Sodium and potassium benefit from abundant resources as well as physical and chemical properties analogous to those of lithium. This is why they are currently being studied as a replacement element for lithium. As a low costs solution without critical materials, sodium-ion batteries (SIBs) and hybrid potassium-ion supercapacitors (KIC) are promising for energy and high power applications, respectively. Main results obtained at CEA in several projects will be presented.
