Introduction Understanding the interaction between water molecules, protons and cations with electrode surfaces is essential for many applications, including electrochemical energy storage, electrocatalysis and desalination.[1-4] In layered 2D materials, such as MXenes, consisting of transition metal carbide and nitrides, confinement effects in the interlayer spacing may provide new avenues to modulate the pseudocapacitive behavior of the host materials[5] or modulate the activity or...

Graphical Abstract A two-dimensional MOF, (Cu3(HHTP)2), is synthesized with two different morphologies. Flake- and rod-like shaped particles were evaluated to investigate the impact of the particle morphology of MOFs on electrochemical Li+ ion storage. By optimization of the particle morphology, diffusion limitation of the Faradaic process can be strongly reduced. Abstract Faradaic reactions including charge transfer are often accompanied with diffusion limitation inside the bulk.

7. Concluding Remarks and Perspectives Current research on rechargeable electrochemical energy storage technologies, such as lithium ion batteries (LIBs), is strongly driven by the run for high gravimetric and volumetric densities, e.g., to increase the driving range of electric vehicles.
