further demonstrate that, in addition to decreased crystallite sizes, also the introduction of lattice disorder can enable such pseudocapacitive intercalation properties of MoS2. Manipulating the interlayer distance, i.e., the geometry of the nanoconfined space between individual MoS2 layers, has been described to promote electrochemical ion intercalation reactions by reducing diffusion barriers and increasing available ion storage sites. The use of hydroxy pillars in a "3D porous graphene aerogel decorated with oxygen-incorporated MoS2" led to an expanded MoS2 interlayer spacing from 6.15 to 10.15 Å, resulting in increased Li + intercalation kinetics and storage capacity. Similarly, hollow nanospheres of hydroxycontaining MoS2 nanosheet subunits showed an interlayer spacing between 9.5-10.0 Å, also leading to improved kinetics and capacity of Li + intercalation. Overall, the state-of-the-art literature on MoS2 ion intercalation hosts clearly demonstrates that both, variation of particle/crystallite sizes and tuning of the interlayer spacing are viable strategies to improve ion intercalation kinetics and storage capacity. The former strategy improves kinetics by reducing diffusion distances and suppressing phase transformations, while the latter reduces diffusion barriers and increases storage sites. However, to date, no versatile synthesis approach to control both, crystallite size and interlayer spacing at once has been described. Furthermore, the understanding of MoS2 host-pillar interaction in interlayerexpanded MoS2 is insufficient and it is unclear how pillars behave during electrochemical cycling.
