About this Research Topic
There is an urgent need to develop advanced secondary batteries with high energy density, high security, long lifespan and low cost to meet the ever-growing energy demands. Among various secondary batteries, rechargeable lithium-metal batteries (LMBs) and zinc-metal batteries (ZMBs) are two most competitive and promising candidates. The former is considered the "ultimate goal" of power batteries due to its extremely high energy density, while the latter is expected to be applied in large-scale energy storage fields due to its high safety, low cost, and relatively high energy density. Therefore, the further advancement of these two types of battery systems holds significant practical implications.
The focus of this Research Topic is to optimize metal batteries (Li and Zn) from the perspective of cathode materials, electrolytes, metal anodes and the interface environment between them to enhance the stability and longevity of high energy density Li/Zn metal batteries. Our specific objectives are as follows:
1. Prepare advanced cathode materials with high voltage resistance, strong stability and excellent performance towards high energy density Li/Zn metal batteries;
2. Construct modified Li or Zn anodes with high coulomb efficiency and extended lifespan by adjusting interfacial microenvironments such as electric field, ion distribution, and stress;
3. Solve issues related to matching the cathode material and metal anode within different electrolyte systems via electrolyte engineering based on addressing the stability of metal anodes;
4. Advance secondary high-specific-energy battery systems through a comprehensive understanding of cutting-edge developments and future directions in advanced solutions for modifying Li/Zn metal batteries.
The scope of this Research Topic encompasses the most recent advancements in methods and techniques aimed at enhancing the stability and durability of Li/Zn Metal Batteries, especially high energy density battery systems. Topics of interest include, but are not limited to:
1. Enhancements made to improve the structural stability and high voltage resistance of cathode materials, such as coating and doping for the development of high energy density Li/Zn metal batteries.
2. Specific strategies for optimizing components in direct contact with Li/Zn metal anodes (such as collector, SEI layers and separators), including structure design of Li/Zn metal anodes, construction of artificial SEI layers with high mechanical properties, and modification of separators.
3. Programs for high-voltage resistance and high-performance electrolytes that match the cathodes and metal anodes, such as quasi-solid electrolytes and local high-concentration electrolytes.
4. Universal metal anode interface optimization strategies (for LMBs and ZMBs).
