About this Research Topic
As the technology of renewable energy advances, the need for efficient, cost-saving energy storage remains yet to catch up. Lithium-ion batteries that have enabled cutting-edge electric vehicles, portable appliances and high-power devices over past two decades are nearing fundamental limits in maximization of performance. Post-lithium-ion batteries, mostly Na, K, Mg and Zn with emerging work in Ca and Al, have been investigated, leading to an immense library of novel materials. Despite this exciting emergence of materials, systematic and fundamental studies on designing principles of materials, particularly electrolytes which serve as the bridge and enabler of electrodes, are lacking. The understanding of how electrolytes enable lithium-ion batteries needs to be translated to and unified with advanced and/or multivalent electrolytes in order for next-generation battery technology to succeed.
Therefore, we are calling for papers on original research, perspectives and reviews of systematic and fundamental investigations on advanced electrolyte development. This included but is not limited to Na, K, Mg, Zn, Ca, Al-ion/metal-based electrolytes, in form of solutions, polymers, or glasses. More specifically, the following aspects are the foci:
• Structure-property relationships of electrolytes in electrochemical environments;
• Development of analytical techniques to probe physicochemical dynamical changes of electrolytes in battery-relevant environments;
• Theoretical simulation and experimental characterization on electrolyte-electrode interphase;
• Advances in structural designs and characterization of electrolytes in batteries;
• Comparative electrolyte studies on Li-ion and post-Li-ion battery performances.
We hope that this collection would provide a platform for researchers to unify the understanding of fundamental chemistry of electrolytes in monovalent and multivalent batteries.
