- 报告题目：Potassium-based Batteries: Advantages and Challenges
- 报告摘要：The heavy reliance of lithium-ion batteries (LIBs) has caused rising concerns on the sustainability of lithium and transition metal (TM) and the ethic issue around mining practice. Developing alternative energy storage technologies beyond lithium has become a prominent slice of global energy research portfolio. The alternative technologies play a vital role in shaping the future landscape of energy storage, from electrified mobility to the efficient utilization of renewable energies and further to large-scale stationary energy storage. Potassium-based batteries (PIBs) are a promising alternative given its chemical and economic benefits, making a strong competitor to LIBs and sodium ion batteries (SIBs) for different applications. The presentation will discuss the advantages of potassium-based batteries, particularly the K-O2 battery, as well as the challenges associated with their development. Furthermore, our recent progress in potassium superionic conductors will be discussed, which will be crucial in solving challenges in potassium batteries.

- 报告题目：Towards Stable and Safe Potassium Storage in Graphite Electrode
- 报告摘要：Owing to the abundant potassium resources, K+ can be stably inserted in graphite, aluminum foil can be used for both positive and negative current collector, potassium ion batteries (PIBs) are recognized as a promising next-generation energy storage technology. However, the slow diffusion kinetics of K+, the poor structural stability of electrode materials and the unclear potassium storage mechanism hinder the development of PIBs. To address the above issues, our group calculated the K+ migration and transport mechanics in the electrode materials and traditional electrolyte, combined with real-time battery monitoring and in-situ characterization technology to study the effects of crystal structure and microstructure of electrode materials on their capacity and stability. In this report, we will report the use of new high-concentration electrolyte to make the graphite anode stable operation, and the bionic structure to build a stable new carbon material with low platform based on the traditional electrolyte, as well as the design of preparation methods to achieve high quality preparation of graphene and potassium storage, and the regulation of SEI to achieve the stable operation of graphite anode under the traditional electrolyte.

- 报告题目：Key Factor Determining the Cyclic Stability of the Graphite Anode in Potassium-Ion Batteries (钾离子电池石墨阳极稳定循环的关键)
- 报告摘要：Graphite is the most main anode material for lithium-ion batteries (LIBs) and potassium-ion batteries (PIBs). However, the graphite anode in PIBs using traditional dilute ester-based electrolyte systems shows remarkable capacity fading, which is in contrast with extraordinary cyclic stability in LIBs. In this work, by comparing cyclic stability and graphitization degree of graphite anode upon cycling in different electrolyte systems, we reveal that the underlying cause of the capacity fading of graphite anode in PIBs is not the larger volume change of graphite caused by the intercalation/de-intercalation of potassium ions, but the continual accumulation of solid electrolyte interphase (SEI) on graphite surface. By X-ray photoelectron and nuclear magnetic resonance spectroscopies combined with chemical synthesis, it is concluded that the accumulation of SEI may mainly come from the continual deposition of a kind of oligomer component, which blocks the intercalation/de-intercalation of potassium ions in graphite anodes. This finding clarifies crucial factor determining the cycling performance of graphite anode and provides a scientific guidance for practical application of graphite anode in PIBs.
