How do I use this calendar?

You can click on an event to display further information about it.

The toolbar above the calendar has buttons to view different events. Use the left and right arrow icons to view events in the past and future. The button inbetween returns you to today's view. The button to the right of this shows a mini-calendar to let you quickly jump to any date.

The dropdown box on the right allows you to see a different view of the calendar, such as an agenda or a termly view.

If this calendar has tags, you can use the labelled checkboxes at the top of the page to select just the tags you wish to view, and then click "Show selected". The calendar will be redisplayed with just the events related to these tags, making it easier to find what you're looking for.

Impact Session 2: Outreach and Engagement
IDL Auditorium

Join us for the second in our series of joint impact events between the School of Engineering and WMG. This seminar will explore outreach and engagement bringing together speakers from across the university who together will share their experiences, insights, and guidance. There will also be a chance to consider opportunities for taking part, for example in British Science Week in March, and in student work placements as part of the widening participation agenda.

This seminar will take place on Wednesday 01 February 2023. The session will help academics gain familiarity around outreach and engagement. This seminar is aimed at researchers at all career stages. We hope to see you there.

How Goodenough is the Ionic approximation of redox in layered oxide Li-ion battery cathodes
L3, Science Concourse

Join Prof Louis Piper (WMG) as he delivers an invited seminar titled “How Goodenough is the Ionic approximation of redox in layered oxide Li-ion battery cathodes”.

Everyone is welcome to attend, so please find his abstract and bio below.

Abstract: The 3d transition metal layered oxides derived from LiCoO2 are critical components of our lithium-ion battery technology. Simply put, the Co and Ni ions are expected to oxidize to formal 4+ configurations when all the lithium is extracted upon charging. This is based on simple electron counting within crystal field if the oxygen ions remain formally O2-. In real Li-ion batteries, the layered oxides are never fully delithiated during cycling because of degradation (oxygen loss) issues at high states of charge i.e. above 50% of lithium extraction. As a result, the ionic approximation has proven Goodenough (pun intended) to date. However, the push to increase energy densities by suppressing degradation has led to more attention on the redox mechanisms at high states of charge. In addition, lithium excess compounds have demonstrated capacities that cannot be accounted from by formal metal oxidation and indicate oxygen can participate in the charge compensation.

At WMG, we have led the integration of state-of-the-art Ni-rich Li-ion battery manufacturing of industry-relevant formats with advanced x-ray characterization. Here, I will summarize our work connecting a suite of x-ray characterization (including in-house operando EXAFS) revealing how the oxygen ions facilitate the charge compensation even in conventional layered oxides. These studies are supported by beyond density functional theory (DMFT) methods for spectroscopic simulations that reproduce our spectral observations. These findings revise the description of oxygen redox and explain why these systems suffer from accelerated oxygen loss at high states of charge.

Bio: Louis Piper is Professor of Battery Innovation and heads the Electrochemical Materials group in the Energy Directorate at WMG. He co-leads the renewed Faraday Degradation project with Prof. Clare Gray, along with leading the Faraday cell builds project upscaling new cathode materials from FutureCat consortium into real formats to improve perfomance within the Degradation Project. He has published over 175 papers (h index = 56) and was recently interviewed on BBC 2 “Secret Genius of Modern Life”. Louis did his PhD in surface Physics at Warwick University (2006) before moving stateside. First as beamline contact scientist for Boston University at NSLS, BNL (2006-2010) and then as faculty at State University of New York, Binghamton (Assistant Professor to Full professor, 2010-2020) where he worked alongside Nobel Laureate Prof. M. Stanley Whittingham on several projects (most notably NECCES). He returned to Warwick in 2020. With hindsight, he would not recommend moving in a pandemic.
