“…Shortly after the synthesis of MXenes,12 their possible application as anode materials for Li ion batteries (LIBs) has been explored greatly and these MXenes exhibit good capability for high charge–discharge rates 14, 17, 18, 19. Besides LIBs, other applications, such as non‐Li‐ion batteries,20, 21 hydrogen storage,22, 23 supercapacitor,24 and thermoelectric materials,25 have also been investigated.…”
