Lecture Title: High-Efficiency Electrical Energy Storage Using Reversible Solid Oxide Cells
Lecture Abstract: Electrical energy storage is a key technology needed for enabling increased utilization of renewable wind and solar energy resources. While many technologies are being considered, the grid “load shifting” application – storing excess electricity for several hours until there is demand – remains challenging. This presentation will discuss the use of reversible solid oxide fuel cells for grid-scale energy storage. Fuel cells can provide large energy storage capacities by using large storage tanks/caverns for product gases, but until recently have not been strongly considered because of low round-trip efficiency. A new method for improving efficiency will be described, utilizing a new storage chemistry where the fuel cycles between H2O-CO2-rich and CH4-rich gases, allowing much-improved round-trip efficiency > 70%. For this application, however, improved solid oxide cells are needed that can provide useful current densities at relatively low overpotentials and ~ 600oC. A candidate being developed in the Barnett group, utilizing doped lanthanum gallate electrolytes, will be described. Results on the stability of solid oxide cells under thousands of current-switching cycles, a key question that has not previously been explored, will be presented.

Lecture Title: Design and Characterization of Electrode Materials for High-Performance Supercapacitors
Lecture Abstract: The ever-increasing demand for clean and secure energy has stimulated an intense search for efficient electrical energy storage systems of high energy and power density. For now and in the foreseeable future, supercapacitors represent one of the most attractive options for a diverse range of applications that require rapid power delivery and recharging, from portable electronic devices to electric vehicles and smart grids. However, the performances of the state-of-the-art supercapacitors are still inadequate for many intended applications. The development of a new generation of high-performance supercapacitors depends on the creation of novel electrode materials and structures that may dramatically accelerate the rate of mass and charge transfer processes associated with electrical energy storage. In this presentation, recent progress will be highlighted in investigations into the charge storage mechanisms of promising electrode materials using in situ and operando Raman spectroscopy and density functional theory (DFT)-based calculations. Fundamental understanding of the mechanisms is vital to achieving knowledge-based design of more efficient electrode materials. Perspectives for a new generation of hybrid supercapacitors will also be discussed.

Lecture Title: Electrical Energy Storage: Materials Challenges and Prospects
Lecture Abstract: Rapid increase in global energy use and growing environmental concerns have prompted the development of clean, sustainable, alternative energy technologies. Electrical energy storage (EES) is critical to efficiently utilize electricity produced from intermittent, renewable sources like solar and wind as well as to electrify the transportation sector. Rechargeable batteries are prime candidates for EES, but their widespread adoption for electric vehicles and grid storage requires optimization of cost, cycle life, safety, energy density, power density, and environmental impact, all of which are directly linked to severe materials challenges. After providing a brief account of the current status, this presentation will focus on the development of advanced materials and new cell chemistries for next-generation battery technologies. Particularly, the challenges and approaches of transitioning from the current insertion-compound electrodes in lithium-ion batteries to new conversion-reaction electrodes with multi-electron transfer to increase the energy density and lower the cost will be presented. Specifically, battery technologies based on lithium and sodium as working ions with high-nickel layered oxides, sulfur, and solid electrolytes will be discussed. The challenges of bulk and surface instability during charge-discharge cycling, advanced characterization methodologies to develop an in-depth understanding, and approaches to overcome the challenges will be presented.

Lecture Title: Interfacial Mesoscopic Phenomena in Electrochemical Systems
Lecture Abstract: Complex chemical-physical phenomena, such as reactive transport, heat transfer and hydrodynamics, are critical to the operation and performance of advanced electrochemical systems. The critical physics of these systems occurs at the meso-scale interfaces between phases, such as the electrode-electrolyte interfaces in batteries and fuel cells. Experimentally visualizing interfaces is challenging due to their small scales, imbedded nature and complex geometry. Computational modeling is a powerful tool for understanding the physics within these energy systems, especially at interfaces. In this talk I will discuss research into the development of computational methods for the simulation the electrode-electrolyte interface of lithium batteries for the study of dendritic growth. This research focuses on understanding the fundamental driving forces for dendrite growth and exploring strategies for suppressing dendrite growth, including the use of novel electrolyte materials and structural designs.

As concerns of greenhouse gas emissions and climate change mount, humanity is being forced to address its impact on the environment. In the field of stationary power generation, there is an acute need for grid-based and distributed energy conversion and storage technologies to accommodate increasing off-peak generation of renewable energy.
Critical advancements must be made in the areas of grid storage capacity and fuel-adaptable distributed-energy generation. In the transportation sector alone there is an urgent need for carbon-neutral technologies that deliver higher energy and power densities, longer drive distances and longer lifetimes, and faster recharge times.
A plethora of high-efficiency devices and systems are being considered to meet these challenges including fuel cells, high temperature electrolyzers, novel batteries, and supercapacitors. Central to the functioning of these devices is the interplay of structure, interphases, charge transfer at electrochemical interfaces, and the transport of charge and mass in response to electrochemical driving forces. The pursuit of long lifetime and reliability hinges on understanding time-dependent phenomena at electrodes and electrolytes that occur at various length scales.
The event will feature leading scientists and technologists in the field of electrochemical and energy conversion and storage. It will cover leading edge research on the discovery and synthesis of the materials, structures, architectures, in addition to design strategies.
