About this Research Topic
This Research Topic on Layered oxides as electrode or solid state electrolyte for beyond-Lithium Rechargeable Batteries is focused on the synthesis, characterization, computational calculations and electrochemical performance of electrodes or solid state electrolytes for beyond post-lithium (e.g. sodium, potassium, magnesium, Zinc) rechargeable batteries.
Until now, layered transition metal oxides like LiCoO2, LiNi1/3Co1/3Mn1/3O2 are still used widely in portable electronic devices as positive electrodes in lithium-ion batteries (LIBs). This is because layered transition metal oxides have high tap density, energy density and structure stability. Despite the commercial success of LIBs, there has been a strong impetus to further lower the material cost and increase the specific capacity of the cathodes, especially for electric vehicles (EVs), which require high specific energy density to increase the driving range per charge. But given the cost and abundance of Li sources, Na/ K/Mg/Zinc are considered to be viable alternative over Li for large scale energy storage. Since Na/ K/Mg/Zinc have similar physical and chemical properties to Li, materials based on layered structure can be used as cathodes in Na/ K/Mg/Zinc -ion batteries, based on the similar working principle as LIBs. However, the larger radii of Na Na/ K/Mg/Zinc have to be taken into consideration while designing new layered oxides for optimum electrochemical performance.
Better electrode materials for energy storage can be obtained by smart design via a thorough understanding of the underlying mechanism. For this Research topic, we welcome the submission of full research papers, reviews and short communications on the following topics:
- Development of synthesis and characterization methods for layered oxides
- layered oxides as cathode or anode for Na/ K/Mg/Zinc-ion batteries
- Battery component materials (cathode, anode, electrolytes)
- Theoretical work on layered materials for energy conversion
- Optimization and development of new strategies using layered oxides
- Flexible wearable devices
Keywords: layered oxides, sodium ion batteries, potassium ion batteries, electrode
