Batteries beyond Li-ion : viability of alternative chemistries

Orateur : Rosa PALACIN (Institut de Ciencia de Materials de Barcelona (CSIC) - Bellaterra - Catalonia - Spain)

The interest in new battery chemistries as an alternative to the ubiquitous Li-ion has boosted in recent years as a result of both sustainability concerns related to the availability and cost of lithium raw materials and the quest for an ever increasing energy density. The Na-ion technology holds promise for accelerated development thanks to the knowledge gained in the “chemically similar” Li-ion while alternative chemistries based on multivalent ions are still facing important bottlenecks. The talk will review recent research at ICMAB-CSIC aiming at the development of negative electrode materials and electrolytes for Na-ion batteries and assembly/performance of laboratory full Na-ion cells. Initial efforts towards multivalent metal anode based technologies will also be discussed.
