recommendations! Published in 2020 at "Advanced Functional Materials"

DOI: 10.1002/adfm.202006712

Abstract: Dimensional change in a solid due to electrochemically driven compositional change is termed electro-chemo-mechanical (ECM) coupling. This effect causes mechanical instability in Li-ion batteries and solid oxide fuel cells. Nevertheless, it can generate considerable force… read more here.

DOI: 10.1016/j.apenergy.2021.117315

Abstract: Abstract The electrochemical performance and cycle life of lithium-ion batteries (LIBs) depend on the electrochemical, chemical, and mechanical behavior of electrodes and electrolytes. Despite extensive studies conducted previously, challenges exist to decouple these behaviors, capture… read more here.
