is set to include three distinct symposia: Energy-Water Nexus; The Brain and Electrochemistry; and Sensors for Food Safety, Quality, and Security.
The deadline for abstract submission for the 232nd ECS Meeting is April 7. Submit today!
The Energy-Water Nexus symposium, organized by ECS fellow Eric Wachsman, will focus on the connection between energy and water and emerging technologies that could improve access to clean, safe, and affordable resources across the globe. In addition to technical sessions ranging from membranes for water purification to fuel cells, the symposium will feature talks from members of federal agencies, such as the U.S. Department of Energy and the U.S. Department of Interior, to discuss funding opportunities.
ECS, in partnership with the Toyota Research Institute of North America (TRINA), a division of Toyota Motor Engineering & Manufacturing North America, Inc. (TEMA), is requesting proposals from young professors and scholars pursuing innovative electrochemical research in green energy technology.
Global development of industry and technology in the 20th century, increased production of vehicles and the growing population have resulted in massive consumption of fossil fuels. Today, the automotive industry faces three challenges regarding environmental and energy issues: (1) finding a viable alternative energy source as a replacement for oil, (2) reducing CO2 emissions and (3) preventing air pollution. Although the demand for oil alternatives—such as natural gas, electricity and hydrogen—may grow, each alternative energy source has its disadvantages. Currently, oil remains the main source of automotive fuel; however, further research and development of alternative energies may bring change.
The purpose of the ECS Toyota Young Investigator Fellowship is to encourage young professors and scholars to pursue research in green energy technology that may promote the development of next-generation vehicles capable of utilizing alternative fuels. Electrochemical research has already informed the development and improvement of innovative batteries, electrocatalysts, photovoltaics and fuel cells.
Through this fellowship, ECS and TRINA hope to see more innovative and unconventional technologies borne from electrochemical research.
The fellowship will be awarded to a minimum of one candidate annually. Winners will receive a restricted grant of no less than $50,000 to conduct the research outlined in their proposal within one year. Winners will also receive a one-year complimentary ECS membership as well as the opportunity to present and/or publish their research with ECS.
Researchers from the University of Connecticut are pushing toward a hydrogen economy with the development of a new catalyst for cheaper, light-weight hydrogen fuel cells.
The catalyst — made of graphene nanotubes infused with sulfur — could potentially work to make hydrogen capture more commercially viable.
This development comes during a time where many people are looking to hydrogen in the search for a new, sustainable energy source. While hydrogen may be abundant, it often requires a costly and energy-consuming process to produce. However, if scientists could find an affordable and efficient way to capture hydrogen, it may begin to shift society away from the fossil fuel-driven economy toward a hydrogen economy.
The material developed by the University of Connecticut professors currently shows results that are competitive with some of the top materials traditionally used in these processes, but at a fraction of the cost.
The secret lies in the non-metal catalyst that has many of the same electrochemical properties as rare earth materials.
When the loaves in your breadbox begin to develop a moldy exterior caused by fungi, they tend to find a new home at the bottom of a trash can. However, researchers have recently developed some pretty interesting results that suggest bread mold could be the key to producing more sustainable electrochemical materials for use in rechargeable batteries.
For the first time, researchers were able to show that the fungus Neurospora crassa (better known as the enemy to bread) can transform manganese into mineral composites with promising electrochemical properties.

“We have made electrochemically active materials using a fungal manganese biomineralization process,” says Geoffrey Gadd of the University of Dundee in Scotland. “The electrochemical properties of the carbonized fungal biomass-mineral composite were tested in a supercapacitor and a lithium-ion battery, and it [the composite] was found to have excellent electrochemical properties. This system therefore suggests a novel biotechnological method for the preparation of sustainable electrochemical materials.”
This from University of Dundee:
In the new study, Gadd and his colleagues incubated N. crassa in media amended with urea and manganese chloride (MnCl2) and watched what happened. The researchers found that the long branching fungal filaments (or hyphae) became biomineralized and/or enveloped by minerals in various formations. After heat treatment, they were left with a mixture of carbonized biomass and manganese oxides. Further study of those structures show that they have ideal electrochemical properties for use in supercapacitors or lithium-ion batteries.
The manganese oxides in the lithium-ion batteries are showing an excellent cycling stability and more than 90 percent capacity after 200 cycles.
A research team from the University of Texas at Arlington comprised of both present and past ECS members has developed a new energy cell for large-scale solar energy storage even when it’s dark.
Solar energy systems that are currently in the market and limited in efficiency levels on cloudy days, and are typically unable to convert energy when the sun goes down.
The team, including ECS student member Chiajen Hsu and two former ECS members, has developed an all-vanadium photoelectrochemical flow cell that allows for energy storage during the night.
“This research has a chance to rewrite how we store and use solar power,” said Fuqiang Liu, past member of ECS and assistant professor in the Materials Science and Engineering Department who led the research team. “As renewable energy becomes more prevalent, the ability to store solar energy and use it as a renewable alternative provides a sustainable solution to the problem of energy shortage. It also can effectively harness the inexhaustible energy from the sun.”
“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.
