Abstract: Electrochemical Energy Storage beyond Lithium-Ion Batteries

Lithium-ion batteries (LIB) have become the electrochemical core storage technology, and their field of application widens day by day. This also raises the question whether there will other elec-trochemical cell concepts that may take their place next to LIB. Two major directions of research and development are being pursued today: First, the quest for lithium-based batteries with even higher performance in terms of stored energy per mass or volume, rate of charging, durability, sustainability and cost. This explains the strong trend for solid-state batteries with high capacity anodes (particularly lithium metal). Second, the search for alternative battery cell concepts that may offer advantages in terms of the use of natural resources avoiding critical supply chains, re-ducing the carbon footprint of the battery and its cost. This explain the research in so-called “post-lithium” concepts, i.e., sodium ion batteries, magnesium-based batteries, organic redox batteries and others.

This lecture will then mainly provide an overview of the current research perspectives in this field, and will focus on the question whether solid-state batteries can surpass the current lithium ion technology based on liquid electrolytes. As part of this, the potential role of the lithium metal anode will be discussed, and both in situ and operando experiments on the function of the lithium metal anode will be presented. Whether sodium ion batteries and their solid-state versions can also suc-ceed will additionally be briefly discussed.
