The last decade has shown an extremely fast rise in the development of rechargeable batteries for electrification on transportation. Expectations are high, as countries world-wide tend to abandon cars with internal combustion engine. Lithium ion batteries dominate the market, yet the growing mass market also leads to concerns regarding the sustainable development of this huge field of (electro-)chemical technology.
In this keynote, the current technological status of lithium ion batteries will be briefly reviewed, and existing chemical challenges on the way to further improvements are highlighted. Research on alternative “cell chemistries”, i.e. cell concepts, is presented by own examples, and current research trends (e.g. solid-state batteries, sodium ion batteries) are analyzed with respect to their potential as future storage concepts.
Finally, techno-economic considerations (e.g. resources, materials supply, CO₂ footprint) need to be considered as important boundary conditions and constraints for the success of electrochemical energy storage.
