Investigation of new electrolyte/electrode interfaces for batteries by dielectric and impedance spectroscopy
In order to solve the bottleneck problems of sulfide-based solid-state lithium-sulfur batteries (poor carrier channels on the cathode, poor interfacial stability on the anode, and poor air stability of the sulfide-based solid-state electrolyte), and considering the advantages of MOFs, such as high porosity, uniform pore distribution, and good stability. Based on my personal research background in lithium-sulfur and lithium metal batteries, I ...
This project aims to develop new architectures for sulfur and lithium electrodes to improve the performance and longevity of the next generation of battery technology, namely lithium sulfur batteries (LSBs). The innovative sulfur electrodes ensure the simultaneous increase in sulfur load and stability of electronic/ionic contacts over short and long distances in the cell. This is achieved through a new approach based on the 'gradual ...
Lithium-sulfur batteries have emerged as a promising option for next-generation energy storage devices due to their high energy density and low cost. However, the two main obstacles for practical Li-S batteries are the notorious lithium polysulfide intermediate shuttle and the sluggish kinetics of sulfur cathodes, especially under lean electrolyte conditions. In this proposal, we propose a detailed plan to gain insight into the degradation ...
Lithium-based batteries will play an increasingly important role in electrical energy storage because of their high energy density. However, current Li-ion technology is insufficient to meet long-term needs (e.g., extended-range electric vehicles). Although intense research efforts have led to significant progress, a major limiting factor is the low cathode capacity. Sulfur is one of the most promising cathode materials because of its high ...
