About this Research Topic
Energy storage devices play an important role in our daily life. However, the most successful lithium-ion batteries (LIBs), recognized by the 2019 Nobel Prize in Chemistry, are approaching their theoretical energy density. Developing high capacity anode materials such as Li metal and Si anodes and high capacity cathode materials with high voltage such as nickel-rich layered oxides and lithium-rich layered oxides are important to increase the energy density. However, the degradation of these aggressive high capacity electrode materials during cycling is one of the key obstacles to upgrading lithium-ion for high-energy applications. Material surface modification as the foremost solution can stabilize their structures and mitigate the undesirable side reactions with the electrolyte. Moreover, the advancement of effective electrolytes under the aggressive electrochemistries is also critical by forming the stable electrode-electrolyte interface to support fast and yet reversible lithium transport through the bulk electrolyte and across interfaces. On the other hand, due to the limited nature and high cost of lithium resources, the development of alternative battery systems such as Na/K/Mg/Zn/Al ion batteries has also attracted worldwide attention for large-scale applications, but many questions still remain about the electrode materials, electrolytes, and electrode-electrolyte interface.
In this Research Topic, surface modification of electrode materials, new types of electrolytes, and electrode-electrolyte interface will be discussed in the perspectives of fundamental chemistry and practical applications to Li/Na/K/Mg/Ca/Zn/Al batteries. Both Original Research articles and Review articles are welcomed in this Research Topic, with the scope including but not limited to:
- Surface engineering on high-performance anodes and cathodes for Li metal and lithium-ion batteries.
- The development and optimization of electrolytes for Li metal and lithium-ion batteries.
- Theoretical and experimental insights on the electrolyte structures, transport mechanisms, and the solid electrolyte interphase formation mechanism.
- Evolution of the surface and interface of the electrode materials by in-situ and ex-situ techniques.
- Development and scientific understanding of electrodes, electrolytes and interface for Na/K/Mg/Ca/Zn/Al batteries.
