讲座摘要/Abstract:

水系可充锌电池具有成本低、环境友好、能量密度高等优势，在未来规模化储能方面具有重要的应用前景。锌负极仍然是制约水系可充新电池发展的关键瓶颈。人们提出了多种方法来解决锌电池锌负极的关键挑战，即锌枝晶、低可逆性、氢生成和有限的循环寿命。从根本上说，电解质和电极-电解质界面对锌负极的电化学性能起着至关重要的作用。然而，到目前为止，稳定锌负极界面的设计原理还没有得到很好的理解。在本报告中，我们将系统地讨论如何通过不同功能的痕量聚合物添加剂在低成本、低盐浓度水系电解质中稳定锌负极界面，探索低成本、高性能锌负极的设计思路和基本原理，揭示痕量有机添加剂对锌负极反应动力学和反应稳定性影响规律。我们希望通过对电解液添加剂作用机制的理解和探索，为设计低成本和高性能的水性电解质提供了有价值的参考，加快水系可充锌电池的产业化步伐。

Recently, a variety of approaches have been proposed to address the key challenges of Zn anodes for Zn batteries, i.e., Zn dendrites, low reversibility, hydrogen generations and limited cycle life. Fundamentally, the electrolyte and electrode-electrolyte interface play a vital role in the electrochemical performance of Zn anodes. Nevertheless, the principles of stabilizing the Zn anode interface are not well developed so far. In this talk, we will systematically discuss the fundamental principles of developing high-performance Zn anodes in low-cost dilute aqueous electrolytes with a trace amount of functional polymer additives. The correlation between the reaction kinetics and the stability of Zn anodes and polarity of the polymer additive in dilute aqueous electrolytes was revealed. We hope this work could provide useful insight on designing low-cost and high-performance aqueous electrolytes through functional electrolyte additives and speed up the commercialization of rechargeable aqueous batteries.
