More efficient, longer-lasting batteries are needed to ensure the future of the electric vehicle market. Thanks to Jeff R. Dahn and his Dalhousie University research team, a “million-mile battery” may soon be a reality. Dahn is Tesla’s battery research partner. In “A Wide Range of Testing Results on an Excellent Lithium-Ion Cell Chemistry to be used as Benchmarks for New Battery Technologies,” Dahn describes a new Li-ion battery cell with a single crystal NMC cathode and an advanced electrolyte. The new battery should power an electric vehicle for one million miles and last at least 20 years in grid energy storage—making Tesla’s electric-powered semi-autonomous driving cars and trucks viable.
The Electrochemical Society meetings’ plenary sessions provide unparalleled opportunities for participants. Christopher J. Jannuzzi, ECS Executive Director and CEO, described these benefits in his introduction to the 235th ECS Meeting. The plenary session brings everyone together. Colleagues create long-lasting collaborative efforts. Participants enrich and energize their professional lives. New friends are made and old friends revisited. Leading authorities showcase important innovations in the electrochemical and solid state sciences which can impact attendees’ research.
Last spring, at the 235th ECS Meeting’s plenary session, Héctor Abruña and David Lockwood received Society Awards. They spoke on new research in energy conversion and storage, and silicon-based photonic integrated circuits. (more…)
ECS’s Detroit Section is proud to present guest speaker Naoki Ota at its September section meeting. He will speak on:
“Lithium-Ion Batteries: Semi-Solid Electrode Technology—Next Generation Product / Manufacturing Platform for Lithium Ion”
The Electrochemical Society values professional and volunteer achievement in the multi-disciplinary sciences. The ECS awards reflect the professional recognition of peers. At meeting plenary sessions, participants from every symposia come together to recognize award winners—some of the greatest minds in the field—and learn about their latest research.
ECS Fellow David J. Lockwood received the Gordon E. Moore Award for Outstanding Achievement in Solid State Science and Technology at the plenary session of the 235th ECS Meeting. This award recognizes outstanding contributions to the fundamental understanding and technological applications of solid state materials, phenomena, and processes. Lockwood is a physicist and researcher emeritus at the National Research Council of Canada. His research centers on the optical properties of low-dimensional materials and focuses on Group IV and III-V semiconductor nanostructures. Lockwood presented “Silicon-Based Photonic Integrated Circuits: The Quest for Compatible Light Sources” at the 235th ECS Meeting Plenary Session. (more…)
The Electrochemical Society presents prestigious awards at its meetings that recognize outstanding scientific achievement and acknowledge exceptional service to the Society. These sessions are a great opportunity to meet peers and learn more about the leading lights of electrochemistry, as well as early-career scientists and doctoral, post-doctoral, and graduate students—the future of our field.
Among the major society awards presented at the 235th ECS Meeting, Héctor D. Abruña received the Allen J. Bard Award in Electrochemical Science. Abruña is recognized internationally as a leader in electrochemistry and analytical chemistry. Attendees gained insights into his important research and future directions—and so can you by viewing his award address, “Energy Conversion and Storage: Novel Materials and Operando Methods.” (more…)
Energy storage is crucial for the successful transition to renewable energy. Yet lithium-ion batteries have major limitations. Demand for lithium has increased exponentially, but production has not kept pace. Extracting lithium by brine mining is a long, costly, energy-intensive, and dangerous process with significant environmental impact. Access is difficult as most lithium mines are in South America.
Researchers at the Indian Institute of Technology (IIT) Madras developed a rechargeable iron ion battery to replace lithium. It uses mild steel as the anode and can store a high amount of energy. The iron battery withstood 150 cycles of charging and discharging under controlled conditions. After 50 cycles, the battery had 54 percent capacity retention. (more…)
