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.
