Special Issue Information

Dear Colleagues,

With the proposal of the carbon peak and carbon neutral target by governments all over the world, the green chemical power supply will play an increasingly important role in our lives. As you all know, lithium batteries have been widely used in all aspects of our lives, such as portable electronics, electric vehicles, renewable energy storage, smart grids, backup power supplies, etc. High safety, high specific energy, high specific power, low cost (resource availability) are the development goals of electrochemical energy storage batteries, which depends on the research and application of new electrode materials, new electrolyte and new battery structures.

In recent years, the research of solid-state batteries has become a hot spot, including the development of new solid-state electrolyte materials, the improvement of chemical and electrochemical stability, and the design of electrode and electrolyte structure. Electrode materials with high specific capacity, stable structure and stable interface between electrode materials and the electrolytes are the key factors to build batteries with high performance. Sodium is abundant in the Earth’s crust; therefore, sodium ion battery is considered to be one of the most promising candidates for the next generation of electrochemical power sources, and more and more research is focused on the basic issues of sodium ion batteries.

This Special Issue will report recent developments in the field of Li/Na batteries.  The articles presented in this Special Issue will cover various topics, including Li/Na ion batteries, Li/Na sulfur batteries, Li/Na oxygen batteries, Li/Na solid-state batteries, ZEBRA batteries and related solid electrolytes, interface engineering between electrode and electrolyte, protection strategy of Li/Na electrode, materials diffusion and charge transport mechanisms, etc. Topics are open to Li/Na batteries for the development of applications.

Real-time structural changes in Na-β″-alumina were observed in situ using transmission electron microscopy (TEM) with electron beam irradiation. Na-β″-alumina has been widely investigated as a solid electrolyte material for sodium–sulfur secondary batteries owing to its high ionic conductivity. This high conductivity is known to be due to the Na+ ions on the loosely packed conduction planes of Na-β″-alumina. In the present study, we acquired real-time videos of the generation of spinel blocks caused by the conduction of Na+ ions. In addition, by observing Na extraction during electron beam irradiation, we experimentally confirmed that spinel block generation originates from the Na+ ion conduction, which has been a subject of recent debate.
