Looking back and forward to the 240th ECS Meeting

On June 14, 78 graduate and undergraduate students from around the world received notification that their posters had been chosen for exhibition at the Z01 General Student Poster Session at the 240th ECS Meeting in Orlando, FL, from October 10-14, 2021. The poster session is a forum for students to present research results to ECS meeting attendees including the most active researchers in electrochemistry and solid state science and technology. Students choose to be part of the competition for cash awards recognizing the best poster presentations.

Byron Gates and Jeff Warren lecture on July 23, 2021

The ECS British Columbia Student Chapter invites students, post-docs, professors, and anyone interested in electrochemistry, materials, or renewable energy, to our 10th Annual Young Electrochemists Symposium. This milestone meeting is online via Zoom due to the unprecedented nature of COVID-19. Hopefully, this is the last online meeting before we gather in person again. 

We hope to see you soon at our symposium,

ECS British Columbia Student Chapter

ECS Corrosion Division Rusty Award for Mid-Career Excellence

Nominations are now being accepted for the new ECS Corrosion Division Rusty Award for Mid-Career Excellence. The award was established recently by the ECS Honors and Awards Program and Corrosion Division to recognize a mid-career scientist or engineer’s achievements and contributions to the field of corrosion science and technology.

Award

A framed certificate; US $1,000 prize; and complimentary meeting registration are awarded to the recipient. The award is bestowed at the fall ECS biannual meeting; the recipient is expected to lecture on their research at a designated ECS Corrosion Division symposium during that meeting. Up to US $1,000 may be available to assist with travel expenses to facilitate attendance at the meeting. (more…)

During battery (dis)charging, lithium (de)intercalation in electrodes is usually spatially non-uniform across multiple length scales. Such a phenomenon is a major impediment to battery performance and life as it causes energy under-utilization and induces over-(dis)charging, etc. While reaction heterogeneity is often attributed to mass transport limitation, this talk highlights the important roles of thermodynamic factors including elastic energy and phase transformations, the understanding of which is important for the development of mitigation strategies. Through combined modeling and characterization, how stress could destabilize the lithium (de)lithiation front in single crystalline and polycrystalline intercalation compounds is elucidated. Also, a fundamental driving force for dendrite growth on the lithium metal anode during electrodeposition is provided. Stress relief thus offers a promising approach to improving reaction uniformity at the particle level. At the cell level, the reaction distribution that within the porous electrode is strongly influenced by how the electrode’s equilibrium potential varies with the state of charge, is discovered. Two types of prototypical reaction behavior emerge from common electrode materials with significant impact on the thick electrode performance. This finding leads to an efficient analytical model for optimizing battery configurations in place of common battery cell simulations. (more…)
