Symposium EN12—Materials for Safe and Sustainable Electrochemical Energy Storage
This symposium will cover recent advances in the development of materials and technologies that focus on electrochemical energy storage (e.g., Li/Na batteries, electrochemical capacitors) with high stability, safety and sustainability for a broad range of applications, such as portable electronics, electric vehicles and smart grids.
Electrochemical energy storage devices continue penetrating deeply to our daily life and industrial uses. With the increase of energy density and power density of these devices, stability and safety become increasingly critical due to the higher electrochemical activity of electrode/electrolyte materials and larger scale of storage systems, in which reliability is the first concern. Significant effort has been made in the development of new materials and structures that can provide significantly higher energy density, while maintaining high safety features becomes challenging. This includes novel electrode materials, electrolyte materials, separators, current collectors and functional additives. In addition, novel device engineering strategies have been also explored to offer early diagnostic and safety management and protection. At the same time, the rapid growth of energy storage market has significantly boosted the demand and consumption of precious materials (e.g., Co, Li, Ni), which starts to draw concerns about resource shortage and materials sustainability. This symposium will provide a forum for scientists and engineers to communicate their recent progress and exchange ideas in these topics. Most recent advances in different electrochemical systems will be covered, including safe organic electrolytes, ionic liquid electrolytes, solid state electrolytes, aqueous electrolytes and hybrid systems. Both traditional Li+ chemistry and beyond Li+ chemistries (e.g., Li-sulfur, Li-metal, Na-ion) will be of interest, while multivalent batteries will not be included in this symposium. Submissions that report on green materials, chemistry and engineering methods for improving life-cycle efficiency and sustainability are also encouraged.
